How to Fix Microsoft Teams Chat Messages Not Sending or Showing Up?

Find that messages on Microsoft Teams are loading only hours later or not sending or showing up at all?

If the messaging or notification system in Teams, both crucial features, don’t work properly, then that makes it kind of useless since that’s the whole point of the platform! You could potentially miss an important event or update because of it.

 


Types of Messaging Errors on Microsoft Teams

We’ve seen a lot of people report such issues regarding messaging and notifications in Microsoft Teams. More specifically, symptoms include:

For instance, many Microsoft Teams users find that messages get sent with delay or aren’t even sending at all with the error message “Failed to send”.

1. Log Out and Log Back Into Microsoft Teams

Yes, as trivial as it may seem, we’ve done some digging and this is actually one of the ways you can resolve this annoying issue. A simple logout and login refreshes the app and it only takes a few seconds to do, which is why we put it first for you to try.

However, even if it does solve the issue, we’ve seen user reports of the issue cropping back up a few hours after the fix, so you may need to redo it.

Regardless, here’s how to do that on desktop and mobile:

 

Windows/macOS

  1. Firstly, click on your profile on the top-right corner of the Teams window.
  2. Then, in the context menu, simply click Sign out.

sign out and back in to the Microsoft Teams desktop app on Windows or macOS to fix Microsoft Teams chat messages not sending, showing, loading or working

 

  1. Once that’s done, you can log in as usual at the login page.

sign back into the Microsoft Teams app or website on desktop on Windows or macOS to fix chat messages not sending, showing, loading or working

 

Android/iOS

  1. First, open the sidebar by selecting your profile on the top-left corner of the app.

2. Check and Change the Channel Permissions

Like all major communication platforms, Teams has an option to set channel permissions to restrict and control which users get to post messages in channels. Of course, this is a good way to make sure there’s order within the team, but it may also inadvertently be the reason why your members aren’t able to post in the channel. Hence, possibly giving the members the impression that their messages aren’t sending or showing up on Microsoft Teams.

Unfortunately, these settings can’t be changed on the mobile app. So, here’s how to check for those permissions on desktop:

  1. To start, in the left sidebar with all your teams and channels, click on the three-dotted icon for the channel you wish to check permissions. 

Note: This is NOT the three-dotted button for the team, but for each individual channel in the team.

  1. Then, in the context menu, click on Manage channel.

  1. Next, the chat box will be changed to a settings page, where you can change the channel’s permissions under the Channel settings tab.
  2. Finally, make sure to have the General channel section set to Anyone can post messages.

check and enable channel messaging permissions to fix Microsoft Teams chat messages not sending, showing, loading or working

 

 

3. Restart the Microsoft Teams Application

Following the trend of easy fixes first, we highly recommend restarting the app as this seemed to have fixed the issue for multiple users. You know how software can be at times!

However, in some cases, simply closing the Teams window doesn’t completely close the app, so this is how to thoroughly do it. Plus, you’ll need to ensure that all instances of the Teams app are completely closed for a thorough restart.

Therefore, at times, it might even be a better idea to restart your device as well to completely end all background processes which are inessential and potentially conflicting.

 

Note: For all these methods, you’ll want to save any unsaved work before stopping them, as Teams will be forced to stop running.

 

Windows

  1. To start, open the Task Manager by pressing Ctrl + Shift + Esc on your keyboard.
  2. Simply select the Teams app then click on End task in the bottom-right corner of the Task Manager’s window. Alternatively, you can right-click the task and select End task.

macOS

  1. Start by opening the Force quit application menu by holding down Command + Option + Esc.
  2. In the menu, select Microsoft Teams and click Force Quit.

Android

There’s a lot of different flavors of Android, so the steps won’t be exactly the same depending on the brand of phone you have. Nonetheless, they’re all very similar so it shouldn’t be too hard to follow these steps.

