Installing your SSL: Microsoft Exchange 2007

You will receive an email with your SSL certificate and Intermediate certificate. Please follow the steps shown below to install your SSL certificate.

Import the Intermediate certificate


First, copy the Intermediate certificate from the email you received and then follow these simple instructions:

  • Copy the intermediate certificate from the body of the email and paste it into a simple text editor of your choice, such as Notepad.
  • Save it as intermediate.cer on your desktop.
  • Open MMC.
  • Select File, Add/Remove Snap In.
  • Select Add.
  • Select Certificates, Add.
  • Select Computer Account, Next.
  • Local Computer, Finish, Close, OK.
  • Select Certificates, Intermediate Certification Authorities, Certificates.
  • Right-Click Certificates, All-Tasks, Import.

The Import Wizard should now start. Next, just follow the instructions to import the intermediate certificate and close MMC.

Import the SSL certificate


Copy the SSL certificate from the email and then save this as mydomain.cer to whichever location you want.


Next, open the Exchange Management Shell and run the import and enable commands together separated by a pipe character:

Import-ExchangeCertificate -Path C:\mydomain.cer | Enable-ExchangeCertificate -Services "SMTP, IMAP, POP, IIS"


The services can be any combination of these values: IMAP, POP, UM, IIS, SMTP.


You can verify that your certificate is enabled and running by using the following command:

Get-ExchangeCertificate -DomainName mydomain.cer


In response to the above command you should see the certificates thumbprint, an abbreviated list of the services and mydomain.cer. You can re-run the modified Enable command with the certificate thumbprint if your certificate isn’t enabled correctly.

Enable-ExchangeCertificate -Thumbprint [paste thumbprint here] -Services "SMTP,IMAP, POP, IIS"


Finally, reboot your server and then test your certificate is working properly by connecting with IE, ActiveSync or Outlook.

Important: Do not use the Certificate snap-in to import the certificates for any service on an Exchange server. Using the Certificate snap-in to import certificates on Exchange servers will fail. Therefore, TLS or other Exchange certificate services will not work. Learn more about this by visiting the following page:
