The problem is that my Contacts are stored in an Exchange 2007 Server which needs authentication on login.
But the Auth data is not passed through DavMail to Exchange. (Checked with WireShark.)
Is there a fix to get Evolution and DavMail Combo to send the login to the Exchange?
Thunderbird/DavMail Contacts do work.
The settings in Evolution and DavMail are like mentioned here.
