Before you can request a certificate through our portal, you need to use the Exchange Admin Center to generate a Certificate Signing Request (CSR) for your website.
If you need to secure more than one domain name, we recommend that you use a Multiple Domain Unified Communications Certificate (UCC) with your Microsoft® Exchange Server. For more information, see What is a Multiple Domain (UCC) SSL certificate?
- Log in to the Exchange Admin Center.
- From the left menu, select Servers, and then click Certificates.
- Click + to start the Exchange Certificate wizard.
- Select Create a request for a certificate from a certification authority, and then click Next.
- Enter a friendly name to identify this certificate, and then click Next.
- If your CSR is for a wildcard certificate, select Request a wildcard certificate, enter the root domain name, and then click Next. Otherwise, click Next without selecting or entering anything.
- For Store certificate request on this server, click Browse, select a server to store the pending certificate request, click OK, and then click Next.
- Select and/or add the domain names (also know as Subject Alternative Names or SANs) that you will use to reference or connect to your Exchange server, and then click Next.
- Add your organization’s information, and then click Next:
- Organization name — Enter the full legal name of your company or organization.
- Department name — Enter the organization within the company (such as IT Department) responsible for the certificate.
- Country/Region name — Select the country where the organization is legally registered.
- City/Locality — Enter the full name of the city where your organization is registered.
- State/Province — Enter the full name of the state or province where your organization is registered. If you do not have a state or province, enter your city information.
- Enter a valid path (such as \\myserver\admin\csr.req) to save your CSR on your computer, and then Finish. Your pending certificate request displays in the Exchange Admin Center.
