	Hi,
the application ID is correct, it won't show "GNOME Evolution"
otherwise. They really mean it, the administrators need to allow
Evolution first, otherwise the users of the organization (tenant)
cannot use it.

When you go to the account Properties->Receiving Email, there is a
"Help..." link, which brings you to the wiki page about the Exchange
OAuth2 settings, where you can find a section with three different
application IDs. Try the third, just pay attention to what other values
apart of the app ID you should change to make it work. This app ID may
or may not work, it depends how much strict they are.

When you change it, it gets tricky to make it used (I'm sorry,
evolution and evolution-data-server are rather dull in this area),
similar to trigger the re-authentication. Run from a terminal:

   evolution --force-shutdown

and then open seahorse and in the Passwords section find the one for
the Microsoft 365 account, it should have in the name something like:

   Microsoft365[you at hotmail.com]

and delete it. Then run Evolution and you'll be prompted for the
credentials.

	Bye,
