Last Modified: 2012-08-13
I have a exchange 2003 and we just installed an exchange 2010. all mailbox and everything else except public folders are now on the new exchange 2010 server. I have moved replicas of the public folders but still all clients are point to the exchange 2003 server for public folders. At this time we dont use public folders so how can i the outlook client to look at the 2010 for public folders and then remove the old exchange server.

You need to remove the public folder database from the exchange 2003 server

 On the Exchange 2010 server you need to set the default public folder database for the mailbox database that contains your mailboxes.
