My Outlook is frozen!!! Another damn computer question.

A work friend sent me an email with 4 jpg attachments of her granddaughter. Somehow, 13 copies of an email with the same 4 jpg attachments were queued up waiting to be received. I had to reboot my computer 5 times and reopen Outlook before they were completely received (I didn’t know how to not receive them).

So now I have 13 identical big, fat email messages that are causing Outlook to freeze everytime I open it up. I can’t even select the messages to delete them. And rest assured I haven’t opened any of the attachments. What the heck is going on? And how can I rectify it?
