We are migrating from Exchange 2003 to 2010, then possibly on to 2013. For now I have a Exchange 2010 with all the roles on one server running on Server 2012 Hyper-V and have moved a couple test users over. Email comes and goes to them without issue.
However, I am not sure how to set up OWA for both systems. We have been using OWA for Exchange 2003 but something I did setting up 2010 seems to have redirected that. Anytime I go to the external URL we used to get to OWA on Exchange 2003 it rolls that test user over to the URL for the 2010 server, even tho Outlook Anywhere is not enabled yet on it.
What did I screw up and can I have both running at the same time?
