Has anyone been able to use a .ics file to update (reschedule) an existing appointment in Outlook for Windows? I can do it with Outlook for Mac, but trying it in the Windows version fails to get rid of the old appointment instance - instead merely adding the updated appointment time/date to the old. I've been careful to make sure the UID matches in the two ICS files, and I even made sure that the SEQUENCE field incremented by 1 in the newer file. This works perfectly in Outlook for Mac, but I cannot get it to work in the Windows version. Any ideas?
