Actually "sharing" a calender between two different Exchange Organization RRS feed

  • Question

  • Hi guys,

    i'm currently working on a project where we're deciding wheather to connect a new Exchange 2010 Organization to an Exchange 2003 organization. 
    I read a lot of stuff about the Exchange Interorg replication tool that enables a free/busy replication based on Public Folders and the availability service between an Exchange 2003 and Exchange 2007 organization.

    We were thinking about using a 'legacy' Exchange 2007 server in our newly Exchange 2010 and connect it to the Exchange 2003 organization using the Interorg tool.
    This way we'll have the free/busy info from both environments available to the users in both Exchange Organizations.

    Can one of you guys tell what the granualarity of this information is? I know a user can see the free/busy information of a user in another forest while creating a new appointment, but is it possible to actually open cross-forest shared calender? (Outlook, Open -> Shared Calender -> user from the other Exchange Org.)

    Regards,

    Ruben

  • Although you can synchronize free/busy information across forests and use it to schedule meetings, you cannot use the Open Other User's Folder feature in Microsoft Office Outlook to view the calendar details for a user in another forest

    ----------Synchronizing Multiple Exchange 2003 Forests

    For opening the calendar in another forest, the following is the options I know:

    ·         Exchange 2010’s new feature, Federation can easily share the calendar cross the forests

    ·         You can use the linked mailbox to open the calendar in another forest

    ·         If you are using outlook 2007, the calendar can be published to internet, and then share to person in another company, but with read-only permission
