I'm a delegate of BigUser. I would like to create a Distribution List
in BigUser's Contacts, and add members to that DL only from BigUser's
Contacts (my own Contacts does not contain any of the members-to-be for
this DL) while logged on to my XP Pro computer with my own account.

When I open BigUser's Contacts from within my Outlook 2003, I can
create a DL in his Contacts, but I'm unable to select from his Contacts
to add members to that DL. I can select members from my own Contacts,
but I don't have any of the members within my own Contacts. The
members-to-be exist only in BigUser's Contacts.

How can I create a DL in BigUser's Contacts and be able to select
members for that DL from BigUser's Contact list?

Both computers are running Outlook 2003 on XP Pro within an E2K domain.
The members I need for the DL are not in the GAL.

Stumped. Thanks for any suggestions.
