Hi everybody.
A little question for a case I encounter.
I have a client (let's call it Company A) who's got an Exch2013 Server for emailing.
They just bought a company (let's call it Company B), whose emails are on Zimbra.
They want to migrate all Company B's mailboxes from Zimbra to Office 365, and keep all the Company A's mailboxes on their existing Exchange 2013 server.
What I Want :
- create the domain name of Company B in the existing AD of Company A
- create the Company B's user accounts with their domain name in Company A AD
- populate the mail attribute of the user accounts correctly.
What do I have to do in my DNS or on the Company A's Exchange server to prevent mail flow errors? Because I can imagine that if I just create the user accounts, the Company A's user will have issues while sending emails to Company B's users.
Thanks :)
