Outlook doesn't know or care whether or not you're using wifi, so it's
definitely not a Outlook issue.
I would check for errors on your wifi connection. You could try issuing
"ping -t apple.com" from a command prompt right before you start downloading
mail on wifi. If my theory is right you should see quite a few missed
packets, especially when things hang at "16 out of 34".
Good luck with it.
