The Issue
My company has created an archive policy that is applied to all mailboxes. This archive policy causes any items older than 180 days to be moved to the archive mailbox. This policy has worked well up until recently. One of our executives contacted the Service Desk because some of his tasks were missing. After some digging, we discovered that the tasks were not missing. Having been created more than 180 days before, they had been moved to the archive mailbox.
