I have two domains in the same Forest. They both have Exchange 2000 Ent. w/ SP3. Parent Domain A - UserA Child Domain B - UserB They want to share and access each other's Calendar. But they can't. When UserA tries to open UserB's Calendar the dialogue is: "Unable to display the folder. The information store could not be opened". They each other gave permission "Reviewer". Please shed some light on this. Many Thanks. - Symyuser
