Hello.
I have a user (user A) who is a delegate to another user's (user B)
Contacts.  User B has four local distribution lists created in his Contacts
folder of his mailbox.  These distribution lists contain users from his
Contacts folder; they are external recipients.  User A can select any one of
the four DLs and send an e-mail to it.  But if she selects all four at once,
the e-mail fails to be delivered.  User B can successfully send to all four
DLs at once.  User A is running Outlook 2002 and user B is running Outlook
2003.  On the back end, both have mailboxes on Exchange 2000 SP3 boxes.

Any ideas?  Thanks.
