first, I want to thank everybody who contributes to Evolution, it is the software I use most and it is very well done. Unfortunately, after years of stable operation, I got now a problem:
I am connected to an exchange server via EWS. Suddenly, the downsync (appointments written by my secretary sharing my calender via OWS) did not sync anymore. Upsyncs (appointments written by me in Evolution) work, they show up e.g. when she or I start the OWS calendar.
Even worse, this works and does not work intermittently, I did not find any systematics. Reinstalling., removing cache et. did not help.
When I start Evolution from the command line, there are no particular messages when I try to sync (refresh) the EWS calendar. When I try to import a local .ics file into the EWS calendar, I get the following warning.
(evolution:5837): GLib-GIO-WARNING **: 09:11:57.040: Your application did not unregister from D-Bus before destruction. Consider using g_application_run().
When I run EWS_DEBUG=2 evolution >& logfile from the command line, I find again this in the logfile:
(evolution:6365): GLib-GIO-WARNING **: 09:14:19.152: Your application did not unregister from D-Bus before destruction. Consider using g_application_run().
Furthermore, the only error message I see in the logfile is repeatedly this one:
< HTTP/1.1 401 Unauthorized

Any help is greatly appreciated.
