There are several why your messages end up in the Junk E-mail filter.

As of Outlook 2007 SP2 there is an Infobar notification above the message which tells you whether the message has been filtered out by the Outlook Junk E-mail filter or by something else.

Filtered By Outlook
If the message has been filtered out by Outlook, then the Infobar will contain the following text;
”This message was marked as spam using the Outlook Junk E-mail filter.”
When you see this message, you’ll need to troubleshoot your Junk E-mail settings in Outlook. Make sure you have the latest updates installed and even try turning off the Junk E-mail filter to find out where the messages end up now.





Filtered by another scanner

If the message has been filtered out by another scanner, then the Infobar will contain the following text;
”This message was marked as spam using a junk filter other than the Outlook Junk E-mail filter.”
When you see this message, you’ll need to troubleshoot the virus scanner or Junk E-mail filter that is included in your Security Suite or contact your ISP or mail administrator and have him/her check the virus scanner and/or Junk E-mail filter settings on the mail server (for instance; adjust the SCL threshold when working with Exchange).



Moved by an Outlook rule or moved manually

If a message has been filtered out via a rule or has been moved to the Junk E-mail folder manually, then the Infobar will not indicate a reason why the message sits in the Junk E-mail folder

When you see this message, you’ll need to check if you don’t have any rules configured which move messages to the Junk E-mail folder.
