Dear All
I implement exchange 2013, but our client is not join to domain, we have a problem about certificate warning when try to access owa, both internal network and external network so my manager decision to buy external certificate, my question is
1. I have 2 cas server with NLB, so it need to install external CA on these CAS only or install to all Exchange server
2. What type of certificate that I should buy ( I used webmail.domain.com/owa )
3. I have other web server used on same these domain, it will have effect or not
Thank you
