Common Teams Problems and Quick Fixes

Most Teams problems people run into aren't complicated, they're just annoying and not obvious how to fix. Here are the ones I get asked about most, with the fastest fix for each.

Audio or video not working in a meeting

Nine times out of ten, this is a permissions issue at the operating system level, not a Teams problem specifically. Check that Teams has permission to access your microphone and camera in your computer's system settings, not just inside Teams itself. If that's fine, the next check is the device selection inside Teams itself, click the three dots during a call and check audio settings, since it's easy to accidentally be sending audio to the wrong device, especially right after plugging in headphones or connecting to a new monitor with speakers.

Notifications not showing up

This usually comes down to notification settings either inside Teams, under Settings > Notifications, or at the operating system level blocking Teams from sending alerts at all. Check both. Also worth checking: if you've set a status like Do Not Disturb and forgotten about it, notifications get suppressed by design, which is easy to forget after a busy day.

Can't find a file someone shared in chat

Files shared directly in a one on one or group chat, without a Team or channel involved, get stored in the sender's OneDrive, in a folder called Microsoft Teams Chat Files. If you can't find something shared in a channel instead, it's in that Team's SharePoint site under the matching channel folder. Search by file name in OneDrive or SharePoint search is usually faster than trying to scroll back through chat history to find the original message.

Teams running slow or using a lot of memory

Teams is a genuinely heavy application, and running it alongside a dozen browser tabs and other apps can slow a machine down noticeably. Closing and restarting the app fixes more issues than it should, honestly. Beyond that, check if you have an unusually large number of Teams and channels you're a member of, since Teams tries to sync activity across all of them, and being in far more teams than you actually use can add real overhead.

Getting removed from a meeting unexpectedly

This is usually a network blip rather than anything Teams did wrong. Rejoin using the same link, and if it keeps happening, it's worth checking your actual internet connection stability rather than assuming it's a Teams bug. In my experience, most "Teams is broken" complaints trace back to something outside Teams entirely, a permission setting, a notification preference, or a shaky connection, once you actually dig into them.
