Have you wondered why your contact information hasn't updated in Teams yet? There is a reason for that!
Why can't I see my changes in Teams?
When your information changes, such as your display name, telephone number, manager name, title or profile photo, you most likely will not see those changes right away. Teams has a caching scheme that is designed to optimize capacity and performance.
How long will I have to wait?
Teams caches general user information for up to three days. Some data, such as display name and telephone number, can be cached up to 28 days in the client. Profile photos can be cached up to 60 days. Have patience and your changes will catch up!
