Our company running one exchange server 2010 and we would like purchase SSL certificated for our exchange server. Our exchange server is setup on different domain controller which is warriortech.com and our internal domain controller name is warriorstech.com.sg
Internal Domain Controller name: warrirsttech.com.sg
Exchange Server Domain Controller Name: warrirsttech.com

Above is the domain name and I would like to seek for advice below:
1. What SSL certificated domain name should I purchase to install in exchange server
2. After install SSL certificated any impact on end user and what end user need to do?
3. How to setup Autodiscovery and which domain controller i need to set ?
By valid I mean, anyone can resolve your domain or hostname using a public DNS lookup.
https://LetsEncrypt.org provides free SSL certs.
