Are 2003 and 2010 in the same AD forest? Does the 2010 server have a public folder database? Does your RGC allow for public folder referrals? Are you using Outlook 2007 and 201o clients or are there older client versions being used? Remember, Exchange 2003 doesn't know about getting F/B info directly from a mailbox (IOW, 2003 has no CAS, just F-E serevers). So you're going to have to have public folders on the 2010 server so clients have the F/B data available. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
