halo everyone, i'd tried to replicate a public folder from ex5.5(domain A ) to ex2k (domain B)using active directory connector but it didn't worked. the message error was something like: Unable to create an intra-organizational connection aggrement using the specified exchange 5.5 server. The exchange 5.5 organization is different from the exchange 2000 Connection Agreements to different Exchange 5.5 organizations must be created as inter-organizational Conection Agreements. Select the inter-organizational Connection Agreement checkbox on the Advanced page before continuing ID no : c103aa39 Microsoft Active Directory Connector Management but in the advanced tab, the checkbox is highligted in gray (not choosable) is it possible to replicate public folder from one domain to another domain(ex 5.5 to ex2000)? thanx in advance
