I have a mailbox that is configured to forward messages to multiple mailboxes, I accomplish this by using rules. I configure the rules using OWA. For some reason, the rules are disappearing. I don't have an exact time pattern, but I'm guessing after 24 hours the rules will disappear. Any ideas? If it's someone on the network that is removing them for whatever reason, is it possible to get a history of changes made to a mailbox (Powershell script)? Thank you for your time.
