Hi All,

I have 3 servers ( Exchange1.mydomain.com, exchange2.mydomain.com and exchangedr.mydomain.com) with the same public SSL certificate

Mail.mydomain.com

Its stored in the Personnel cert store and has both Server Auth and Client Auth enabled, it was created using the exchange 2010 wizard and requested from a certificate authority.  

The fact that it has client auth enabled it has been causing problems with SCCM 2012 SP1 due to the fact that SCCM is using the mail.mydomain.com certificate for all three servers.  

My question is, if i untick the client Authentication option in MMC will this affect anything in our exchange setup? 

Server to server or client to server connectivity for example

Thanks David

Hello

Based on my experience, the client authentication don't affect your exchange setup.

Server authentication and client authentication are only the the intended purpose of the certificate.
