Hi, I have 2 Exchange 2003 Sites 1 Exchange 2010 site and 2 Exchnage 2007 sites. My end goal is to get everyone consolidated into the Exchange 2010 site with remote move requests i am not there yet. the 2 Exchange 2003 and 1 Exchange 2010 are in 1 forest with multiple domains and the the other 2 Exchange 2007 sites are in separate forests each. How can i share the free busy information between all sites is using the Inter-Organization Replication tool my only choice? Is there away to share free busy from exchange 2007 and exchange 2010 and i can look at the 2003 separately? you have any suggestions? Thanks..

Hi JoesterS80, Do you still have Outlook 2003 users in the organization? If not, you can use GALSync. For more information, please see: Configure the Availability Service for Cross-Forest Topologies http://technet.microsoft.com/en-us/library/bb125182.aspxFrank Wang TechNet Community Support
