We have a client who wants to add their new business domain (e.g abc.com) to their current business (e.g pop.com) in Exchange 2007.
They have just bought the new business and now they are trying to keep abc.com domain but move the domain to their Exchange server. The new business domain abc.com is currently hosted with another email hosting provider.
We want to move their all hosted mailboxes to their Exchange server. Could someone please provide me steps on how to do this?
