Fix: Lync is Attempting to Connect to Autodiscover-s-Outlook.com

If you are using Microsoft Lync, you may receive a prompt about Lync attempting to connect to a certificate upon signing in.

Lync is attempting to connect to:

Autodiscover-s.outlook.com

CERTIFICATE DETAILS

Outlook.com

Issued by:

DigiCert Cloud Services CA-1

Owned By (Subject):

Outlook.com

The connection to the server is encrypted.

Lync cannot verify that the server is trusted for your sign-in address. Connect Anyway?

To resolve this certificate warning prompt, you can either check Always trust this server, do not show me this again or add outlook.com to your trusted domain list. Adding outlook.com to as a trusted domain in your domain will be the best option to ensure no other users receive this warning.