  1. First, access the recent apps menu.
  2. Then, long press on the Teams icon and select App info.

access Microsoft Teams App Info to close and restart app on Android to fix Microsoft Teams chat messages not sending, showing, loading or working

 

  1. In Teams’ app info, simply select Force stop.

  1. Finally, open the Teams’ app as usual.

 

iOS

  1. First, access the recent apps menu. If you’re using an iOS device without a home button, swipe up from the bottom of the screen. Otherwise, double-tap on the home button.
  2. Then, simply swipe the Teams app up and away.

4. Try the Web Version of Microsoft Teams

As Microsoft themselves suggest, we can troubleshoot the root of the issue by checking if the web version of Teams doesn’t exhibit this issue. Hence, if the issue isn’t present on the web version, then it may be a problem with the client app on your device. So, this could mean that Microsoft is yet to release for the 

Keep in mind that the Teams’ web version only works on Chrome, Edge or Safari. It goes without saying that only those on desktop should use the web version as navigating a desktop website on a phone is certainly not ideal.

Therefore, click here to visit the web version of Microsoft Teams. There, you’ll have to Sign in to your Microsoft account that you use for Teams to access your teams and calls.

use the web version of Microsoft Teams to fix Microsoft Teams chat messages not sending, showing, loading or working

 

If you find that Teams isn’t working on your particular day-to-day web browser, try using a different browser. Perhaps there could be problems with the initial browser such as cache and cookies, browser settings, optimization problems, etc. resulting in your Teams issue.

Alternatively, if Teams isn’t working on your web browser, you can try installing and using the desktop application instead. For this, simply visit the Microsoft Teams Downloads page, and select Download for Desktop, to get the client installation file fit for your OS.

 

 

5. Use Microsoft Teams on a Different Device

You can take this a step further, and even try using Microsoft Teams on a different device. This will help you troubleshoot any errors with the initial device that’s resulting in your Microsoft Teams messages not sending or showing up. This is especially a handy troubleshooting step when the Chat option isn’t showing on the sidebar. Hence, you can find that even Microsoft themselves recommend this step for this purpose.

For instance, if you encountered messaging issues when using the desktop application, test the mobile app on your phone. You can attempt to either load new messages 📬, send your intended texts 📧, or even to just check if the Chat option is showing.

6. Check Microsoft Team’s Server Status

Moving on, if the web version doesn’t work either, then we can confirm by checking if it’s a server-side issue. So, it’s always a good idea to check if the servers hosting the service in question are acting up. This can evidently save you a lot of time if you know the problem is something you can’t fix yourself, as is the case with server-side issues.

While there’s a bunch of websites that track the status of various popular servers for free, we highly recommend using Downdetector.

Check Microsoft Teams server status on Downdetector if chat messages not sending, showing, loading or working

 

In addition to displaying server status in big and bold lettering at a glance, it informs users about the affected regions. It also has an embedded feed of @MSFT365Status, Microsoft’s official Twitter account for reporting any issues with Microsoft 365 services such as Teams.

If Downdetector says there are server issues and both the client and web versions have messaging issues, then that’s a pretty good indicator that it’s indeed a server-side issue. Unfortunately, there’s nothing much you can do about this other than to contact them through their official channels and report the problem (Step 16).

Luckily, issues with services like these usually take only a few hours to a day to resolve. So, sit tight and perhaps use an alternative communication platform such as Slack.

We have a list of official Microsoft Teams support channels and what to tell them in Step 16 should you need it.

Nonetheless, we still recommend trying the other fixes below just in case the problem resides locally.

 

 

7. Update the Microsoft Teams Application

If their servers are working fine, then it’s likely that the issue resides somewhere on the client’s end. It’s always a good idea to keep your application updated as it usually introduces new features and irons out any bugs 👾 like the messaging issue. Plus, updating is pretty easy to do!

Hence, there could indeed be a pesky app bug resulting in your Microsoft Teams messages not sending or showing up correctly.

