Updating exchange certificate

Install your SSL certificate for your version of IIS and your type of SSL certificate (EV or non-EV). To verify if your certificate is installed correctly, use our Certificate Installation Checker.

Test your SSL certificate by using a browser to connect to your server. For example, if your SSL was issued to secure.mysite.com, enter into your browser.

You can use a single Web site certificate and bind that certificate to each of these Exchange Services, or you can request a separate certificate for each service.

You can obtain a Web site certificate from a standalone Microsoft Certificate Server, an enterprise Microsoft Certificate Server, or a commercial certificate authority.

Outlook Web Access (OWA) traffic is handled by Microsoft's Internet Information Services (IIS) web server.

Therefore your SSL certificate must be installed on IIS.

Before it can successfully negotiate a secure SSL/TLS link with the Exchange Server, the email client must trust the certificate authority (CA) issuing the Web site certificate to the Exchange Servers services.

The email client does not need a machine certificate to accomplish this; the email client only needs the root CA certificate in its Trusted Root Certification Authorities machine certificate store.You can perform the same steps on a Windows 2000, Windows XP or Windows Server 2003 machine to confirm that the root CA certificate is in the Trusted Root Certification Authorities machine certificate store.There are several methods you can use to import the root CA certificate into the email client computers machine certificate store if you host your own Microsoft standalone CA or Microsoft enterprise CA.Therefore, you must update the Internal URLs, External URLs, and Autodiscover Service Internal URI to match the certificate FQDN. This issue is that when you are trying to make a connection to Autodiscover via https://autodiscover.domain.com, the Outlook client does not successfully make a connection to it and you get a certificate error.The certificate you see pop up in Outlook during the error isn’t even the certificate that is located on Exchange.To copy something (like a thumbprint), right-click the shell window and Click Mark.
