So with an IMAP account, Outlook actually connects to MS servers, then MS servers connect to the IMAP provider and act as the middleman.

Is it still the case? At that time it was a big deal, including my job IT blocking access of Outlook mobile to our on-premises servers, but I think MS was announcing that they were working to remove this man in the middle approach.
