Mark,

I already did what you suggest:

The user is indeed visible in the All Users list.

The problem is that I want, for exemple, to open the Mailbox of this user A
from the Outlook Client of user B (after having set the proper rights and
properties in the good tabs of the "User A" ADUC account).
User A is not visible in the Global Address List as I said in the first
post, but visible in the All Users list. But when I choose it, I get an
error : "This object doesn't exist" or something similar.

I have the same answer if I type the full address mail of this User A.

Regards

Nicolas

When you drill down in the Address Lists and look in the All Users, is
he there?
If you were to type his name into the To: field and then do Check
Name, what happens, does the name underline or does it not resolve?
