Clearing the Microsoft Teams cache can solve many problems and improve overall performance. Understanding why you should do it can help you keep Teams running smoothly.

Common Issues Caused by Cache Build-Up:

1. Slow Performance: Over time, cache files accumulate and can slow down the app's performance.
2. Outdated Information: Stored cache might cause Teams to display old user profile pictures or outdated data.
3. Login Issues: Cache build-up can sometimes prevent you from logging in or cause repeated sign-in prompts.
4. Crashes and Freezes: Excessive cache can make the app unstable, leading to frequent crashes and freezes.
