When we still had an in-house Exchange server, it was working with Evolution with the ews plugin, but no certificate was required.
The certificate seems to be only required when using webmail. Now everything works fine using MS Outlook on a Windows machine (which I do not have and have no plan on having...).
I have no experience with EWS. I've never used Exchange and never intend to use it. That's why I recommend you ask on the Evolution list. Plenty of people there can help you with these questions. You might also look at the list archives:
