*** Bug 837022 has been marked as a duplicate of this bug. ***
Thanks for a bug report. I think this is just variation of bug #836740, this time in evolution. The common part is that the client tries to authenticate, but ews either doesn't return correct authentication error (which seems to be it, according to bug #836941), or the authentication code ignores the error. The later was fixed recently, thus I think this is rather bug #836941. I'm marking this as a duplicate of bug #836740, because the connection between these is more clear. *** This bug has been marked as a duplicate of bug 836740 ***
