Exchange 2013/2010 - Co-Existence, URLs.

Hey Team,

I am sure this is well documented and i for some reason cant seem to get good solid answer. But here is my questions. what are the correct URL settings for (OWA, ActiveSync, EWS) etc for Exchange 2013/2010 in a coexistence scenario?

1) All servers in the same ad site

2) mail. autodiscover, pointed to the 2013 server

3) 2013 server is internet connected.

Am i supposed to clear all the 2010 URLs?, Just the external ones? Use a separate namespace?

Thanks,

Robert
