We recently migrated our Exchange 2003 environment to Exchange 2007. Everything went very smooth and we decommissioned the old 2003 server. Well, a user brought to my attention last week that when she was scheduling appointments in her Calander in Outlook 2003, the Free/Busy data wasn't pulling up. I did some research and it looks like it's because we didn't replicate the Schedule+ Free/Busy data from 2003 over to 2007's public folder. Some solutions I saw on the net was to replicate, can't do that because the server is gone. The other options included upgrading to Outlook 2007 (can't afford it right now) or use OWA. Well OWA works, but that can't be a solution for 100+ users right now. Does anyone know how to get this working on Exchange 2007? How would this work if you started a new company with 2007 and used Outlook 2003 without ever having Exchange 2003?
