[Evolution] Evolution EWS stpped working after Exchange migration from 2013 to 2016

[Eduardo Trápani <etrapani gmail com>]

Hi,

I was using evolution-ews without problems, until the server was
migrated to Exchange 2016.

Just in case, I did:

$ rm -rf .config/evolution
$ rm -rf .cache/evolution
$ CAMEL_DEBUG="all" LANG=en_US.UTF8 evolution

[I then recreated the ews account, got the OAB URL, then closed and
restarted, because no messages were shown]

Does anybody know if there is a workaround or something I can try? I
have no control over the server, so I cannot ask them to use IMAP+ or
turn on some sort of compatibility. All I know is that they have
migrated to Exchange 2016.
