2007 and 2010 coexistence, OAB question.

    Question

  • Hi

    We are in progress of migrating from our old Exchange 2007 server to a new Exchange 2010 SP3 server.

    The new Ex2010 is now running and coexistence with the old 2007.
    All users are still running on the old 2007 server, and I have a few test accounts running on the new 2010.

    We have decided that we will not continue with Public Folders on the new 2010, so there will not be any replication.

    Right now the default OAB resides on the 2007 server, and is the generation server, distribution is set to Web-based and Public Folders.

    When I try to download the OAB with my test account in a Outlook 2013 client, I get the 0x8004010F, object cannot be found, error.

    How can I get the OAB working on both the new 2010 and old 2007 server. Should I create a new OAB on the new 2010 server?

    Remember that we do not want to create any Public folders on the new server.

  • Ok, so if I create a new OAB on the new 2010 server. Users located on the new 2010 server, will download the new OAB, and users who is still on the old 2007 will download the OAB on the exchange 2007 server?

    Is that correct?

    Actually, you can have all the users, both 2007 and 2010,  use the same OAB. Either the current one or a new one. Simply ensure the distribution point is to set to the CAS for both versions and the OAB is set as the default OAB on the properties of each database.

  • Hi,

    In addition to Andy, we can use the command below to set distribution points for CAS servers:

    Set-OABVirtualDirectory "OAB (Default Web Site)" -ExternalUrl https://contoso.com/OAB - InternalUrl https://contoso.com/OAB

  • Sure, you can create a new web-based OAB and make it the default for all the Databases or move the existing one to a 2010 server, uncheck the PF generation option and add the 2010 CAS as additional distribution points. Either will work. I like creating new OABs myself.
