Found the answer to my own question but thought I should post it in case
others need it in the future.
In Outlook 2003:

Tools / Options /Preferences Tab / E-Mail Options / Advanced E-Mail Options
Third box from the bottom needs to be unchecked

Using Outlook 2003 is there a way to keep an invite in the users inbox after
they take action on it? It currently goes to the deleted items folder and I
have a user who would rather it stay in the inbox.

Thanks
