The most common Microsoft Teams problems, and how to fix them

Microsoft Teams was introduced in 2017 as a unified communication and collaboration platform, helping businesses and organizations get things done. Microsoft leveraged the company’s existing Office software experience and created a unified experience between Teams, Office 365, and Skype for Business. However, as with all software, things don’t always go according to plan. If you’re having Microsoft Teams issues, here’s how to fix some of the most common problems.

How to check if Microsoft Teams is down

If you’re starting your day by asking yourself “is there an issue with Teams today?” You’re most probably not alone. As with any software, various issues may crop up on Teams from time to time. While these problems might be on your end, it’s best to rule out any issues on Microsoft’s side before you delve into heavy troubleshooting.

First, check the official Microsoft 365 Status page or the Twitter account used for the same purpose. Look out for any recent tweets pertaining to Teams. Microsoft reports technical problems on this account, so if there’s a recent announcement, all you can do is wait. You can also check the official Microsoft Teams Twitter account or search for the #MicrosoftTeams hashtag. If there are multiple people reporting problems with Teams, you can sit back and rest easy until Microsoft itself gets it fixed.

If Twitter didn’t help, you can turn to a service such as Downdetector. If there is a spike in reported Microsoft Teams problems, scroll down and check if the other users in the comments left any useful insights. Microsoft itself doesn’t report outages to third-party websites, though, so you may not get a real confirmation here.

Lastly, ask your colleagues if they’ve experienced any Microsoft Teams issues in the last few hours. Your organization as a whole may be affected.

Assuming that Teams works for mostly everyone except you, keep reading to get it fixed.

Bug: Teams only shows older messages and threads

If you aren’t receiving the latest messages from your colleagues, or your feed appears to be frozen in time, we would recommend restarting the application.

To restart Teams on Windows 10, look for the Teams icon (a small purple and white icon of two people and a T) in the taskbar in the lower-right of your screen — you may need to click a little arrow to expand the taskbar. Once the icon is located, right-click it and select Quit. On MacOS, right-click the Teams icon in your Dock, then choose Quit. Now, reopen the application to see if your problem has been solved.

If you are still having Microsoft Teams issues when it comes to loading the latest messages, check your internet connection to ensure everything else is working fine. You can do this by simply opening your browser and heading to a reliable website you often visit. Check a few different websites to make sure your internet is not disconnected or slow. You can also verify it by running a test on

Microsoft Teams also has a web version that you can try if the app is misbehaving. Sign in at and check if your messages are loading there.

Problem: microphone or webcam refuses to work correctly

If you’re having Microsoft Teams issues with your webcam or microphone, begin by ensuring that your hardware is plugged in correctly. Next, ensure that during a meeting, your microphone and webcam are enabled — you will see toggle switches for these options when you join a new call.

If other applications can see your webcam and microphone but Teams cannot, you may need to allow permissions for Teams. To alter permissions on Windows 10, click the Windows search bar (located within the left side of the taskbar) then type in “Webcam.” After selecting Choose which apps can access your camera, make sure the toggle underneath Allow desktop apps to access your camera is switched to the On position. Then scroll past the toggle to make sure that Teams and the browser apps you use to access the web version of Teams are included in the list of apps that have been granted this permission.

To alter Teams’ permissions on MacOS, click the Apple icon in the upper-left corner of the screen, then choose System preferences. From here, select Security & privacy, then Camera — you may need to click the Lock icon to make changes here. Ensure that Teams or the web browser you are using to access Teams is enabled on the right.

If that didn’t help, make sure you have the latest Windows or MacOS update available as well as the latest version of Teams itself. Updating Teams is easy — click on your Profile photo in the top-right corner of the app and tap on Check for updates. While you’re at it, check if your internet connection is working fine by visiting a few of your favorite websites.

You should also verify whether your camera is not currently being used by another app, such as Skype or Whatsapp. You can do this by closing all the other messenger apps that could possibly take control of your camera.

If you’re using Teams in English, you can make a test call to check whether everything is fine on your end — after all, it could be an issue with Teams. At the top-right of Teams, click on Settings and More Settings > Devices. Under Audio devices, select Make a test call.

Problem: you are unable to create a new team in Microsoft Teams

If you are attempting to create a new team in Microsoft Teams, but cannot, check with your system administrator. Companies and organizations have the option to disallow individuals from creating new groups or teams. Reach out to your IT department for further assistance with the matter.

Assuming you are the one in charge of creating new teams for your organization, you may have reached the limit for teams assigned by Microsoft to your company account. There might also be an issue with administrator permissions given to your user account. In both cases, you should reach out to the vendor who manages your organization’s Microsoft Teams access or to Microsoft itself via the support channels.