Of course, this won’t apply to you if you use the web version of Teams. Nonetheless, it’s really easy to do on any platform. So, just jump to the relevant section and follow along:

 

Windows/macOS

The client’s user interface for both Windows and macOS are the same, so naturally, the same steps will apply to both operating systems. This one’s really straightforward:

  1. To start, open up the Teams app.
  2. Then, click on the three-dotted button beside your profile photo in the top right of the app.
  3. Next, click on Check for updates in the drop-down menu.

check for Microsoft Teams client/app updates on Windows or macOS to fix Microsoft Teams chat messages not sending, showing, loading or working

 

  1. Finally, if there are any updates, let them download and install.

 

Android/iOS

Again, similar to the Windows and macOS reasoning, since both of these apps come from app stores, the process will be similar for both. That’s the Google Play and the App Store for Android and iOS respectively:

  1. First, open the appropriate native app store for your device.
  2. Search for Microsoft Teams and select the listing. Here’s a link to the listing for Google Play and the App Store.
  3. If there’s an update for the app, you can tap the Update button and let it do its thing.

check for Microsoft Teams app updates on Android or iOS to fix Microsoft Teams chat messages not sending, showing, loading or working

 

 

8. Try Messaging Another User or in a Different Channel/Team

Perhaps there could be issues on the receivers end, whether server-side problems, internet connection issues, or setting configuration errors. So, these problems could give you the impression that your messages on Microsoft Teams aren’t sending or posting whether to a user or in a particular team/channel.

Therefore, we recommend this troubleshooting step to identify whether the issue is truly on your end.

Try messaging another user or in a different channel or team to fix Microsoft Teams chat messages not sending, showing, loading or working

 

So, if other users and channels find that your messages are successfully sent, it may just be an issue with that particular user or channel. Hence, the Teams channel may possess restrictive permissions settings that need reconfiguring (Step 2).

Otherwise, if your Microsoft Teams messages are still not sending, this could then be a problem on your end. Thus, you can proceed to try the other fixes. 

 

 

9. Disable Your VPN or Proxy

VPNs are an excellent addition to your Internet browsing activities, especially with ever-growing concerns for online privacy. However, for Teams to work properly, it needs unrestricted access to Microsoft’s servers, so having a VPN may actually prove to be detrimental. 

To rule this out as a possibility, try disabling your VPN and restart Teams as we detailed in step 3. If the messaging issues go away, then you’ll have to reconfigure your VPN to allow Teams services to go through uninterrupted, or whitelist it. Otherwise, try our other fixes listed below.

10. Refresh Your IP Address or Flush Your DNS

Seeing as Teams is a communication platform, networking inevitably plays an important role to ensure its functionality. Thus, we recommend refreshing your device’s IP address and flushing your DNS so that everything stays in order. The DNS, in particular, could be corrupt so it’s a good idea to reset it for a brand new set to be made.

Thus, possibly resolving your network connectivity issues that are resulting in messages not sending or showing up on Microsoft Teams.

That being said, the following steps show how to refresh the IP address data and flush the DNS cache on your desktop:

 

Note: This fix does not apply to Android or iOS.

 

Windows

  1. Firstly, right-click on the Windows icon or Start button in the bottom-left corner of your desktop.
  2. Then, in the context menu, click on Windows PowerShell (Admin)

access Powershell on Windows to refresh IP address and clear DNS cache to fix Microsoft Teams chat messages not sending, showing, loading or working

 

  1. In the PowerShell window, copy and paste this command to refresh your IP address: ipconfig /renew
  2. After that, hit enter on your keyboard and wait for it to complete. You’ll know it’s done when it shows your current directory.
  3. Then, repeat steps 3 and 4 but with ipconfig /flushdns so that your DNS cache is reset.

  1. Lastly, close the terminal once it’s done.

 

 

11. Clear the Microsoft Teams App Cache

Cache is used by apps to quickly load frequently accessed resources or pages so that you have a faster and more responsive experience. Unfortunately, they’re also susceptible to corruption so you should try clearing them whenever you encounter issues. This forces Teams to create brand new caches which are likely not corrupted and could resolve the messaging issue.

Likewise, if you’re using the web version of Microsoft Teams, cache, cookies 🍪, and other site data are stored on your web browser.

That being said, the following are steps to clear the Microsoft Teams app cache on whichever device you might be using:

 

Windows

  1. Firstly, ensure the Teams app is fully closed and not running. You can double-check by looking in the Task Manager (Ctrl Shift Esc). End the Teams process in there if you see it running. (Step 3)
  2. Next, open up the Run dialog. (Win + R)
  3. Copy and paste the following address to access Teams’ cache: %appdata%/Microsoft

access Microsoft Teams cache and app files to clear cache on Windows to fix Microsoft Teams chat messages not sending, showing, loading or working

 

  1. You should see a list of folders in here like in the screenshot.
  2. Then, simply select Teams and delete it.

  1. Finally, open up Teams and let it set up all the new cache.

 

Web Version

The following steps were performed on Google Chrome, but are generally similar regardless of whichever browser you’re using:

Note: Clearing cookies and site data will log you out of the website, so save everything before you perform these steps.

  1. First, navigate to the Teams web version and log in.
  2. On the left side of your address bar, click on the lock or similar.

Note: Another simple method to clear Teams app cache on mobile OSes without digging into system files is to simply reinstall the app (Step 12). Uninstalling the app removes the stored cache so this approach works.

 

 

12. Reinstall the Microsoft Teams App

Now that you’ve cleared the Microsoft Teams app cache, you can take another step and completely reinstall the app as well. From the previous step, we’ve deleted all the app files of the Teams client. Hence, this allows us to perform a complete reinstall, where we can simply uninstall the client and afterwards download and install a fresh copy of the Teams app from their website.

Thus, this new app can be free from possible corrupted installations or hidden lingering bugs. Therefore, making it another go-to solution for various Microsoft Teams problems, including messaging errors. 

 

Note: For a complete reinstall, you can delete the Teams files through the previous step beforehand. Additionally, restarting your device after the uninstallation is helpful for a complete reinstall as well.

 

Windows

  1. First, open the Run prompt by pressing the Windows and keys together. 
  2. After that, enter appwiz.cpl and click OK.

completely uninstall and reinstall the Microsoft Teams client on windows to fix chat messages not sending, showing, loading or working

 

  1. From the list of apps, select Microsoft Teams and click Uninstall.

  1. After that, proceed with the rest of the guided uninstallation steps.
  2. Finally, you can visit this Microsoft page, to download the Teams client installation file and proceed to run it.

 

macOS

  1. Firstly, open up Finder and look for the Microsoft Teams app. It’ll likely be in the Applications tab, which you can open by clicking Applications in the Finder’s sidebar. Alternatively, you can use Spotlight to find the app, then press and hold the Command (⌘) key while double-clicking the app in Spotlight.
  2. Then, drag the Microsoft Teams app to the Trash, or select right-click the app and choose Move to Trash.

  1. Finally, reinstall it by selecting the Install button.

Once that’s done, open up the newly-installed Microsoft Teams app and check if your messages are still not sending or showing up correctly.

 

 

13. Allow the Teams App Through Your OS Firewall

As a safety precaution, many desktop operating systems like Windows and macOS have a firewall 🔥 to block and allow ingoing and outgoing connections. They protect your device from any unsolicited data from unknown sources, working especially well against malicious hackers who wish to send you viruses.

If your firewall doesn’t allow Microsoft’s servers to connect to your computer and send data such as messages from your teams, then you definitely won’t receive them. The same can apply for the reverse — you won’t be able to send messages to your team since your firewall has prevented you from ever interacting with Microsoft’s servers.

Thus, restrictive firewall settings could be the culprit for your Microsoft Teams messages not sending or showing.

The proper permissions should have been given upon Teams’ installation, but it doesn’t hurt to have a look at the permissions just to make sure:

 

Note: This fix doesn’t apply to Android or iOS.

 

Windows

  1. Start by holding Win + S or click the search bar in the bottom left.
  2. Then, search and select Allow an app through Windows Firewall.

  1. After that, click the Add button under the list of services, then select the services or apps you want to add – in this case, Microsoft Teams. After an app is added, click its up and down arrows to allow or block connections through the firewall.

