Grant, without knowing your particular specifics I'll take a stab at trying to help as Microsoft seems to... well, they're not anwering.
You may have the "Outbox" section already opened and visible. With email open, look on the left-hand side and you'll see a pane that should start with "Quick Views" and then a list of your current email accounts you have the program to check. At the very
bottom, just before the tiny words "Add email account" it should say "Outbox". Highlight that by clicking on it and you should see your problem email on the right-hand preview pane.
If this doesn't help, let me know which version you are using and send a screenshot of the program open. Please edit out anything personal before sending. You can send it to my sockpuppet account batbubba at ymail dot com.