Problem: removed user shows as ‘Unknown User’ in Teams

Microsoft is currently aware of an issue in which a removed user will show as Unknown User in the Teams application. The conversation tab may also say “Unknown User Has Been Added to the Team.” There is no fix at this time, but Microsoft is working on the problem.

Problem: Unable to establish a connection to Microsoft Teams

If you’re having problems accessing Teams, make sure that your Mac, PC, or mobile device can access other networks or internet content. If your computer is connected to the internet but Teams is still inaccessible, the service might be down. Check with Microsoft’s Support page to see if they are having problems with the Teams service.

Most of the fixes we’ve gone over above are also helpful here. Update your Teams app to the latest version by clicking on your Profile photo in the top-right corner of the app. Select Check for updates and let the software do its job.

Assuming the Teams app doesn’t work for you, you can always try to access it through the web client on the official Microsoft website.

Problem: Teams is stuck in a login loop in Microsoft Edge

If you are using Microsoft Edge, or the older Internet Explorer (which is officially retired, so it’s time for a change!), you may find that your login screen for Teams is stuck in a loop. This is likely because your organization uses the Trusted Sites option and hasn’t enabled Microsoft Teams.

You can follow these steps to allow Teams. If you are blocked from the process, you may need to contact your system administrator or IT help desk for further assistance.

Step 1: Open Microsoft Edge.

Step 2: Go to Settings, then select Cookies and site permissions.

Step 3: Next, select Manage and delete cookies and site data.

Step 4: Enable Allow sites to save and read cookie data.

Step 5: Then ensure that Block third-party cookies is off. If you need to keep this setting on instead for some reason, go to step 6.

Step 6: Under the Allow section, add the following sites:

  • [*.]
  • [*.]
  • [*.]
  • [*.]
  • [*.]
  • [*.]

Problem: can’t access a Microsoft Teams OneNote notebook

If your document libraries contain more than 5,000 OneNote items, Teams may deliver this message: “One or more of the document libraries on the user or group’s OneDrive contains more than 5,000 OneNote items.” This is a known limitation of the service, and Microsoft is aware of the issue.

For the time being, you will need to reduce the number of items in OneNote below 5,000. Microsoft provides this OneNote API Diagnostic tool for counting the number of items in a specific document library, which may assist you at this time.

Error Message: Teams won’t allow you to log in to the service

If you are having Microsoft Teams issues logging in to the service, begin by ensuring that you are entering the correct login information. You may receive one of the error codes listed below if you are entering the accurate information but are still being denied access. Contact your IT department with the given error code, as the issue will need to be removed by your system administrator.

Common login error codes:

  • 0xCAA20003: Authorization problem — make sure the date and time are set up correctly.
  • 0xCAA82EE2: Request timed out — confirm you’re connected to the internet and firewalls aren’t blocking access to the service.
  • 0xCAA82EE7: Server not resolved — confirm you are connected to the internet and firewalls aren’t stopping access to the service.
  • 0xCAA20004: Request requires approval — make sure that organization is complying with Azure Active Directory configuration policies.
  • 0xCAA90018: Incorrect credentials — you are using the wrong credentials to sign in to Microsoft 365 services.
  • 0xCAA5004B: The Microsoft Teams app has encountered an unexpected issue — wait a few minutes and try again or use the web version.

Problem: notifications are not being delivered to your desktop

If you’re not receiving notifications from Microsoft Teams anymore, it may not be a glitch — the permissions just might’ve changed. Begin by checking that the Teams app has the correct settings enabled.

Open the Microsoft Teams app, click on the Three-dots icon next to your Profile photo in the top right, and choose Settings. Next, select the Notifications option. Make sure that your notifications are still on and that the permissions are what they should be. If they aren’t, adjust these settings as necessary.

Bug: Unable to send a message in Skype for Business

If you are sending a message to an individual Skype for Business account but the operation fails, there are two likely culprits. First, ensure that the recipient’s status is set to Available or another active state. Otherwise, if both users are available, ensure that both users are using Microsoft Teams to send messages. The good news is that Microsoft is aware of the problem, but the bad news is that it is still working on a fix for it.

Error message: ‘We weren’t able to connect. Sign in and we’ll try again.’

One of the most frustrating Microsoft Teams issues that you might run into with the app is the message, “We weren’t able to connect. Sign in and we’ll try again.” This notification appears when you leave the Teams app idle for too long. If you don’t notice when this banner notification pops up, you could miss out on any announcements and meeting prompts until you address it.

