IMAP and SMTP OAuth2 Authorization for Exchange
Many school and work emails use require OAuth2 authorization login. Some/many of these emails are Office365 which normally would be set up through Exchange.
Having Exchange with OAuth2 available for Geary would be nice.
It is my understanding that GOA does not have OAuth2 authorization for Exchange, but Geary does not use Evolution's Exchange (EWS) backend.
The potential work-around for using IMAP and SMTP to set up a school or work email does not seem to work since that option also does not appear to have OAuth2 as an option. This option is possible in several other linux email applications, such as Thunderbird and Kmail, so I hope/think this could work for Gnome with Geary.
So, overall, it would be nice to have OAuth2 for IMAP and SMTP, at least until the exchange option also has OAuth2 alongside working with Geary.
