Yes, I know this may be a better question for the Outlook area, but we'll see.The subject says it all. A handful of people in our environment are getting duplicate calendar entries when they are just receiving a single meeting request. We deployed SP2 about two weeks ago. There have been no Exchange updates during this time. No Windows updates on the Exchange servers, anything.All users are in cached mode, most of the people are not delegates and do not have delegates.Has anyone heard of anything along these lines? Any ideas?

What happens if you delete and re-create their OST files?Neil Hobson, Exchange MVP

Well, actually, after gathering more facts (second hand info always needs validation!), it appears this may only really be one person having the issue. We're going to blast theprofile and OST and see how it goes. Thanks for answering.
