We have calendar items which are going missing. We are on exchange 2007 and oulook 2007 It seems to be related to having active sync devices connected to these mailboxes can you suggest a process for fixing this or diagnosing what is the problem/source

Can you pick one user who has the issue and reproduce the issue? Does this user use active synch? Sukh
