So the lesson here is to be less aggressive in your wording. "Did you send that e-mail at (requested point in time)? I didn't see it" "Could you tell me the title of that e-mail? My Outlook isn't finding it" "Could you resend that e-mail? I think my Outlook is having issues" Be sure to click on *Inbox* before performing searches, as otherwise they'll be limited to whatever folder you're in.
