Hi guys,
Domain A is a SME with Exchange 2007, recently installed 2010 and working in a mixed mode. All working well.
A company took over my company which looks after Domain A. A domain migration was done into Domain B, however the mail environment was left "as is" for now in the original domain.
So all objects are in a single domain (parent company), but we have the old domain A with the users mailboxes still.
Domain B is now about to deploy a 2010 infrastructure. Currently I use an SRV record on the split-brain internal DNS to sort out Autodiscover. I assume that when Domain B publishes their SCP into the domain that all the users sit on, my users (that have their mail on Domain A still) will pickup the SCP and get errors....
So having everyone in domainb.com at the moment, but with a set of users having their mailboxes on domaina.org. Their SMTP is still domaina.org too. When domainb.com roles our their Ex2010 CAS and publishes an SCP how can I prevent my users from getting tripped up.
How would / do you implement Autodiscover so different mail users in a single domain get put to their local CAS if using local domain email but gets pushed to a trusted domain if using a different email domain....?
Ideas welcome! :)
Thanks - Steve
