|"Also it doesnt mean that all my emails will go back in my aol inbox...does it" As I already said, if the emails were removed from the server, then stopping using Outlook will not put them back up there. Only new ones will be delivered to your AOL mailbox.|
"I didnt even send emails to saying they received emails from my aol addy withnothing in them!!" That has nothing to do with Outlook. Your email address is probably being spoofed, which is why people think emails are coming from you when they aren't.
If you want to stop using Outlook, and still want all those emails up on the AOL server, then you'll have to send/forward them to your aol account.
I think you're jumping the gun. If you have mail set to leave it on the server, then it will leave the mail on the AOL server. I'd recommend sticking with Outlook.
