Can't see new user in Global Address List
 

Just set up a new user on the domain controller, created a mailbox on the
Exchange 2000 server, however the users name doesn't show up in some (not
all) other clients Global Address List's.

For example, there are a few Outlook users who do not see her name at all in
the Global Access list, but there are also a few users who can.

This is the way we've set up new users for years, however this is the first
time we've ever experienced this problem.
