You do realise that the odd number releases (i.e. 3.3.x, 3.5.x, etc.)
are development releases and not meant for production use?

As a user of Evolution EWS (i.e. not a developer) I have found that
finding the required URL is a bit of a dark art.  It doesn't necessarily
follow that the URL you use is the same as the one for logging in to
OWA.  This is almost certainly not the fault of Evolution EWS, but more
the arcane and obscure setup of complex Exchange systems.  For instance
the Exchange 2010 server I use has a web access URL of
https://owa.host.domain.uk (real names changed to protect the guilty),
whereas the EWS URL is https://host.domain.uk/ews/exchange.asmx

And then there's the username required - my external email address is of
the form 'first last unit domain uk', I login to the OWA interface with
my "real" username of, say, 'unmame', but the EWS config requires my
username there to be 'uname host domain uk'.  Again, I don't think this
is really a failing of Evolution EWS, but more a symptom of how Exchange
is setup.

All I can say is that once it's setup correctly, it works well.  All I
need now is shared calendar access ...
