ESM Gives Error Id No: c1038a21 when click on Folder Properties of General Object under Public Folder Store

Posted on 2006-05-05

Background: I was running Exchange 2000 and wanted to retire it.  I loaded a new server with W2K3 Server and Exchange 2003 Server, changed what I *thought* I had to in the ESM to point to new server.  I uninstalled Exchange 2000 off of old server and turned it off.  Mail tosses but when a client tried to access the Offline Address Book it would error out.  I created a second "Offline Address List", Set as New Default and then that error went away.

However, I still can't access my Public Folders (the folders and hierachy show but errors when I click on any folders).  Also, from the ESM, if I try and click on:

Public Folder Stores\Public Folder Instances\Default
Public Folder Stores\Public Folder Instances\exchangeV1
Public Folder Stores\Public Folder Instances\globalevents

I get this error:  The Mail Proxy for this server can not be found.  This may be due to replication delays.  The mail enabled pages will not be shown.  ID no: c1038a21.

Any ideas?

    Did you check these links -->

    You may receive a c1038a21 error message when you try to use Exchange System Manager to look at the properties of a public folder

    When you copy a public folder from Microsoft Outlook by using an Outlook client computer, the copy of the public folder may contain a reference to the original folder's Active Directory entry in Exchange 2000

    Whenever you mail-enable a public folder, a directory object is created in "Microsoft Exchange system Objects" container in Active Directory. You can view this container by enabling "Advanced features" in Active Directory Users & Computers.
    If you are not able to mail-enable a Public Folder. Check this container. It should be there at the root under your domain and check the permissions on the container too.

    Are you able to access Public folders when you view them via the public folder tree in ESM

    Expand Folders
    Expand Public folder tree
    Over here you have your public folders
    If you right click on public folders you get the option to view your system folders

    Check the settings of the OAB server, RUS server in ESM. are they pointing to the new server or the old server?
    Also check whether the routing master is set to your new server and not the old one

    Did you replicate the public folders to the new server before removing the old exchange server?

    Are you getting this error when you check the properties of all the folders or just the ones mentioned above?

    The first link you provided I saw while trying to find the solution.  Unfortunately I can't find the setting they're asking about (the PR_PF_PROXY).  The Information Store Viewer isn't the most friendly application.  I'll keep trying though and let you know.


    Before I uninstalled Exchange 2000 off of my old server, I updated the OAB and RUS to the new server name (it wouldn't let me uninstall until I did).  HOWEVER, I did NOT replicate the public folders to the new server (doh!).  That's GOT to be my problem.  An I'm only getting the error on the folders mentioned above (no error on the others).


    I exported my Public Folders to a .pst before I did all this.  At this point I'm ready to just delete the old Public Folders and simply re-create them with the .pst.

    Thanks for the help, but I ended up finding my own solution.  First, I deleted the Public Folders and re-creating them.  That did NOT solve the problem.  

    Here is what DID work:

    1) I stopped exchange
    2) deleted the public folders (pub1.edb and pub1.stm)
    3) restarted exchange
    4) attempted to mount it (where it gave me an error and asked if I wanted to re-create them) everything then worked just fine
    5) re-imported all my folders from a backup.

    It had something to do with the GUID of that particular Private Store being lost or something.
    A good article on how to fix this is here:,289483,sid43_gci1057114,00.html?bucket=ETA (the difference between this article and Exchange 2003 is that you don't have to go change any GUIDs, I skipped that entire step and everything worked just fine.)
