User not seen in GAL but mailing worksLocked
We have two sites in our exchange organisation, with Site1 running Exchange 2000 and Site running Exchange 5.5
The problem when the users from Excahnage 2000 site try to resolve one specific user belonging to Site2, they are failing. They are able to resolve the other users of Site2. The same user name can be resolved within Site2.
What is the problem ?
