Why Cleaning Out the Teams Cache Sometimes Helps to Fix Clients

Microsoft Teams has a poor reputation for performance. People often suggest clearing the Teams cache is a good way to fix a variety of problems. That might be the case because hard experience proves that clearing the cache often helps.

Maybe no clear answer will emerge until we have a Teams 2.0 client, and that’s likely to come with its own oddities.
