SYMPTOMS
You have a Microsoft Exchange Server 2007 environment that has many public folder stores spread out across slow wide area network (WAN) links. In this situation, the public folder store on an Exchange 2007 server may take several minutes to mount.



CAUSE
This problem occurs because Exchange 2007 tries to contact every server that holds public folder stores when a public folder store is mounted. This behavior generates a remote procedure call (RPC) to the servers across the WAN links. The RPC can take several seconds for each server. Therefore, a long delay occurs before the public folder store mounts.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.



MORE INFORMATION
Currently, you cannot prevent this problem. Microsoft may reduce the number of available public folder stores or upgrade the WAN link to use more bandwidth in a future Exchange 2007 update.
