I manage a company with 200 users, all of them having IMAP mail in a cloud based hosting (not on premise); now I want to migrate some of those users on Microsoft 365, keeping the most of them on IMAP; is it possible? How can I let the dns failover to IMAP if not finding Microsoft 365 address?
Another question regarding free Microsoft Teams account, if I put my domain as a Microsoft corporate account, they are going to stop to work. Do you think is it possible to keep those free accounts and in the meanwhile to get corporate Microsoft Team for just some of the addresses?
Thank you very much
