Unified Communications

For MS Exchange and Office environments.


Unified Communications

Unified Communications (or Exchange SSL) certificates are built expressly for the Microsoft Exchange 2010/2013 (and up) and Microsoft Office Communication Server 2007 environments. These certificates will secure up to 100 domains and provide unlimited server licenses. They provide validation of the organization behind the website (making them suitable for business sites that collect sensitive customer data) and can be issued in two business days or less.

Due to the high level of validation provided by Organization Validation (OV), certain paperwork is required before these certificates can be issued.


Business Registration

Your business registration needs to be authenticated. Comodo will check to see that your company is legally registered by verifying your business profile.


Company Representative

This person must currently hold an executive position within the company (CEO, CFO, COO, etc.)


Whois Contact Info

To make the certificate issuance process faster, be sure you have the correct contact information on Whois for your domain.



To verify Whois domain data, WhoisGuard must be turned off. This information will not be available otherwise.

What Do You Get With Unified Communications?

domian validation
Organization Validation In addition to domain ownership, Comodo checks business registration before issuing a certificate. This gives more assurance to site visitors.
Unlimited Server Licenses With Unified Communications SSL from Comodo, you get unlimited server licenses, meaning you have the option to install the certificate on as many physical servers as you wish.
single domain security
Multi-Domain Support Comodo multi-domain certificates secure three domains by default (one primary common name + two subject alternative names [SANs]). With additional SANs, you can secure up to 100 unique domains.
free site seal
Static Site Seal Site Seals are free SSL logos provided with your certificate. Display the static seal anywhere on your site as an on-going visual reminder to customers that your site has Comodo SSL.
refund policy
15-Day Refund Policy Your satisfaction is important to us. That's why there's a 15-Day Refund Policy in place for the Unified Communications SSL certificate.
no paperwork
Timely Processing Though there is paperwork involved with this level of verification, Comodo will issue your certificate in not more than two business days.

A CSR generated on your web server for your domain name.


● SSL certificates must be installed on your web server. Therefore, an end-to-end SSL installation support is possible only in cases where the domain name is hosted with WebHostingWorld. If the domain is hosted with any other provider, please contact their support team for assistance with CSR generation and SSL installation.
● Selected orders may be flagged for an additional "Brand Validation" procedure by the Certificate Authority. This is a necessary security measure. If the order is flagged for Brand Validation, SSL issuance will be delayed for a period of time deemed necessary by the Certificate Authority.
