This Process demands, that the existing certificates has to be replaced by new Certificates.

To this your cooperation is essential. To due date 05.08.2017 the old certificates will be deactivated and removed from the Skype For Business Platform. After this the new Certificates will be installed.

Consequently it’s of utmost importance, that you add the CNAME Validation Hostname entries to your domain(s), as soon as possible.

Please add the following CNAME Records to your DNS to guarantee a successful validation:
