While Outlook's Rules Wizard doesn't include a rule specifically for filtering on attachments, you can create a rule that will filter on most attachments. I said "most" because it's not 100% accurate and doesn't work when the message has embedded attachments.

Begin by creating a new rule, choosing the option to "Start from a blank rule" and checking messages when they arrive.

Choose "With specific words in the message header" as the condition and enter the file name or extension, entering it in "dot extension" format: (like ".exe"), so the condition reads like this: "with '.exe' or '.zip' or '.pif' in the message header," as shown in Figure A. Complete the rule using your desired action.

Note that while this rule works on messages containing attachment types blocked by Outlook, it misses embedded attachments that are not listed by name in the message header. You also can't use this rule to save or delete attachments, only move, copy, flag or delete the message.

If you need to save or delete attachments, you'll need to use VBA or a 3rd party add-in. For more information on message processing, see "Automatic Message Processing Tools" at http://www.slipstick.com/addins/auto.htm.
