Outlook 2007 problems

Something is very wrong with my OUTLOOK - all of incoming messages are going into one of my folders (can't find a rule that would make that happen). Someone said he received 65 emails from me yesterday (I didn't send him 65 yesterday) but... when I went to log out last night there were messages in my OUTBOX that should have gone out days before - HELP????!!!! I just heard from someone else that they received a bunch from me that I didn't send and many are repeats - things are also going to JUNK that never used to go to JUNK. I don't want to lose my data. Please help me. Thank you in advance.

you have TWO separate issues
incoming email being classified as JUNK
correspondents receiving email that 'appears' to be coming from you

On (2), go to your Accounts and tweek the email user-id to make in invalid.
Also make sure you SAVE a copy of all outgoing email.
This will stop your ability to send and you can then watch to see if your correspondents STILL have bogus email.
If they do, then your email address has been hijacked and you will need to get a new one -- sorry.

On (1), see this MS Tech Note (http://technet.microsoft.com/en-us/library/cc179183.aspx)

Thanks for your help man. Actually, this wasn't my machine so I went over and ran Malwarebytes and found 255 infections. Cleaned it all out and this resolved my issues. Thanks again.
