Important: This article applies to Network Solutions customers only.

At this time Network Solutions® does not directly offer a Unified Communications Certificate. You may secure a UCC from our partner Sectigo by contacting our Support team. Your existing mail.company.com certificate.

If you choose not to use a UCC, you can follow these instructions, you can obtain two certificates for your environment:

  • Your existing mail.company.com certificate 
  • A new Autodiscover.company.com certificate

As long as you can allocate the correct certificate at the correct time you are able to connect with no issues.

Doing this simply requires that you set up two virtual servers on the CAS server. One services Autodiscover.company.com on one IP address and the other services the remaining web services on mail.company.com using a different IP address.;

Note: Each virtual site setup will need its own IP address.

Here are the steps:

1. Obtain a separate certificate for mail.company.com and Autodiscover.company.com.
2. Create a new virtual server in IIS on the CAS.
3. Create a new Autodiscover virtual directory in the new virtual server and remove the old one.
4. Assign separate IP address, and certificates to each Virtual server.
5. Configure your internal SCP to point to Autodiscover.company.com.
6. Configure your Internal and External Service URLs to point to mail.company.com.
7. Make sure that your configured URLs will resolve internally and externally via DNS to the expected IP address for each of the services.
 
You have now generated your CSR on Microsoft® Exchange 2007.

In this configuration, internal domain member clients find the SCP to make the connection to Autodiscover.

External clients find Autodiscover.company.com using DNS to make the connection to Autodiscover. In both cases, the clients are referred to mail.company.com for the actual Exchange Services.

Installation Instructions

You will have received your certificate file from us, usually named your_domain_com.cer. 

Alternatively, you may have received it as several files: your_domain_com.crt and intermediate certificates EV_NetworkSolutionsEVServerCA2.crt and NetworkSolutions_CA.crt. The root certificate EV_NetworkSolutionsCertificateAuthority.crt may also be provided. 

Follow these instructions to copy the file(s) you received to the server:

1. Open the Exchange Management Shell. This is done by clicking Start > Programs > Microsoft Exchange Server 2010 > Exchange Management Shell.
2. Type and run the following command. It should all be entered on a single line.
Import-ExchangeCertificate -Path C:\your_domain_name-or-order_number.crt | Enable-ExchangeCertificate -Services "SMTP, IMAP, POP, IIS"
3. The certificate is now installed. You may also need to follow the next steps to install the intermediate certificate(s) on the server.
