Deleted In our case, we have multiple accounts due to an acquisition. The source tenant's emails were added side-by-side with the destination tenant. Then we cut-over the domain and changed the user's destination mailboxes primary SMTP to match what they had in the source tenant. Now the source tenant UPNs are @sourcecompany.onmicrosoft.com. Now in "New Outlook", we cannot set-up an account, because we see these old accounts. Two of which are @sourcecompany.com. I suspect that one of them is now the user's active mailbox in the target tenant with the primary SMTP and the duplicate is a "ghost" of the old connection to the source tenant, which no-longer works. 

 

For the life of me, I cannot find anywhere to remove these accounts. They are present on about a hundred Windows PCs. None of these people can use "New Outlook".

Deleting the users' Windows profiles and making them set-up new ones does solve the problem, but you can imagine how damaging that is to the user's productivity to essentially set-up a new computer.
