Hi,
I am tasked with deploying Exchange 2010 SP1 on the premises in order to move our mail services on site. I've followed the instructions of deployment assistant, which enabled me to successfully deploy the server and its services.
My issue now though is that, because the on premises and the hosted service utilizes the same Login IDs, Outlook will constantly prompt my users for the local password, though their intention is to sign into the hosted service mailbox as we have not yet cut over.
I've tried setting the MX record priority on the local DNS server, however this only ensures that outbound mails are routed using the hosted service but does not prevent Outlook from trying to connect to the local mail server with the same UPN.
I need to be able to test the deployment with the our domain name (ex. john.doe@acme.com) without interfering with the production environment even if they use the same Login ID.
I know I can set up an alternate domain suffix (actually I've already done this) and test everything, however my manager is pretty peculiar and likes to test things apples-2-apples.
Any advise you can provide would be fine.
Quen
