Exostar LDAP Proxy/Secure Email Set-up

It is recommended both Email Encryption set-up and Certificate Discovery steps are completed to enable users of Exostar’s LDAP Proxy / Secure Email  services. Certificate Discovery requires connection to Exostar’s LDAP Proxy Service via port 389. This may require additional configuration by your IT infrastructure groups depending on local policy and controls. For Lotus Notes and Mozilla Thunderbird, contact Exostar Customer Support. You must provide Customer Support with your email client version. Please select from the different versions of Outlook below.
