hi we have mac users connecting to exchange 2010 via IMAP with mac mail. For no reason the inbox mails for everyday other than today are deleted. If you check in outlook or OWA the messages can be recovered from deleted items. If we put the messages back and ensure the IMAP headers are not set to deleted, then some time later the messages get deleted. We cannot see any errors on the servers and it is extremely frustrating.
we also have a couple of outlook users who move messages to archive folders then a few hours later the messages are back in the inbox - this is also extremely frustrating!
any help or troubleshooting ideas would be appreciated
