        Hi,
I vaguely recall something similar with IMAP, but nothing with EWS. The
EWS works differently than IMAP. When you mark message as read the
account saves the change within a minute or so on its own. You can even
select a different folder, which will save the changes immediately.
When you return back to the folder it is updated with the content on
the server. I do not see a reason why the save would fail. You might
run Evolution from a terminal and check its output, in case there would
be printed anything related. You can also enable EWS debugging with:

   $ EWS_DEBUG=2 evolution

to see what Evolution sends to the server and what the server returns.
The log shows raw communication, which is not share-able in public
without sanitizing, because it contains a lot of private information.
You can limit the interesting parts of the log when you "mark" a place
just before you mark message as read and move to a different folder;
then only the new content since that mark until you return back to the
folder and see the previously marked message as read to be unread is
interesting.

One problem with EWS log is also that some parts can be encoded, thus
it's not obvious that the encoded part contains private information,
aka the private information is not always shown in the plain text. I
mean, if you'll be sharing the log, then be careful. If unsure, then
send the log only to me for a quick observation, just reference this
thread, thus I won't overlook your mail in my spam folder.

        Bye,
        Milan
