We are running Exchange Server 2003, yesterday I had two users have something strange happen to their mailboxes in Outlook 2003. One user's email account sent out mail from 2011. The other user received 168 emails follow up emails at one time. After running a Malwarebytes scan, it flagged this: PUM.Disable.SecurityCenter. My question is would this cause the strange activity with the emails?
