You'll want to start with a blank rule that checks messages when they arrive.

In Step 1: Select Condition(s), you can leave everything unchecked which will allow the rule to apply to all email. Alternatively you can opt for the "received in a specific date span" if you have a time frame in which the auto reply should occur. Make sure "on this machine only" is not checked so the rule will run even if Outlook is not open.

In Step 2: Select action(s), you want to pick "have server reply using a specific message". When you click on the specific message details, Outlook will open a New Message window. Fill out your desired subject and message body, and click Save & Close.

Click Finish and you're all set. Just turn the rule on when you want to apply.
