Greetings

Currently i am using Exchange 2007 setup (xyz.com) and it is not published to the internet i.e. only the Domain joined users have access to it and mx records are not hosted for xyz.com

And have hosted solution (abc.com)

Now, I am planning to upgrade the Exchange 2007 to Exchange 2013 infra. But here my requirement is to use abc.com as the email address domain.

My plan is to migrate and add abc.com in accepted domain. Please suggest if this can be achieved by doing so and if yes, what other changes i need to plan as i want to have the same email address domain (abc.com) having the virtual directories by the same name (mail.abc.com)

Please provide yours inputs.

Thanks

That abc.com is for mail only, ie you don't access that mail through "mail.abc.com" on that address?

You can use internal relay domains to accept abc.com mail in your organization and mail drop unresolvable recipients in that hosted solution (shared namespace). A connector for that namespace will determine where those message will be dropped (hosted solution). Alternative is to use the hosted solution as primary maildrop, but that requires that you can configure 'internal relay' and transport in your tenant.

Hi,

Thank you for your question.

By my understanding, you want to use Exchange 2013 with domain abc.com to replace domain xyz, right? If I misunderstand, please be free to let me know.

If that, we could refer to the following links to migrate Exchange 2007 to Exchange 2013 by crossing domains:

But we suggest you install Exchange 2010 in abc.com domain, then we perform cross domain migration from Exchange 2007 to Exchange 2010, then migrate to Exchange 2013.

If there are any questions regarding this issue, please be free to let me know.
