  • Dismounting Public Folders

    We've finally eliminated the need for Public Folders in our Company. Now, I want to dismount the Public Folders, do an offline backup of the file and delete it from the server. In my Exchange 5.5 days, this was a no-brainer. However, a trainer stated to my boss that this will cause Exchange 2003 to stop working. I can only assume that the trainer believed that the System Folders would also be dismounted. I do not believe this to be true, but I can not find proof. Here are my questions:

    If I dismount my only Public Folder tree on my mailbox Exchange 2003 server. What happens to the System Folders?

    Public Folders are in a *.EDB file, where are the System Folders stored?

    Thanks

    Re: Dismounting Public Folders

    You cannot eliminate public folders with Exchange 2003.
    You can reduce their use, but total elimination is impossible.
    Your trainer is correct. The system folders are held in the public folder store. Remove the public folder store and you will be unable to use Exchange.

    If you dismount the store, nothing happens to system folders and your event logs start filling up, Outlook 2003 stops working, no free/busy information, no Offline Address Book, cached mode will have many errors and the users will have a useless GAL.

    The first version of Exchange that supports public folders being removed is Exchange 2007, and you have to be exclusively Outlook 2007 (or higher).

      Hi Sembee,

      Thanks for your help.

      I've started archiving the old Public Folder data to PSTs and would like to do a "eseutil /d /ispub pub.edb" when I'm done. Since this will require a a dismount of the public folders I'll have to warn the users that Outlook will not be functional during the defrag. Given that bringing the public folders down will cause the below, but the eseutil /d /ispub is a supported Microsoft procedure (article 192185), can I assume that all is supposed to return to normal after a dismount, esutil /d and remount of the public folders?

      Thanks again

        I haven't done an offline defrag for over four years - it isn't something I do. I don't believe it is necessary and certainly should not be required as part of any kind of maintenance schedule.

          Only reason to make it part of maintenance is if your getting paid OT to come in and do it

          Rule of thumb to follow is that as long as online maintenance is completing, then your DB is in as good of shape as it can be.
