I have one user the will receive every email twice. First email is normal the second comes as an attachment. They show up in Outlook and OWA the same way so I don't think its an Outlook issue. The emails so up at the same time. I've looked at the server side rules for the mailbox and there is only one the default clear categories.
Exchange server 2010 fully patched. Only one Exchange server in the org. Any help would be appreciated.
