Install an SSL Certificate on Office 365
After the CA delivers the SSL certificate to your email, download the ZIP folder and extract its contents. Make sure your SSL Certificate has the .p7b extension. If it doesn’t use an SSL converter tool, copy the contents of your SSL certificate file into a new plain text document and save it as a .p7b file.
To complete the Microsoft Office SSL installation, perform the following:
- Go to Start > Administrative Tools > Internet Information Services (IIS) Manager.
- From the main section, select Server Certificates
- Under Actions, click on Complete Certificate Request
- In the Complete Certificate Request window, click the three-dotted button, and select the location of your SSL Certificate file
- Create a friendly name for your SSL certificate
- From the Select a Certificate Store drop-down list, select Personal then click OK.
Note: If you receive an error message, during the installation process click OK then Cancel out the Complete Certificate Request wizard. Refresh your IIS console (click F5 on your keyboard) and look for your new certificate in the middle section under Server Certificates. If you see the new certificate, your SSL installation was successful. You will have to generate a new CSR code and reissue your cert if it’s not there.
- Next, you must assign and bind the SSL certificate to your site. Select your server, expand the Sites folder, and click on the website you want to secure
- Under Actions, click Bindings
- In the Site Bindings Window, if there isn’t an existing HTTPS binding, click on Add and change Type from HTTP to HTTPS
- From the SSL Certificate drop-down list, select the friendly name of the SSL certificate you want to use, then click OK.
Congratulations, you’ve successfully installed an SSL certificate in Office 365.

1. Does Office 365 require an SSL certificate?
Office 365 requires a third-party SSL certificate to encrypt communications between your clients and the Office 365 environment. You must install the SSL certificate on your server.
2. Does Office 365 use SSL or TLS?
Office 365 uses the TLS (Transport Layer Security) protocol to encrypt communications between clients and servers. SSL (Secure Sockets Layer) is deprecated and no longer in use.
3. How do I find my Office 365 certificate?
The SSL certificate is installed on your externally facing web (in our case IIS) server and authenticates with Office 365. To find the IIS certificate: Navigate to Windows Start > Windows Administrative Tools > Internet Information Services (IIS) Manager. Click on the server name in the Connections left-side panel. Double-click on Server Certificates to display certificates in the IIS Manager. Select the certificate you need.
