Clearing Teams Cache
When we’re experiencing persistent issues with Teams, clearing the cache can often provide a fix. Cache stores temporary data to help Teams run efficiently. However, over time, this data can become corrupted and lead to errors. Here’s a quick way to clear Teams cache:

Clearing the cache effectively gives Teams a fresh start, potentially clearing up any errors resulting from corrupted cache files. After doing this, we can try logging in again to see if the issue is resolved. If not, we may need to delve deeper into other potential fixes or contact support for further assistance.
