Everyday Systems

I've discovered that some PM's I've drafted and sent got put in an Outbox and are still there, weeks, months, and years later, but I didn't know it. (This may account for why I didn't hear back on some of them.) Why might this happen? Does it mean I always need to check my "sent" box to see that a email actually went out? TX

Weird, I just realized that the same thing happened to me. A reply I thought I'd send Chotzinoff was in Outbox instead of sent. Hmm.
