So let's say I have either an Organization with all Exchange 2003 or all Exchange 2007, or even a mix. When I introduce a new (second, third, whatever...) public folder database onto a new Exchange server, it is my understand that the public folder hierarchy gets sent to all other public folder databases within that routing group.My questions are as follows:1. Referrals work automatically within a routing group. Correct?2. For referals across routing groups, I will need to enable public folder referrals on the Routing Group Connector or SMTP Connector. Correct?3. Do the System Folders get replicated to all other public folder databases within your routing group automatically? If not, then I assume that if I want to have replicated copies of things like the OAB and Free/Busy across my multi-site org, I will need to ensure that replicas are added for all public folder servers within that routing group and enable referrals across my Routing Group Connectors or SMTP Connectors?Thanks.

Hi, 1. Referrals work automatically within a routing group. Correct? Correct.2.

Public folders doesn't get replicated to a new server automatically. You must create replicas of the desired folders on the new server. Leif
