Teams meeting won't start or you can't join
Teams meetings fail because Teams is out of date, your browser isn't supported, or cached junk is breaking things. Update Teams, clear your browser cache, and restart.
Teams meetings need updated software, a supported browser, and clear cached data. The join button fails because Teams or your browser is old, cached data got corrupted, or Teams is running twice on your computer.

Skip — I just want a technicianCommon mistakes to avoid
- Not fully closing Teams before clearing cache - background processes block clearing
- Only clearing browser cache without updating Teams
- Trying to join a meeting that hasn't started yet (organizer must start it first)
- Using a web browser when the Teams app would work better
Signs you need professional help
- The join button still doesn't work after updating Teams and clearing cache
- Your browser shows a message that Teams isn't supported
- You have a firewall that explicitly blocks Teams
