I'm also using Mu4e for personal email but stymied by Exchange auth for work email. I've been looking into using DavMail as an Exchange gateway, does anyone have experience with this?
I have been usong mu4e with davmail in Exchange mode for my Uni mail. It was a pain to discover how to do it but the FAQ has been updated since and it works like a charm. Deop me a mail at gmail if you wish.
