We are an organisation with a single Exchange 2010 server.
All our addresses are currently @aaa.co.uk.
We have now acquired another company (bbb.co.,uk) and would like some of our users to have the ability top receive email from both domains and to be able to send from either @aaa.co.uk or @bbb.co.uk.
It would be advantageous to have the emails kept separate which may suggest these users having a mailbox for each company.
We have all our mail coming in via an ISP, who host our MX records, so I assume we just get them to host the MX records for bbb.co.uk also.
We do not have an Edge Transport server role.
Where do I go from there?
Am I right in thinking we need to create an Accepted Domain for bbb.co.uk then create separate mailboxes?
Well explained guidance would be much appreciated.
Regards,
