I'm progressing through an Exchange 2010 to Exchange 2016 Migration with co-existence. I'm to the point where I need to Update Virtual Directory URL's and Domain DNS records and have stumbled upon a question I need answered before I'm comfortable proceeding.
Our users access OWA externally with, for example:
External - - https://email.domain.com/owa (Currently working External Access)
However, within the EMC and also through power shell commands I'm shown the current OWA external address and its different. For example I'm shown:
External - - https://webmail.domain.com/owa ("Configured" - non working External Access )
I am unable to find the currently working external address of https://email.domain.com/owa anywhere within my exchange or IIS environment. Where I do find it referenced is in my SSL Exchange certificate and in a MX record. What am I missing on the exchange side? How does Exchange now that https://email.domain.com/owa exisits and is a portal for access? Where is this configured such that I can't seem to reference it?
Assistance is appreciated.
