  • Cannot mail enable Public Folder


    I have Exchange 2000 SP3 running in mixed mode. I cannot mail enable any new Public Folders. The existing Public Folders work that were mail enabled before. The error I am getting is:

    Event Type: Warning
    Event Source: MSExchangeIS
    Event Category: General
    Event ID: 9543
    Date: 9/15/2005
    Time: 12:40:28 PM
    User: N/A
    Computer: Server01
    Unable to create Public Folder proxy object for folder "Folder1" in the Active Directory.

    The new Public Folder doesn't show up in the Microsoft Exchange System Objects Container. I can right click the public folder and mail enable it but this does nothing. I rebuilt the Recipient Update Services. The Recipient Update Services is working as I can create a new user and it stamps the email address. Any help is greatly appreciated.

    The 9543 Event ID alone is not quite enough to figure out what is happening
    here for sure. But from what research I was able to do I can recommend the
    following actions.


    1. Open Active Directory Users and Computers
    2. Turn on advanced features under View.
    3. Navigate to the Microsoft Exchange System Objects node. You should see your public folders in this location
    4. Set the public folder to "Allow inheritable permissions from parent." In our case the Administrator was the only person listed and there should be numerous other users with permission to the PF.
    5. Now go into System Manager and look at the properties. You shouldn't get the error message.

    If no result:

    1. Change over to Exchange Native mode if you are not there already
    2. Run exchange domainprep again this should reset the exchange groups
    3. Run exchange setup again and do a reinstall (if prompted do not over
    write any files) this should redo any missing or not quite correct
    4. Restart the Exchange server and all Domain controllers

    If after do that you are still unable to get this functionality to work then
    I would recommend contacting Microsoft and opening a support incident as it
    will require more indepth troubleshooting in order to determine what is
    causing this issue.

    Good luck
