I have an issue where my Exchange 2010 server won't synch with the domain, what i'm planning to do is to Configure new Exchange server in same exchange organization on different box (coexist), unmount the database from the current exchange and mount it back on the new Exchange server. Then, uninstall Exchange server decomission the DC, is it possible to do it in this way ? with the same window server and exchange version, and i will put the new exchange as a memeber server rather than a domain controller, in the new exchange i do install all the roles for exchange first ? and how do all outlook client autodiscover the new exchange server ? hope anyone can help with my concern, Thanks !
