I have an Exchange 2010 email account with 3 mailboxes hosted by Network Solutions. Outlook 2010 is installed on the clients. Outlook shows two folders ("Junk" and "Junk E-mail) for junk email. Some good email is getting sent to the "Junk" folder. I already disabled the Outlook spam filter (it was sending spam to the "Junk E-mail" folder). In addition, the hosted exchange account includes MessageLabs (Symantec) off-site spam filtering which sends an email notifying the user whenever spam email is detected, but doesn't move spam to any folder. I don't have any rules set up.
My main question is this:
What program is identifying good emails as spam, and sending it to the "Junk" folder.
