Public folders not visible between outlook clients with Exchange 2013

    Question

  • At this moment we have Exchange 2013 deployed (2 server all roles combined).
    The majority of Outlook clients are outlook 2007 with the supported fixes.
    We created also new modern public folders.
    When I create a public folder in Outlook 2007 an other Outlook 2007 client see the folder directly.  Also the Outlook 2013 see the public folder directly.
    When I create a public folder in Outlook 2013 it takes long time before Outlook 2007 clients see this.
    If the folder is not available and I create the folder with the same name as in Outlook 2013 then Outlook 2007 doesn't allow it because it exist. But I don't see it at that time.
    Restarting outlook 2007 has no effect.
    Any suggestion where to look?

  • Hi,

    Are the Outlook 2013 users are on the same server as the Outlook 2007 users?

    Please firstly make sure the replications are working properly between the two public folder databases.

    Thanks,

  • Simon,
    I don't have public folder databases anymore in Exchange 2013!!.

    And Yes I made sure that the test users have set the DefaultPublicFolderMailbox parameter to the same ROOTpublic folder mailbox.

  • Hi,

    OK. Then the issue can be causes by two possible causes:

    1. The Outlook client which creates the public folders has some caches when syncing to the mailbox. To narrow down this cause, I suggest we switch the Outlook client to online mode then see whether we can reproduce this issue.

    2. The cause can also be related to the public folder hierarchy sync issues between the public folder mailboxes. PF hierarchy is updated on all PF mailboxes where users are connected after 15 minutes. We can manually sync the hierarchy by running:

    Update-PublicFolderMailbox

    Let’s check the result again.

    Thanks,

  • Hi,
    Update-publicfolder mailbox not needed. (hierarchy is up to date because the other client is not allowed to create PF with the same name).
    To avoid this I pinpointed the (test)users to use the RootPublic folder[DefaultPublicFolderMailbox setting]  (which hold the writable copy of PF hierarchy).  
    It makes no difference if the outlook client is in cache of online mode.

    Regards
