Syncing back from caldav to org creates the following. Original in org-mode TODO Neuer Termin mit Foo und Bar <2013-03-06 Wed 10:00-10:00> :PROPERTIES: :ID: 8a9651c0-faee-4416-afa6-979e328a3d15 :END: Synching to caldav work flawless In SOGo I can find TODO Neuer Termin mit Foo und Bar *Please note there is a space at the end of the line. Not sure if this might trouble* Now I make a tiny change e.g. change the length of the appointment from within SOGo and sync back I get TODO TODO Neuer Termin mit Foo und Bar r<2013-03-06 Wed 10:00-11:00> :PROPERTIES: :ID: 8a9651c0-faee-4416-afa6-979e328a3d15 :END: As you can see the TODO doubled and the last character of the title is repeated. I guess its simply some regexp, which needs some finetuning. All the best and thanks a lot Torsten CC. Did you had a chance to look into calfw and think about how to make use of it for org-caldav?
