Hi, Please try to run ExBPA to have a health scan and then post the error information here. Besides, I'd like to know how many Exchange Servers in the network. Did Exchange 2007 pure install or just upgrade from legacy Exchange environment? Please try to use Get-public folder \non_ipm_subtree |fl and then post the result here. We may need to delete those duplicated system folder.

Thank the Exchange 2007 Upgrade From exchange 2003 Now the envirnment is 2 x Edge server and 2 xCAS/HUB/MBX server in 2 sites. I heard from old guy, the error msg happen in Exchange 2003 before. But we only have 1 public Folder, I am thinking do i need replication? and Why I need it?

Yea...you will need to replicate the PF to the exchange 2007 server.
