Outlook Account Suggestion Removal
maisondasilva Did you ever get this resolved?
Jeff_Lamb Just creating a new user or doing a clean install, other than that I still haven't figured out where this is stored!
maisondasilva Hi,
It seems that removing the synchronization of the Microsoft account for this computer (remove this device) in account settings should work, but user data and related information (including email addresses) will remain in the Microsoft cloud
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".
" we cannot set-up an account, because we see these old accounts."
Can you manually enter a new address and sync?
The old address suggestion may be overwritten during the new mailbox configuration.
