I have a number of users (max 10) who are reporting that the e-mails that they are sending/receiving are having their history cut off. They are receiving mails from Israel and China with the same problem. They are all on the same server and the server has over 600mailboxes on it. This is not being done by anyone forwarding/replying and removing the history themselves - it is just happening. Has anyone had a similar problem? What is causing this?
