If you're experiencing issues that affect Microsoft Teams, clearing the cache on your device may help. After you clear the cache, restart Teams.
Some of the issues that could be fixed by clearing the cache:
- Users information not updated after changing their display name or email address.
- Chats messages not loading or being visible.
- Pictures sent not loading
- Teams periodically crashing
- You won't lose any user data by clearing the cache.
- Restarting Teams after you clear the cache might take longer than usual because the Teams cache files have to be rebuilt.
