We are asked to separate a department of the company because it's going to be an independent unit (new company). This means seperate AD / networks, but common e-mail addresses. The company have a single domain today and don't want to change e-mail adresses.
Any suggestions how to achieve this?
I have thought of a possible solution with one front end Exchange to handle webmail, etc. And two other servers for mailbox storage, one for each network. And I intend to let the main company keep it's original AD domain (company.com), and establish a new iAD domain for the new company (e.g. company.net, separate forest). Is this a reasonable approach?
Suggestions / comments appreciated.
