Interorg Replication tool in mixed forest Environment RRS feed

  • Question

  • Hi,

    I would like to know if Interorg Replication tool is supported in the mixed exchange environment. Below are the details of the setup. Once the setup is done then we will be migrating users from Forest B to forest A

    Forest A - Exchange 2003 and Exchange 2010

    Forest B - Exchange 2007

    Please comment

    Regards,

    Krishna

  • The above link from ECSWorld should get you sorted Krishna.

    The one thing I do not see discussed though is the versions of Outlook.  Please ensure that you know about the different behaviours.  E.g.

    Outlook 2003 - Only ever uses FB Public Folder.  No Availability web services calls

    Outlook 2007 - needs GALSync (contacts pointing to user that exists on the other forest)

    Outlook 2010 - GALSync not required, but saves users making typos

    And you will also require Outlook Anywhere (OA) to be enabled

    http://technet.microsoft.com/en-us/library/bb125182(EXCHG.80).aspx

    Microsoft Exchange Server 2007 Service Pack 3 (SP3) Update Rollup 6 uses the external URL for Exchange Web Services to connect to the target forest. The external URL for Exchange Web Services cannot be returned by the Autodiscover service if Outlook Anywhere is not enabled in the target forest. In this case, the cross-forest lookup fails.
    To work around this issue, enable  Anywhere in the target forest, and then verify that the external URL for Exchange Web Services is configured correctly.

    e.g.

    Set-WebServicesVirtualDirectory -identity “server_name\EWS (Default Web Site)” -ExternalURL https://mail.contoso.com/ews/Exchange.asmx

    A lot depends on the client software. Outlook 2003 isn't going to use
    anything except Public Folders to manage F/B information.
     
    I doubt that cross-forest availability is going to work with Exchange
    2003 -- I don't think that web services existed in that release.

  • Hi Krishna,

    Yes, you need to use interorg tool to replicate the data to the Exchange 2007 forest public folder hierarchy, if you still use Outlook 2003 client. But if all the users use Outlook 2007 now, you don't have to use it to replicate the free/busy data to Exchange 2007 forest public folder hierarchy.

    Legacy Outlook clients or users who have mailboxes homed on earlier versions of Exchange cannot use the Availability service, they cannot retrieve free/busy information for users outside their forest unless the information that is stored in public folders is replicated between the forests.

    Therefore, if you are running Office Outlook 2003 or an earlier version, you must use the Microsoft Exchange Inter-Organization Replication tool to synchronize free/busy data across multiple forests.

    What does Exchange 2007 Availability Service do?

  • Hi ,

    Yes, you can use it in the mixed exchange environment.

    And please note the requirements when it runs in the mixed exchange environment.

    The detail information, please refer to the article Rich Matheisen mentioned.

  • Thanks for the response

    Can we have cross forest availability service configured between forest A(Exchange 2010 and it also has exchagne 2003 in the environment ) and forest B(Exchange 2007).

  • Hi Krishna,

    See http://blogs.technet.com/b/exchange/archive/2011/03/04/how-to-configure-the-availability-service-for-cross-forest-topologies.aspx this explains how it works between 2007 and 2010 forests. I am not hundred percent sure, but I would expect that it will also work if you have a mixed environment 2003/2010 in one of the forests. In that case - IIRC - you need a replica of the free busy folder on Exchange 2010 otherwise the CAS can't look up the FB data of your 2003 mailboxes.

  • Hi Timo,

    Thanks for the update.

    I also believe the same but there is no clear information on this in the Technet. Curious to know if any one worked on the smilar setup ?

  • Hi Rich,

    You're correct. It could possible with installing Exchange 2010 SP1 server with the Client Access and Mailbox server in the Exchange 2003 organization and setup federated delegation that way.

  • Thanks Roderick,

    If i configure availability service between Exchange 2010 and Exchange 2007, how will exchange 2003 users from forest A will access free/busy information of users in exchange 2007 forest B. do we still will have to use interorg replication tool to maintain the replica of all the free/busy information of the exchange 2007 users in forest A for exchange 2003 users  ?
