New Outlook: "Changing the ImapRemoteServerInfo is not allowed" after host migration
I'm having exactly the same issue. Whom can I reach out to at Microsoft to reset the server-side IMAP provider association / ImapRemoteServerInfo for the affected email address? I'm stuck :(
Thank you very much

I'm experiencing the same problem with stale ImapRemoteServerInfo as well. Whom could I contact to address this bug? RobertSparnaaij

If you are still logged in with the account in New Outlook, remove the account via Settings-> Accounts and choose: Remove the account from all devices. This will delete the server cache as well.
If you've got a Microsoft Account, you can open a case via that account as well to request removing the cache for address that you are having issues with.
If you are still running into issues, feel free to reach out to me via a private message with the address that needs to be reset.
Please note that this will remove the entire server-side cache of the mailbox at Microsoft. You will also lose all data from any folders which do not sync with the IMAP server of your provider.
This includes all non-mail folders such as Calendar, Contacts, Tasks and Notes, as well as the Drafts folder.

Ho there, thanks for offering to help. The address that needs the server-side reset for its IMAP configurations is mailto:email address removed for privacy reasons
Without this I will have to opt out on Microsoft 365, I need a smart e-mail client for which I am able to specify the IMAP server.
Many thanks!
