Consider the following scenario:
- You deploy some public folder databases in a Microsoft Exchange Server 2010 environment, and the environment contains multiple Active Directory sites.
- A user’s mailbox is located on a Mailbox server that has no public folder databases.
- The user tries to retrieve the public folder hierarchy or the public folder content.
- The default public folder server is unavailable.
This issue occurs because the Exchange server randomly selects a public folder server from the same administrative group regardless of the connection cost or the network access speed.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
