Hi Fellow Experts.

I am in the design phase of an Exchange 2010 setup and wanted to know your thoughts on this.

Company a with domain @abc.com
Company b with domain @def.com
Company A acquires company B.

We are trying to find out how to incorporate Company B's email domain into the Exchange 2010

Criteria:
a) Emails sent by users of CompanyB, should show the from: address as user@def.com
b) No GAL Segregation required.

Options:
1) New Accepted Domain for CompanyB and Configure address-rewrite and change the domain to @def.com

2) New Accepted Domain for CompanyB and use IvaSoft Sender Based Routing.

3) Install Exchange 2010 in multi-tenant mode.

CompanyA, is still running Exchange 2003 and will be migrating to Exchange 2010, so hosted-exchange mode is also an option.

Please bear in mind that CompanyA, might be acquiring more companies down the line, so the solution has to be scalable.

Thanks for your inputs.

Hey there

You simply need to add def.com as accepted domain and configure and email address policy for users with, say, "company = def" to have their primary smtp address as user@def.com you don't need address rewriting at all

Or I totally missunderstood the question

You are right.
I ended up doing some more customization, but I dont need any of the other stuff. Accepted domain, EAP, configure OU's etc appropriately - and you are good to go.
