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.

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.

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.

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.

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.
