SSL Certificate error Outlook 2013

Hi,

this certificate looks like it's from the Web-Filter (Netscape Comment: Generated by...)

Go in WebAdmin to Web Protection --> Filtering Options --> HTTPS CAs and download the Signing CA Certificat.

Import this for test on your local computer to the computers "Trusted Root Certification Authorities" and check if the Popup still persists.

If it's gone (should be...) create a GPO on your Domain-Controller and push it to your clients (and of course "not exportable").

We don't want to import the UTM 9 CA Certificate.
