The error message indicates that there is a certificate error. You can test it by opening in Internet Explorer (on the server where LOGbinder for Exchange is installed) the Exchange URL that you specified in the LOGbinder for Exchange input. It should open without a certificate error.
This certificate error often occurs when a self-signed certificate is used. Please add the certificate to the trusted root store solve the certificate error.
Also note that because of limitation imposed to Exchange 2016 auditing, LOGbinder currently does not support Exchange 2016.
