Install SSL Certificate Microsoft Outlook Web Access (OWA)

Step 1: Install SSL Certificate (and Intermediates if applicable)

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.

Install your SSL certificate for your version of IIS and your type of SSL certificate (EV or non-EV). A list of IIS servers can be found here.

Step 2: Configure Exchange Virtual Directory for SSL

  1. Expand the Exchange web site within IIS and select the Exchange sub directory, right-click and select Properties.
  2. Select the Directory Security tab. In the Secure Communications section, click Edit.
  3. In the Secure Communications dialog box, check the Require secure channel (SSL) checkbox. This will force clients to connect to the Exchange OWA via an https secure channel.

Verify Installation

 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. Use the https protocol directive. For example, if your SSL was issued to, enter into your browser.

Your browser's padlock icon  will be displayed in the locked position if your certificate is installed correctly and the server is properly configured for SSL.

For IIS SSL troubleshooting, Microsoft has designed a tool - SSL Diagnostics - to aid in quickly identifying configuration problems in the IIS metabase, certificates, or certificate stores.
