Hi Peter, hi Giovanni, I had the same problem with having to register an "app" to access my emails (but with neomutt, not Emacs).
Instead, I ended up "borrowing" Thunderbird's client key and secret, which has worked fine so far. Maybe I'm being a bit paranoid, but I don't want to post the literal key here. You can copy it from mailnews/base/src/OAuth2Providers.jsm in Thunderbird's source tree (look for "login.microsoftonline.com" in the kIssuers variable near line 140). Send me an email privately if you can't find it. I hope that helps, Timo On Tue, Jan 24, 2023 at 07:41:51AM -0500, Peter Polidoro wrote: > > Giovanni Biscuolo <g...@xelera.eu> writes: > > > have you solved your problem? > > No, I hate to admit that I have given up in frustration. > > My work email unfortunately uses office365.
