Set-MSOLUserPrincipalName -UserPrincipalName user@domain.com -NewUserPrincipalName user@domain.onmicrosoft.com

And after that run the command again to change the UPN again to the desired domain:

Set-MSOLUserPrincipalName -UserPrincipalName user@domain.onmicrosoft.com -NewUserPrincipalName user@domain2.com
