Cross forest migration Exchange 2010 SP2 to Exchange 2010 SP2 RRS feed

  • Question

  • Hi,

    We are planning cross forest migration Exchange 2010 SP2 to Exchange 2010 SP2.

    Requesting you to please help us out for below scenario.

    Source Exchange 2010 SP2:- abc.com
    2AD, 2CAS & 2 MBX servers
    Database:- 4
    Total Users :- 3500
    Accepted Domains :- 8
    Total Data:- 5TB +

    Target Exchange 2010 SP2:- xyz.com
    Resource allocated same as above.
    Now we have to migrate users along with data to target forest xyz.com keeping both setup live, as moving 5TB + data will be a ongoing process and the same will take some time.

    With the guidelines mentioned in http://careexchange.in/cross-forest-migration-guide-exchange-2010-to-exchange-2010/#comment-14203 we are able to migrate test users along with data, but after migration the migrated user is not able to connect through MS Outlook even not able to login into OWA. It gives error “The Outlook Web App address https://mail.abc.com/owa is out of date.”

    Kindly let us know how to solve this issue.

    Kindly let me know if you want any more information from our end.

    Thanks in advance.


    Thanks and Regards, Shashank Kudi

  • Hi Shashank,
    Do you have certificates properly installed and configured in the target Exchange?
    If not, Please configure certificate and import the certificate to the trusted root CA if you are using internal CA cert.

    Thanks, MAS

  • Hi,

    Thanks for your quick revert. We have rechecked and confirmed the certificate configuration. The same is OK.
