[Evolution-users] [EWS] Posing as an Outlook client

Heya all,

I am on Evolution 3.56.2 (no flatpak). My uni's Azure server has not added
non-Outlook clients to its list of authorized clients. Is it possible to have
Evolution pose as an Outlook client during the Oauth2 authentication to a
Microsoft Exchange Server? My idea was to do so from the "Overwrite Office365
Oauth2 settings". For example, the Outlook Web App has application ID
9199bf20-a13f-4107-85dc-02114787ef48, but because it is a web app, replacing
that parameter alone wouldn't work. I would also need to figure out the
redirect-uri parameter at the very least.

I have no access to a Windows machine, so I have no way to reverse-engineer the
HTTP request desktop Outlook performs.

Best,
Stefano
