SYMPTOMS
You can programmatically create a second public folder store through Collaboration Data Objects for System Management and configure the folder tree item as a tree that is already being used by another public folder store on the server.

This scenario is unexpected; because to create a second public folder store on the same server that is associated with the same public folder tree is not permitted when you use Exchange System Manager.

This is not a supported configuration.



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server.



MORE INFORMATION
NOTE: Collaboration Data Objects for System Management is an application programming interface (API) that enables administrators to programmatically access management information on an Exchange 2000 server, which includes databases and mailboxes. The Emo.dll file provides these services.

Typically, a public folder tree on an Exchange 2000 server can be associated with only one Exchange 2000 public folder tree on a particular server. If an unassociated public folder tree does not exist, when you attempt to create a new public folder store by using Exchange System Manager you receive the following error message:

All the public folder trees already have an associated public folder store on this server. You will need to create a new public folder tree before creating this new public folder store.

After you use Exchange System Manager to create a new public folder tree on the server, when you try to create a new public folder store, the only available public folder tree that the Exchange System Manager displays for that server that is available to select is the new, unassociated public folder tree.

In addition, on an Exchange 2000 cluster server, you must insure that a public folder tree is unique to all of the cluster's virtual machines so that public folder stores on the server are not associated with the same public folder tree. Otherwise, in a failover scenario you may have multiple public folder stores that attempt to run on the same node that are associated with the same public folder tree.

Typically, you cannot assign the same public folder tree to two public folder stores on the same server. You can only create two public folder stores on the same server associated with the same public folder tree programmatically, as described in this article. However, do not even perform this procedure programmatically, as Microsoft does not support this configuration.
