I got a call from a new customer stating that "Read e-mails" are disappearing from his "Inbox" without him deleting them. He stated that his e-mails only go back to 8.20.2013. I checked his "webmail" and the oldest e-mail is 8.20.2013.
He stated that he had older e-mails in his "Inbox" but now they are gone. Anyone experience this before?
