You receive an error message when you try to synchronize your offline folder file if the Organizational Forms Library on your Exchange computer has been re-created or cannot be located

When you try to synchronize all folders from a client with an offline folder (.ost) file, you receive the following error message: If you review the synchronization log, you see the following entries:

The following MAPI code may be displayed in the synchronization log for the same issue:

This issue may occur in any one of the following scenarios:

• The Organizational Forms Library has been deleted and re-created after the .ost file has synchronized the library. The internal object ID of the new Organizational Forms Library is different from the internal object ID of the original Organizational Forms Library. Therefore, the offline folder store encounters problems trying to synchronize because the offline folder store has the ID of the original Organizational Forms Library.
• The replica of the original Organizational Forms Library has been removed from the public folder on the Exchange computer that you try to synchronize with.
• The Eforms Registry system folder does not exist. For example, the Eforms Registry folder may not exist if you removed the first Exchange computer in a site without following the correct procedure.

The Organizational Forms Library has been deleted and re-created after the .ost file has synchronized the library

To resolve this issue, verify the following:

• If the default permission on the Organizational Forms Library is set to None, the client will not synchronize. However, with these permissions, the synchronization log will contain the following:

        Error synchronizing folder
        [80004005-501-0-540]
        The client operation failed
        Microsoft Exchange Information Store
  						

  You must set the default permission for the Organizational Forms Library to Reviewer to prevent this error.
• On all servers in the site that have mailboxes, verify that the Exchange Services were stopped and restarted after the new Organizational Forms Library became a replica in the site.
• On the client side, the Organizational Forms Library will synch correctly on the second logon and synchronization of all folders.

The replica of the original Organizational Forms Library has been removed from the public folder

This issue can also occur in a situation where the replica of the original Organizational Forms Library has been removed from the public folder. As long as the original Organizational Forms Library has not been deleted, a replica can again be created in the site and the error message will disappear after the folder has been successfully replicated. To create a replica, follow these steps:

Microsoft Exchange Server 5.5

1. Start Microsoft Exchange Administrator, and then connect to the server that holds the original Organizational Forms Library.
2. Expand Folders, expand System Folders, and then expand EFORMS REGISTRY.
3. Click your Organizational Forms Library folder. For example, click Organizational Forms.
4. On the File menu, click Properties.
5. Click the Replicas tab.
6. In the left column, click the server that you want to replicate the folder to, and then click Add.
7. Click Apply, and then click OK.

Microsoft Exchange 2000 Server and Microsoft Exchange Server 2003

1. Start Exchange System Manager.
2. If administrative groups are displayed, expand Administrative Groups, and then expand the group that you want to work with.
3. Expand Folders.
4. Right-click Public Folders, and then click View System Folders.
5. Expand EFORMS REGISTRY.
6. Right-click your Organizational Forms Library folder, and then click Properties.
7. Click the Replication tab.
8. Click Add, click the server that you want to replicate the folder to, and then click OK two times.

Eforms Registry folder does not exist

If the Eforms Registry folder does not exist, you can use the Guidgen.exe tool to create a new system folder to replace the Eforms Registry. You can use the Guidgen.exe tool on a server that is running Exchange 2000 or Exchange 2003.

Note You cannot reset the GUID for only a single site folder. If you reset the GUID, all offline address books and Free/Busy Information for a single administrative group are deleted.
