  • Open MMC.
  • Select File, Add/Remove Snap In.
  • Select Add.
  • Select Certificates, Add.

  • Local Computer, Finish, Close, OK.
  • Select Certificates, Intermediate Certification Authorities, Certificates.

The Import Wizard will start, follow the instructions to import the intermediate certificate and close MMC.

Import the SSL certificate


Copy the SSL certificate from the email and save this as mydomain.cer. The name and location of the file are not important.


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.


To verify that your website security certificate is running and enabled run 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. If your certificate isn't properly enabled, you can re-run the modified Enable command with the certificate thumbprint:

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


Reboot your server and test your certificate is working 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. For more information please visit
