I recall some oddity since updating samba to 4.5.0 or something
It provides ntlm_auth (here at /usr/bin/ntlm_auth), which is used by
libsoup, which evolution-ews uses to connect to the server. The file
a helper and the evolution-ews can work also without it. Try to rename
it, whether anything changes. I would also verify that a correct
authentication method is setup in the evolution-ews account

I guess that was the upgrade for fixing the “badlock” vulnerability in
Samba, which changed the authentication code quite a lot.
FWIW, I found that such fix made evolution-ews unable to login with
non-ANSI passwords (which used to be possible when using NTLM
authentication), but I didn't investigate it.
Milan, I guess you won't have a basic cli program with an evolution-ews
stub which simply authenticates against Exchange, would you?
