  • Inter-org Replication Tool from Exchange 2K3 on windows 2K3 server to exchange 2K7 on

    Hello all,

    I have a problem and I need some help. I have an old Forest with WIndows 2003 and Exchange 2003 and a new Forest with Windows 2008 with Exchange 2007 sp1. The new forest has CCR on with 2 Exchange 2007 sp1 servers. In the CCR, I have configured a Public Folder store on a new Storage space.
    I'm able to ping from Exchange 2003 the NET BIOS name of the Exchange 2007 CCR mailbox name and I have created a trust between the 2 Forests. I've also entered a secondary zone on each servers DNS, with the zone information of the other domain
    The objective is to replicate the Public Folders from Exchange 2003 to Exchange 2007.
    I have installed the Inter-org Replication tool on the Exchange 2003 server and I have created a service account with a mailbox and a new Public Folder ExchsyncSecurityFolder in each domain and I have assigned Folder Visible permissions to the new service account. On every public folder in the Exchange 2003 domain I have given this new service account owner permissions.
    When I start the exscfg.exe file, I fill-in the Publisher and Subscriber Organization fields with the proper information and on the Advanced Buttons, I enter the logon information of the service account for each domain.
    When I click n the Folder List button, I'm able to connect to the Exchange 2003 server, but not on the Exchange 2007 server. I get an error message "Unable to logon to Exchange Server using mailbox information".

    I made the service account in the Windows 2008 domain, Exchange Administrator and Local administrator on the Exchange server, but to no avail. I can connect to the Exchange server using Outlook 2003 with the service account and I verified the permissions on the Public Folders. I'm running out of ideas. Is is possible that the Inter-org Replication Tool is not compatible with Windows 2008 or that it needs special permissions to connect?

    Please give me some ideas

    Thanks in advance
