mutt VS cyrus-sasl-xoauth2

Work's recent move of email from gmail to Office365 caused an authentication problem for a while, then I came across https://github.com/muttmua/mutt/blob/master/contrib/mutt_oauth2.py which can be configured in =.mbsyncrc= as a password command:

Download this file and save it to some location. You need to edit it with a secret and id. I'd suggest just getting those from thunderbird's or you can make your own.

At first, to simplify the procedure, I started with the credentials of an open source email client. I then used the tool mutt_oauth2.py (which is a streamlined version of google-api-python-client).

no you need to install both cyrus-sasl and some form or another of xoauth, such as https://github.com/moriyoshi/cyrus-sasl-xoauth2. If you're on a mac you should look at this issue: https://github.com/moriyoshi/cyrus-sasl-xoauth2/issues/9

Unfortunate things 2: it seems that even once you have cyrus-sasl installed, there might not be a standard, widely-distributed XOAUTH2 plugin. The one I found referenced the most often and ended up installing myself was here. It took me a lot of fiddling with the configure.ac file to get it to install the plugin to /usr/local/lib instead of /usr/lib, because, again, Apple does not want me to do things the default Linux way, because of reasons.
