Just a note for you admins out there trying to make Traveler work using an SSL connection:
If you are having an issue connecting using SSL (HTTPS) but it works using HTTP, check to see if you have enabled AES encryption on your web site document.
Traveler uses Windows Mobile Active Sync to handle the connection it makes to your Domino server. Active Sync uses Windows Mobile IIS.
IIS does not support AES encryption.
If you enable AES on the security settings in your Internet Site document for Traveler, your Windows Mobile device will refuse to connect using SSL.
