I have a user that constantly complains from missing emails (he uses deleted items folder for storing emails, which is complete nightmare). However I am sure that one of the devices he uses does this. I know that he has two mobile devices and one iPad. In the office in use is Outlook 2007. How can I track if any other device is connecting to his mailbox, and deleting this emails?
The configuration is SBS 2008 and exchange 2007.
