I have been using Outlook 2003 for a long time and never had this problem. Recently I've started using Outlook 2007 and many important e-mails that are not junk mail end up in my junk box.
I have tried adding exception to each one but I have to do this each time. Each time I receive e-mail from someone who is not present in my contact list it ends up in junk mail. How do I stop Outlook sending my mails to junk?
