I currently host my own exchange 2010 server in a private cloud. It hosts a growing number of customer mailboxes. I am looking for a way to enable single sign on for my customers (who have their own AD domains) to access their mailboxes.
Would this be possible by moving my AD to Azure and then federating my customers AD domains with my azure domain?
The objective is single sign on to my exchange environment for my customers who have no on prem exchange.
