Looks like it uses IMAP. Nothing wrong with that. It is just common practive when locking down Exchange Online to tick the box in Conditional Access that disables “legacy protocols”, which includes IMAP. I’ve been using eM Client which uses EWS but doesn’t support push-mail so still on the look-out for something else.
Does thunderbird support exchange protocols or just IMAP
I use if for exchange and gmail - it’s pretty robust. Plus, they are approaching completion of their mobile app which has similar capabilities
