BB Bold :: 9900 Receives Emails Then They Disappear

So my boss tossed his phone at me chewing me out because it "doesn't work". I cycle the power and ask what's wrong, his phone will display that a new email has arrived it will download and it will read but once it is read the email disappears never to be found on the phone again. The message is still usable on the computer but for the phone it's 1 and done. I checked out the email options on both the computer and the phone and there's no auto archive to a pst or anything. I really don't want to reset to default because I'm sure there's "important" stuff on the phone that will lead to working over the weekend. The phone also will display missed calls (legit missed calls) but won't show who or when the call was missed.
