Right. There used to be an API called "EWS", but that's no longer
available (at least on the servers I've dealt with). Instead, there's
a REST/JSON api that's used by the outlook web client.

There are a few email clients (that I'm aware of) that have figured
out how to use that API:

 Hiri

   <https://www.hiri.com/> (now abandoned) which stopped working for
   me yesterday.

 Webmail for OWA

   https://play.google.com/store/apps/details?id=smtb.owa Android app.

 OWL Thunderbird plug-in

   This is working nicely for me.

There is an older Thunderbird plugin (by the developers of OWL) that
used the EWS protocol (but not OWA) called ExQuilla.

I think that the protocol used by Outlook is MAPI/RPC or MAPI/HTTP. I
believe that Evolution used to be able to use that protocol, but from
what I've read it only works with very old versions of Exchange. For
newer Exchange servers, Evolution supports EWS, but the servers I've
dealt with over the past few years didn't seem to support EWS. [Though
I haven't tried for a while.]
