legacy namespace configuration Exchange 2013 - 2007

Hi,

I am going to be setting up a migration in my lab from Exchange 2007 - Exchange 2013 and I have a question about legacy namespaces for OWA/Active Sync access.

I understand how to create the legacy namespace in DNS etc and that the legacy names needs to be on the certificate etc, but what I'm not sure about is what to change on Exchange 2013 and 2007 to make the redirection happen when a 2007 mailbox user hits the 2013 cas server.

Also what is the end user experience for OWA/ActiveSync?

There is nothing that you need to do on Exchange 2013.
As long as you configure the correct URLs on the Exchange 2007 server, then Exchange will handle it for you.

For OWA, they will get the login screen from Exchange 2013 and as long as you have the correct URLs and authentication settings, they just get redirected to the legacy URL.

ActiveSync will proxy, so that shouldn't cause any problems for the end users.

Thank you Simon - Most helpful as always.

I followed Microsoft 2013 deployment assistant and have completed this in my lab over the last couple of days. Pleased to report that legacy redirection worked like you said.
Mailbox migration was a breeze too - After a restart clients were back working in seconds.

Just need to work on removing the legacy server now

Cheers
