I had the same issue (Evolution was not able to sync any calender entry). After do some "killall -KILL evolution*" I could solve the issue.
I assume the problem could be related with "unavailable" owncloud server during start-up of (Gnome, Evolution, or what services ever). My owncloud is a test installation (Debian 64 Jessie) my Evolution is on Ubuntu 14.04 LTS (its Evolution 3.10.4). My owncloud server is not always available (especially not during startup of my Gnome system). Restarting Evolution after starting owncloud VM it seems working. Hopefully this helps others as well and maybe this could be fixed soon? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to evolution in Ubuntu. https://bugs.launchpad.net/bugs/1328381 Title: evolution "looses" write permission on remote authenticated caldav calendar intermittently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/1328381/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
