Outlook 2010 Auto Reply with attachment

I'm using Outlook 2007, but I'll bet it's the same in 2010.

Look at:
Tools
Rules and Alerts
E-Mail Rules
New Rule
Check Messages when they Arrive
next
Specific Words in the subject
Click on Specific Words in the bottom window and specify the words
Next
reply using a specific message
Click on Specific Message in the bottom window and specify the message and attachment

The rest should be pretty straightforward.

I usually specify that it should quit checking rules once one is used.

I have followed your suggestions down to reply.  In 2010, the only reply option is "reply using a specific template."  To create my template, and this is where I may have erred, I opened a new message, made an entry in the subject, the message body, and added my attachment.  I left the name (receiver) blank since it is a reply and I asseme Outlook will fill that in.  
When a rest message is received, Outlook prepares the response but does not fill in the Name so the message goes to the Outbox or Drafts folder and can't go any further without a receipient.

Create the template from within the rule - not as a separate task.

The only reply option I can find in O2010 is "reply using a specific template".  Specific template is the variable and when you click on it, the options are to browse to "Standard Template" (there are none and no option to enter) or "User Templates in File System" which only browses to templates I have already created.  I cannot find a way to create a template within the rule.

OK - this may be a difference with Exchange-connected Outlook

Could the issue be the attachment? Is it possible to make an automatic reply without an attachment?

Good suggestion

I'm experiencing the same problem:

"Outlook prepares the response but does not fill in the Name so the message goes to the Outbox or Drafts folder and can't go any further without a receipient."

I'm not trying to send with any attachments. Any ideas?

Thx
