Samsung Email 6.1.51.1, Android 10, Samsung S9, syncing with exchange server - Email stops syncing because the domain suffix drops from the "Domain/UserName" in the email settings. When I add a new account it suggests the correct Domain/UserName as "/name@domain.com". Within two weeks it randomly changes to "/name" dropping the domain name so it will no longer sync. The app will not allow me to edit the "Domain/Username" so the account has to be deleted and set up as a new account.
