Hi I have just added a new 2010 Exchange server to an Exchange 2003 Org and am using it exclusivly as a public folder server. Currently public folders in exchange 2003 are viewed as messages rather that the default notes after a registry change KB 817809. How do I make sure that the default message class is set to IPM.Note and not IPM.Post in exchange 2010 thanks ian

Shouldn't need to do anything. It should be the note message format by default. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources
