Public folder tree database assignment
[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine the value of the msExchOwningPFTreeBL attribute for each msExchPFTree object class. The msExchOwningPFTreeBL attribute stores a list of distinguished names of public folder stores that contain a replica of the public folder tree. If the Exchange Server Analyzer finds that the msExchOwningPFTreeBL attribute on a public folder tree object is empty, a warning is displayed. This warning indicates that a public folder tree is not owned by any public folder store.
Each public folder tree (also called "public folder hierarchy") is linked back to a public folder store. You must create the tree first and then the store. If you have not yet linked the tree to a database, this warning is displayed. Each public folder tree can have only one store on a particular server. A tree can have multiple stores when each store exists on a separate server. In such a configuration, Exchange replicates information among the stores to keep the hierarchy consistent.
If Microsoft Office Outlook® Web Access clients try to connect to any public folder within a tree that has no associated public folder stores, a "service unavailable" (HTTP 503) error occurs.
To correct this warning, you must do one of the following:
Link the public folder tree with a public folder database. To link the public folder tree with a public folder database, you must first create a new public folder database, and then locate the public folder tree and link them.
Delete the public folder tree. If you have not yet linked the public folder tree to a public folder database, no user data will be lost when you delete the tree.
To link the public folder tree with a public folder database
In Exchange System Manager, expand the server to which you want to add a public folder store.
Right-click a specific storage group, point to New, and then click Public Store.
In Name, type a name for the new database.
To associate the public folder tree with the database, click Browse, and then select the public folder tree that is displayed in the Exchange Server Analyzer warning.
To save your settings, click OK.
To mount the new store, click Yes.
To delete the public folder tree
In Exchange System Manager, expand the Folders node where the public folder tree exists.
Right-click the public folder tree that you want to delete, click Delete, and then click Yes.
