Thanks for a bug report. The first backtrace shows semi-finished authentication for your EWS account, but I do not see there any ews thread, which might be removed on connection failure probably, thus it seems like the authentication for the EWS account will never get reply on it. I thought this is fixed with evolution-ews-3.4.3-1.14. The second backtrace is only a bit longer, main thread is blocked by a request to calendar factory - you might select message with a meeting invitation. Finally the last backtrace is almost the same as the first backtrace. Let's move with this under bug #843684. *** This bug has been marked as a duplicate of bug 843684 ***
