I have a windows 2003 server with exchange 2003 I setup a new DC with 2008 server and exchange 2010 I migrated everything over to the new exchange 2010 box and everything seems well but if i shutdown the 2003 server then outlook says cant connect to server. I check the outlook settings and its pointing to the new server name. I dont know what i missed when i did the migration. Any suggestions?
Also when i run BPA i get this error only “Active Directory domain ‘DOMAIN’ has an unrecognized Exchange signature. Current DomainPrep version: 12639.”
