The SMTP IgnorePFTimeLimit registry value has been manually set
Topic Last Modified: 2007-01-17
The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine if the number of days that the SMTP service routing engine bypasses the new public folder store has been manually set:
If the Exchange Server Analyzer finds IgnorePFTimeLimit to be present and configured, a non-default configuration message is displayed.
When a new public folder store is brought online, you may notice in the Queue Viewer that the local delivery queue is growing. If the public folder hierarchy is large, the messages in the local queue continue to grow and may take additional time to be delivered. In some cases, the messages may not be delivered.
When the new server is introduced, its distinguished name is added to the msExchOwningPFTreeBL attribute of the administrative group's Folder Hierarchies Public Folder object in the Active Directory® directory service. When the categorizer for the server that receives messages bound for public folders reads the msExchOwningPFTreeBL attribute, it should first select the local public folder store, if it exists. For load balancing, it then selects the public folder stores in the order that they are listed. Because the new server is listed first, the messages are routed to it, where they are added to the new server's local delivery queue. If a public folder store has not received a copy of the hierarchy, the server cannot route the messages to a store that owns a copy of the destination folder.
You can avoid this issue by adding the IgnorePFTimeLimit value to the registry of the new public folder server. This will specify the number of days that the routing engine bypasses the new public folder store.
