Changing display name in the Admin Panel does not reflect in the Teams Windows Desktop Client

Hey guy,
I was also Facing the same issues, like i updated my display name from admin center and it was not reflecting only in Teams other office apps were fine.

Solutions:

delete teams

Clear advance history from
internet explorer (Important Step)
and from any other browser you have in you system.

Clear temps Steps:
1. %appdata%\Microsoft\Teams <-- in this location
2. Delete files from this folders : Blob_Storage , Cache, Databases, GPUCache, IndexedDB, LocalStorage, Logs, Tmp(if folder is present*).

After clearing perform below commands

Run PowerShell as an admin:
1. " Install-Module MSOnline "

2. " Connect-MsolService "

Then run the below to get the users current name
**change "garfield@odie.net" to you email**
3. " Get-MsolUser -UserPrincipalName garfield@odie.net "

Now what we need to do is we will change the display name to something temporarily and after that we will change it back to what you want.

4. so first lets run below code with a temp name
Set-MsolUser -UserPrincipalName garfield@odie.net -DisplayName "Garfield_TEMP"
<--- then enter temp name

Note: After this step please check that the temporary name is reflected in every WEB application .
(Clear history from every browser again)

5. Now we use the same (4) script to change the display name to what you want.
Set-MsolUser -UserPrincipalName garfield@odie.net -DisplayName "Garfield"

And you are done....
Now clear caches Again...

Download latest Teams and install as usual.
