@ericsfraga @true_mxp It's easyer to config OAuth2 with the davmail in the middle. I configured with out davmail and it was difficult because I had not idea of OAuth2. And you'll need an Azure Enterprise APP key. With Davmail you dont need any of this and mbsync syncro thru imap proxy davmail.

@Cnoceda @ericsfraga Yes, exactly, this was my idea as well. Authentication works, and the IMAP proxy server works *in principle*, too. But *in practice*, I couldn’t get #mbsync to reliably work with #davmail’s IMAP proxy; some messages were never synchronized.
