I am examining our default domain policy and I noticed that there is a System Services setting for MSExchangeSA. Is this something that Exchange 2010 automatically installed in the policy when we built our Exchange 2010 system? I don't remember specifically adding it there and I'm not finding much on the Internet about it, so I'm wondering why it's there. I've read that the default domain policy should be limited to password policies, lockout policies, Kerberos, and network security type settings.
If you have Exchange 2010, do you have a MSExchangeSA in System Services in your default domain policy?
Thanks.