 

 

14. Check Your Network Firewall

An OS firewall is quite common and nifty to have, but it can also exist in the network itself as hardware or software. If the issue occurs on your company’s network, then we recommend asking your network administrator to check on the firewall system they have — it may be preventing Teams from working properly.

On the other hand, if the issue is at home, then you can take a look at your router’s built-in features. Many modern routers have built-in software firewalls so we recommend taking a look at what exactly they filter as they may be blocking some of Teams’ features. A quick Google search for something along the lines of “how to access [router model here] router settings” should yield some useful results.

15. Set the Policy Settings

You can think of policy settings as a higher level of permissions for everyone in that Team’s organization. As such, these settings are only accessible to the admin. So, unless you’re the admin, you’ll need to contact them to check if this is causing the messaging problem. 

This is mainly to solve the issue where you don’t have permission to message in a particular channel or team, or if the Chat option isn’t showing.

Nonetheless, this is how to alter those policy settings to ensure the chat feature is enabled:

  1. First, go to the Microsoft Teams Admin Center.
  2. Then, on the left sidebar, select Messaging policies

set the Microsoft Teams Messaging policy settings to fix Microsoft Teams chat messages not sending, showing, loading or working

 

  1. In the Messaging Policies page, select the Global option. Alternatively, you could also create a totally new policy.

set the Microsoft Teams Messaging policy settings to fix Microsoft Teams chat messages not sending, showing, loading or working

 

  1. After that, in the Global policy settings page make sure Chat is enabled.

set the Microsoft Teams Messaging policy settings to fix Microsoft Teams chat messages not sending, showing, loading or working

 

  1. Finally, scroll down and click on the Save button in the bottom left corner of the page.

 

After making the changes, you can restart the application (Step 3) or even clear its cache (Step 11) for an improved effect.

If that didn’t work, you may have to create a new custom messaging policy. This will reset the settings of the particular Team to their default configurations, which freely permits messaging by members.

 

 

16. Check if Your Team is on “Teams Only/Islands” Mode

Another setting to check for on the Teams admin console at the messaging policy is whether the particular Team is configured for Skype Only. So, when it’s configured for Skype only, you won’t get the Teams privileges, such as members being able to send messages. Instead, it should be set to Teams Only or Islands.

For more information on these 3 modes and their capabilities, we recommend checking this guide by Microsoft to help you to make the right upgrade choice.

That being said, like before, you can check this at the Microsoft Teams Admin Center under Account, Teams Upgrade, and Coexistence Mode.

From there, if you notice that your Team is on Skype Only mode, you can change it to Teams Only. To do this, you can find the steps to perform this upgrade (from Skype for Business Online to Teams) in this guide by Microsoft.

17. Contact Microsoft Support

Tried every single thing on this list but still encountering the pesky messaging issue? It’s likely a problem on Microsoft’s end with their servers and that always sucks since you usually can’t do anything about it other than reporting the issue to Microsoft themselves. So, here are some links to their official support channels:

Regardless of which channel you choose, be sure to give them a detailed explanation of your issue, how to replicate it and what you’ve tried so far to remedy it. Furthermore, other users may be reporting the same issue as you. Hence, Microsoft may have already responded with a specific fix or announced what’s wrong on their end — keep a lookout for them.

Conclusion

Well, there you have it! Those were our 17 fixes for when Microsoft Teams chat messages are not sending or showing up.

Even an integral part of a communication platform, such as messaging and notifications, tends to have occasional issues like these. However, admittedly, part of that could be blamed on the potentially complex networking systems. As internet services get more complex, we inevitably have to troubleshoot every single point of failure whether that be Teams’ cache, firewalls or even Microsoft’s own servers just to name a few.

We know it can take hours of Googling and troubleshooting to find out what’s actually wrong with whatever application has an issue, especially if it’s something like Teams. So that’s precisely why we compiled all of the fixes we’ve discovered and tried ourselves for your convenience. Worst comes to worst, none of the fixes works and you’ll have to report the issue to Microsoft themselves.

All in all, hopefully, this article managed to help you in some way, at least a little bit!
