Hi Maha, How can I create mailboxes in Exchange 2003 directly without using Exchange 5.5. Is it through Microsoft Excel through which users can be created in Exchange 2003 or is there any other way out for this. As far as current setup is concerned My Global Catalog Server is Windows 2000 Server and Exchange 2003 Standard Edition is installed on Windows 2003 Standard Edition. Organization name in Exchange is moduleone. Name of Exchange 2003 server is "exchsrvr2003" and exchange 5.5 server name is "exchsrvr". This is the only organization in Exchange 2003. Please help.

We have one Global Catalog Server. This week we have changed the domain controller role of a machine to Global Catalog & Exchange 2003 it is taking the new machine as Global Catalog server. But when I create a new user in Active Directory and I go on to create its mailbox in Exchange 5.5 it says no mapping between SID found. Even the user is replicated from Global catalog server to other domain controller. Is exchange 5.5 is looking for previous Global catalog server which is now working as a domain controller now. When I try to move mailbox from Exchange 5.5 to Exchange 2003 it gives error in event log with error id "8183 source "MSADC" and "8270" soruce "MSADC" How do I correct this problem? Or how can I create mailboxes Exchange 2003 without involving Exchange 5.5 in the process.
