Problems with Public Folder Replication?
Having problems getting PF’s replicated (or moved) between 2003 and 2007?
KB 830181 suggests a fix for Exchange 5.5 / 2000 to 2003.
However, I have it on good advice (Thanks Mr Chandra) that this method can also fix any “sticking” folders in 2003 –> 2007. Only difference is that instead of restaring the MSExchangeTransport service, you have to bounce the box.
Mr Chandra also suggested you place this on the receiving server.
Worth a go for the sake of a reboot.
