Hi, I have been trying for a day now but I can not get it to work. When I create an exception of type "DELETE" everything is fine. It works but "MODIFY" won't. I do the following: (objoutput is an EXISTING recurring master item in my outlook calendar) the code runs on the server (cdoex) ------------ Dim ExcepOut As IException Set ExcepOut = objOutput.Exceptions.Add("Modify") ExcepOut.RecurrenceID = datetimevalue ExcepOut.StartTime = datetimevalue ExcepOut.EndTime =datetimevalue ------------ The above code fails. However, this works: to create a DELETE type exception I only have to do --------- Set ExcepOut = objOutput.Exceptions.Add("Delete") ExcepOut.RecurrenceID = datetimevalue ---------- The weird part is that when I take objOutput in my debug watch, I see that his exceptions collection goes up by one when I create the DELETE exception. So the moment the [Set ExcepOut = objOutput.Exceptions.Add("Delete")] command kicks in, I see the exceptions count go up. But I don't see that with the [Set ExcepOut = objOutput.Exceptions.Add("Modify")] line. In other words, the Set won't add the exception to the exceptions collection! It's not that the exception object fails. I can debug/watch the ExcepOut object and see the starttime change from nothing to a good value as with the endtime value. Is this a cdoex bug that anyone knows of? Can't it be done with existing items but only with new items, what they do here: http://support.microsoft.com/default.aspx?id=314367 Thanks for reading this, John
Update: This started working all of a sudden. > The weird part is that when I take objOutput in my debug watch, I see that > his exceptions collection goes up by one when I create the DELETE > exception. > So the moment the [Set ExcepOut = objOutput.Exceptions.Add("Delete")] > command kicks in, I see the exceptions count go up. > But I don't see that with the [Set ExcepOut = > objOutput.Exceptions.Add("Modify")] line. > In other words, the Set won't add the exception to the exceptions > collection! So I do have the exception in the exceptions collection now both with a DELETE as a MODIFY exception. However after issuing [objOutput.datasource.save] the item in my calendar is not updated with the MODIFY exception. I only get the DELETE exception. grrr!
