Federated Free / Busy unavailable for Exchange 2003 mailbox users. RRS feed

  • Question

  • Hi Everyone

    I've just completed the setup of an organisation share to share free / busy information with a partner, and can't seem to get the free busy info to appear for the Exchange 2003 mailboxes.

    Our organisation is still at Exchange 2003 so we installed exchange 2010 to be able to setup a Microsoft federation gateway trust with our partner company that is on Exchange 2013.

    mailboxes:

    prescoe = exchange 2003

    Test10 = Exchange 2010

    Two test  = Exchange 2013

    As the image shows when logged on from a mailbox on Exchange 2010, we can see the free-busy information for both mailboxes, the Exchange 2003 + Exchange 2013.

    However when I open the prescoe mailbox, which resides on Exchange 2003, I can not see the free / busy of the federated Exchange 2013 account called two test.

    Clearly everything is fonctional from a federated trust point of view, so what's missing to allow Exchange 2003 mailbox the ability to see Exchange 2013 free- busy info.

    Any help is appreciated.

    Regards
