Teams - renamed user still displayed with old name

[Tom733]

I renamed user in 365 admin centre, the new name is correctly displayed in Teams admin centre but - in the Teams, the old name is still used everywhere even for new posts, when adding to new team etc. Any help?

Did you change display name too?

[#3]

Yes I did...

@Tom733 I'm having the same issue with one account. Did you ever find a resolution?

@Tom733 

I am having same exact issue. Changed Name, DisplayName properties in OnPrem AD. Everywhere else the new name show up correctly, NOT just in Teams for few users.

I learned two things:

1. It looks a long time (a week may be) to show up the changed named in Teams

2. Users who already have chatted with the user who changed name, their HISTORY will show the old name. If they start a new chat, it will show new name.  Supposedly clearing the Teams cache should resolve the issue.
