One of the options which was missing in the first edition of the script was to check if a certificate is self-signed or not. By default a self-signed certificate is installed on an Exchange CAS Server. The problem with this kind of certificates is that other servers won’t trust it.

If this is the case there are two options:

  • import the self-signed certificate on the other servers, in this case the Lync Front End;
  • install a valid certificate;

The first option is not  really the way you want to solve it but sometimes you don’t have another option.

Below the changes which have been made in the script:

  • check if a self-signed certificate is installed;
  • option to export the self-signed certificate;

If you got any tips or suggestions please leave a comment.
