I have a user who, after changing their SAM account name locally in a hybrid environment, can no longer upload files in teams chats. The error he receives is simply "something went wrong while sharing. Let's try again". The user was able to log into their onedrive and can chat normally in teams. They logged into the teams web application and they get the same error there. I'm guessing this is a permission issue of some kind but I can't find any real info on this issue. I ran the self-diagnostic tool in the admin center and it claimed there were no found issues with the user account.

The issue did end up being solved with a second password change by the user and a bit of time.
Now I'm facing the same problem. Did you change everyone's password? or only the problematic account And after changing the code, how long do I have to wait?
We only changed the password of the problem account. It took a few days for the problems to go away though so it may not have been the password reset that did it, but that is the only change we made.
Hey Suganya, my client is unable to send files in teams in private chats since the UPN swapped Friday
