How to Install an SSL Certificate on Skype for Business

Skype for Business

This guide offers quick instructions on how to install an SSL certificate on Skype for Business (formerly Microsoft Lync). The last part features useful tips on where to buy an SSL certificate for Skype for Business.

Please note that Microsoft recommends using UCC certificates as it’s often necessary to secure multiple subdomains for different machines. If you’ve already applied for your SSL Certificate and received it from your CA, feel free to skip part one and jump straight to the installation steps.

  2. Follow our step-by-step tutorial on how to generate CSR on Skype for Business.

Install the SSL certificate on Skype for Business

After your CA sends the necessary files to your inbox, download the ZIP folder and extract its contents on your device. Skype for Business requires SSL files to be in PKCS#7 (.p7b) or PKCS#12 (.p12 or .pfx) formats.

If you receive your cert in another format such as PEM for instance, you can convert it via OpenSSL or an external conversion tool. For more information, check our guide on SSL certificate formats.

You should know what particular service you want to encrypt using the -Type argument. For more information on services, check Microsoft’s documentation.

To import a PKCS#12 (.p12 or. pfx) file, enter the following command in your Skype for Business server powershell, replacing the path:

Import-CsCertificate -Path "c:\your_certificate.pfx" -PrivateKeyExportable $True

Locate your SSL certificate

First, you need to identify your SSL certificate via the Get-CSCertificate cmdlet and then sort the results with the Where-Object cmdlet.

Enter the following command to list all available certificates:

Get-CsCertificate

To find your particular certificate enter the following:

Get-CsCertificate | Where-Object {$_.Subject -eq "CN=yourdomain.tld"}

Enable your SSL Certificate

To enable the certificate for default and web services roles run the following command:

Set-CsCertificate -Type WebServicesExternal -Thumbprint "B142918E463981A76503828BB1278391B716280987B"

If your search command returned just one result, you can enable the certificate via the following command:

Get-CsCertificate | Where-Object {$_.Subject -eq "CN=domaine.tld"} | Set-CsCertificate -Type Default, WebServicesInternal, WebServicesExternal

That’s it. For more information, please refer to Microsoft’s official documentation here and here.
