Domino Access For Outlook

Greetings,I have installed Domino Access For Outlook 6.5.3 for some users who insist on using Outlook (V.2003), and have found that they need to be granted Admin right on their local machine to be able to use Domino NAB; Otherwise name will NOT show. But users are able to see the names in the secondary address books that I have created using Directory Assistance without the local Admin rights. The issue is that our company policy prohibits giving users local Admin rights and I am wondering if others have any experience in using the DAO with more restrictive user rights and/or have any suggestions in dealing with this issue.

Thank you all in advance
