Here are some of the most frequently encountered issues you might run into while using Microsoft Teams and the steps to take to fix them:
Check that the correct audio device is selected in Teams. After ensuring that your microphone is not muted or disabled in the settings, you can test your microphone and speakers by using the Windows’ Sound Settings (accessible from the Start Menu or by right-clicking on the speaker icon in the system tray) or by using the Device Settings in the Teams app. Try restarting the device or unplugging and plugging the audio jack.
Check that the network connection is stable and that you have sufficient bandwidth. You can check your connection speed using an online speed test at speedtest.net. If possible, try using a wired network connection instead of Wi-Fi. Close any other applications that might be slowing down your PC.
Check that the device is connected to the display or projector and that it is configured as an extended display (Windows Key + P.) Ensure that the latest version of Teams is installed and try restarting the device.
Check that the device is signed in to Teams and that the meeting invitation is valid. Ensure that the network connection is stable and that the bandwidth is sufficient. You can clear your cache to make sure that is not causing issues. Go to the Profile Picture > Settings > Applications > Microsoft Teams > Clear Cache in the Teams app. Try restarting the device or signing out and signing back into Teams. The issue could be with the Teams service itself. You can check on that here.
Check that the audio device is set up correctly and that the microphone is not muted. Ensure that the network connection is stable and that the bandwidth is sufficient. Try restarting the device or unplugging and plugging the audio jack.
Check that the camera is connected and enabled in Teams. Ensure that the latest version of Teams is installed and try restarting the device. If the issue persists, check that the camera is not being used by another application.
Check that the device is connected to the network and that the file or document is not corrupted. Ensure that the latest version of Teams is installed and try restarting the device. If the issue persists, try accessing the file or document from another device.
