Specify Public Folder Referrals

In Exchange 2000, public folder affinities are transitive, meaning that if an affinity exists between site1 and site2 and between site2 and site3, an affinity automatically exists between site1 and site3. In Exchange 5.5 and earlier versions, public folder affinity is not transitive.

In a typical Exchange 2000 organization, all routing groups should be connected efficiently for mail-flow. Because public folder affinity is transitive, if you allow public folder referrals, then public folder referrals are available to all other servers in the connected routing groups. You can avoid this by restricting public folder referrals. By default, public folder referrals are allowed on connectors.

To specify public folder referrals:

1. Start System Manager
   On the Start menu, point to Programs, point to Microsoft Exchange, and then click System Manager.
2. Navigate to Connectors.
