We had an issue where changes to public folder items on our Exchange 2010 server were being blocked from our Exchange 2003 server. This issue has been corrected but I need to get all the missed changes moved over now. If I do an Update Content on the Exchange 2010 side, it just does a backfill request for changes from the 2003 server and doesn't send anything. If I try and do a Resend Changes from the 2003 server, I get an error about the Information Store not being available (which I assume is the 2003 System Manager not being able to communicate with Exchange 2010). How do I get these changes moved from 2010 back to 2003?
