SSL certificates are used to secure communication with any device outside of your Windows SBS 2011 Standard network. These methods include but are not limited to OWA, RWA, ActiveSync, and Outlook Anywhere. To access the network with any of these devices, you need to configure an SSL certificate. With Windows SBS 2011 Standard you have the choice of either a self-signed or trusted third-party certificate.
In order for clients to be able to establish a connection using the SSL certificate, the following conditions must be met:
The name of the certificate must match your public URL that the client uses to connect. For example,
remote.domainame.com
The certificate chain must be trusted by your client machine
The certificate needs to have valid date and time stamps
How to install, use, and transfer SSL certificates will be tested as part of this certification.
