We are in the process of migrating from exchange 2007 to exchange 2010. One of the steps we are doing with this is migrating the DNS name to the new 2010 server. We currently use www.name.com
for the 2007 server and are moving that to the 2010 server, while changing the 2007 to www2.name.com. After chaning this in DNS everything works except Free/Busy, When connected it now tells us that free/busy is unavailable for all the clients since they are still located on the server 2007 machine. How can we move the web name and still have free busy information populate properly?
