Somehow looks like only the oldest (say 200) entries are duplicated. As a result, my entries from last year are 3x in Horde calendar, those from spring this year are 2x in the calendar and the current entries are fine (just a single entry per event) Tue, 26 Jul 2011 09:45:40 +0000 https://bugs.horde.org/ticket/10385#t66563 Please read http://wiki.horde.org/SyncMLProblemReport and follow the steps to generate complete SyncML debugging information.

Here is what I did: - I created a new calendar in horde and made this the only one to be synced - then I started a sync (using "refresh from server") to wipe my phone calendar - after that, I had just one entry in both my phone and the horde calendar - next I created an event on my phone and changed the sync type to "slow sync" (btw. I tried "normal sync" before, but that did not work) - after the sync, I had two events on my phone, but three in the horde calendar Attached are the files from /tmp/sync, as well as the horde.log. I had set up the error_log in my php.ini, but this file was not created. Tue, 26 Jul 2011 17:09:56 +0000 https://bugs.horde.org/ticket/10385#t66581 Your client is broken. It confirms the adding of the server event with a Map response, yet it sends another Add message for exactly the same event during the next synchronization. Tue, 26 Jul 2011 23:46:08 +0000 https://bugs.horde.org/ticket/10385#t66596 After purging syncevolution on my phone, clearing all sync-caches and configs and rebuilding the config from scratch, this error disappeared. So it was actually a misconfiguration/bug on my phone. You were absolutely correct with you analysis. Thanks for your help and sorry for wasting your time.
