I added a second exchange to my network so that I could move all my mailboxes over and retire the exsisting server. The problem I am running across is that the install went along fine, I see my new exchange server in the ESM, I created a new user and linked him to the new exchange. When I configure that outlook for the new account, i enter in the exchange name and user name, hit check name and it gives me an "operation failed" error. i hit finish and it sets up the mailbox but then I am prompt for credentials to connect to my original exchange server. I keep getting prompted, i am able to send and receive between user accounts on the different exchanges, but i am repeatedly ask for my credentials for both exchange servers, i hit cancel and it goes away and shows my exchange connection offline. I am confused at this point, i've been looking on the web for answers, i have both my mx records set for priority 10, is this correct? did i miss a set somewhere? and help would be appreciated.