Sadly, restarting the app isn’t enough to fix the problem, but you can typically solve it by resetting the app’s cache. To do this, simply follow the below steps:

Step 1: Completely quit the Teams application by right-clicking the Teams icon in the system tray (next to the clock on your taskbar) and selecting Quit.

Step 2: Right-click the Start menu icon and click Run.

Step 3: In the Run window that appears, type %AppData%/Microsoft. Click OK.

Step 4: In the new window, right-click the Teams folder and select Rename.

Step 5: Type in TeamsBackup, (or any other name you may want) then hit Enter on your keyboard.

Open the Teams app and try to use it once more. You’ll likely have to reconfigure your settings from the beginning, but you should finally have this issue resolved.

Problem: Microsoft Teams keeps on freezing or shutting down

One of the most common Microsoft Teams issues is that the app will sometimes randomly freeze or shut down. Luckily, there are a few steps you can try to fix this nuisance.

Restart the app by shutting it down fully. On Windows, you can do this by accessing the Task manager through the following combination of keys: Ctrl + Alt + Del. Navigate to Task manager and choose End task. On MacOS, use this key combination instead: Command + Option + Esc. This will force-quit the app.

Make sure you’re running the latest version of Microsoft Teams before you delve into this any further. Simply click on your Profile photo when the app is currently working. You’ll find it in the top-right corner of Teams. Next, select Check for updates and download the newest version.

You can also troubleshoot or repair the app via Windows itself, but this depends on your level of access when it comes to administration rights. Start by trying to access the Settings by tapping the Windows I keys simultaneously on your keyboard. Navigate to System > Troubleshoot > Other trouble-shooters. Scroll down until you see Windows Store apps and then click Run.

Alternatively, from Windows settings, click on Apps and then Apps & features. Once you find Microsoft Teams, click on Advanced options and repair the app. This should not affect your data.

Error message: ‘You’re missing out!’ when signing into Teams

Have you received an odd error message when trying to sign in to teams? This problem affects users who run Microsoft 365 Education. Upon trying to sign in, you may encounter an error that says: “You’re missing out! Ask your admin to enable Microsoft Teams for <CompanyName>.”

Microsoft itself is aware of this problem and notes that in Microsoft 365 Education, Teams is not enabled by default. This means that your school’s system administrator will have to enable it manually. In case you’re the administrator, you can check out the step-by-step guide on how to do this on Microsoft’s official website.

Problem: Microsoft Teams asks ‘Are you still there?’

If you’re using the web version of Teams, you may have been dealing with this fairly annoying problem — frequent pop-ups that ask if you’re still there and active. Microsoft allegedly added this functionality to reduce unnecessary sync time. After all, if you’re not actively using the app, there is no need to refresh your other tabs for you. Unfortunately, this can still pop up in the middle of a meeting and log you out for no reason.

The easiest way to avoid this would be to use the proper Microsoft Teams software as opposed to the web version. Alternatively, try to minimize the amount of Teams tabs you’re running at any given time, and if you can’t, then try to mix up the web version and the app. Use the latter for meetings and other important things that you can’t afford to be logged out of.

Problem: I can’t view the full thread I searched for

For some time, Microsoft Teams had an issue where the search function only returned results for a single message or response. In other words, if you search for someone’s name, you could see the individual post with that name in it, but not the greater thread or discussion from where it occurred. Not very useful!

If this is ruining your Teams work, check for updates. This particular problem was resolved with a 4th-quarter update in 2022 so that Teams will now show the full thread when you select on your search results. If you can’t update Teams yourself, try switching to the web version of Teams and see if your searches are more comprehensive there.

Bug: Teams audio doesn’t work with Android Auto

Android Auto has a feature that allows you to tap into a web conference so you can watch and listen to it while you are driving, a great time saver when commuting. But Microsoft Teams users have encountered a bug that prevents the audio from working, so all they get is silence.

Google investigated this issue in 2022 and reported that any remaining issue is entirely on Microsoft’s side. Microsoft has yet to announce any patches addressing it specifically.

If you’re having this issue, update to the latest version of Android Auto. Some users have said that this fixed the problem for them. Otherwise, switch to audio from your phone, or audio via your car’s Bluetooth connection instead.

None of the above solutions fixed your problem?

Microsoft Teams issues certainly can get annoying, and if nothing helps, it’s time to escalate. While Microsoft Teams has its fair share of bugs that you’ll regularly experience, having more consistent problems might be something you need to get your company’s IT administrator to solve.

If you happen to be the administrator for your company, you can read through Microsoft’s support documentation, which is made readily available to anyone in need of assistance. If none of the troubleshooting options from the doc work for you, you’ll have to contact Microsoft’s technical team for hands-on help with your specific issue.
