We are currently running Exchange 2003 SP2/2007 SP1 mixed. When we originally installed Exchange in our org, we chose the option that we still had non-Outlook 2007 clients in our environment.
All clients are now OL 2007, and all mailboxes have been moved to Exchange 2007 servers, we only have a few test mailboxes left on Exchange 2003.
I understand that, whereas previously in Exchange 2003, Free/Busy information was held in Public Folders, in an OL/Exch 2007 combo, this information is now held in the actual mailboxes and accessed via the CAS.
Is there a command we need to run to make this happen, now that the last OL 2003 client has gone? Or is it automatic?
