Does Microsoft already have solution on this? 

After a user's domain was change to every file that was uploaded in Teams Chat cannot be access by those users.

@ljlaureta Not that I've heard of, I assume they changed the users UPN somehow, which causes the URL to their OneDrive to change, hence breaking links.

The answer is to not change UPNs, too much impact. Doesn't stop the display name and email addresses being changed.

I feel your pain. I truly disliked my company employees having an onmicrosoft email account in addition to our corporate emails, so I switched the UPNs to the corporate emails and it completely derailed my company’s internal comms. It’s been this way for close to a month and all of Teams tech support are in Africa, incredibly hard to understand their English and really for the countless hours I’ve spent on the phone with them, it hasn’t helped. Microsoft forces you to have outlook email if you register for Teams.

WARNING: IF YOU USE GMAIL, DO NOT SWITCH TEAMS UPNs TO THAT EMAIL, ONEDRIVE STOPS WORKING, COLLEAGUES ARE FORCED TO SIGN UP FOR THE MICROSOFT AUTHENTICATION APP AND HAVE MAJOR LOGIN ISSUES, AND YOUR CALENDER INVITES WILL NO LONGER GO TO THEM!!!
