Safely using the Preview Pane in Outlook.

You CAN have the preview pane active in Microsoft Outlook without auto invoking all of the HTML spam you get.

To do this, just make a folder in your inbox that has the preview pane turned off. Then when HTML mail arrives, move it into that folder. You can also turn onthe auto-preview line that shows the first three text line for the email. This really helps cut down the spam that include refences to websites. That kind of email usually has your email address embedded in it (in code) so that the spammer can just tell when it has reached a live destination. Use this method for a few months and your name will drop off many of the spam lists.

To move only the HTML based email over to the ‘Suspect’ folder, create a rule that looks like this (leave a comment if you want more details than what is shown here):

Apply this rule after the message arrives
through the YOURACCOUNT@HERE.COM account
  and with ‘multipart/alternative’ or ‘multipart/related’ in the message header
move it to the SOME FOLDER WITH PREVIEW PANE TURNED OFF HERE folder
  and stop processing more rules
