Microsoft Groups Issues and Find out how to Repair Them

Microsoft Teams was launched in 2017 as a unified communication and collaboration platform that helps companies 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. As with any software, however, things don't always go according to plan. If you're having issues with Microsoft Teams, here are some of the most common problems you can fix.

Breakdown: Teams only shows older messages and threads

If you are not getting the latest news from your co-workers or your feed seems to have frozen in time, we recommend restarting the application.

To restart Teams on Windows 10, look for the Teams icon (a small purple icon for two people) in the system tray at the bottom right of the screen. You may have to click a small arrow to expand the system tray. Once the icon is found, right click on it and select Exit. On macOS, right-click the Teams icon in your Dock, then choose Exit. Now open the application again to see if it fixed your problem.

Problem: Microphone or webcam are not working properly

If you are having problems with your webcam or microphone, first make sure that your hardware is connected incorrectly. Next, make sure your microphone and webcam are turned on during a meeting. When you join a new call, toggle switches appear for these options.

If other applications can see your webcam and microphone but Teams cannot, you may need to allow permissions on Teams. To change permissions on Windows 10, click the Windows search bar and enter webcam. Under Choose which apps can access your webcam, make sure Teams or the web browser you use to access Teams is turned on.

To change Teams' permissions on macOS, click the Apple menu icon in the upper left corner of the screen, then choose System Preferences. From here, select Security and Privacy and then Camera. You may need to click the lock icon to make changes here. Make sure Teams or the web browser you use to access Teams is turned on.

Problem: You can't create a new team in Microsoft Teams

The good news is that Microsoft is aware of the problem, but the bad news is that they are still working on a solution to it.
