Sorry if this has been addressed already I could not find an answer that helped me.
So I have a Windows server 2003 with Exchange Server 2003 with functional web mail from internal and external.  (  I am trying to slowly move the server to a new exchange server that is on Windows Server 2012 64bit with Exchange Server 2010.  I have the new exchange server up and running and 2 users out of the 40 moved.  I could not move the other 38 because they use Exchange web mail and when I forwarded port 443 to the new servers IP I cannot connect into their mail.  (  The page does not resolve, if I log into the original ( I can get to everyone's email except the 2 users.  If I log into ( and use one of the tow users credentials I get redirected to a .local internal address. So my questions are as following:
1.  Is there a way to make both work?  If so what are the steps taken?
2.  Would it be better to just move everyone and the public folders and then try and figure it out?
3  Just walk away and pretend this never happened?  ( joking 3 is not an option)
