Hi Siegfried,

AFAIK once you get the "It works" page, you should be good.

I have a working activesync setup, however I have never been able to make a connection from Outlook (I only briefly tried at work, outside my LAN). I can't prove it, but I suspect Outlook requires a https connection with a valid certificate, signed by a known CA. Or maybe you can import a root CA into IE's certificate store and Outlook will pick that up as well. I wasn't able to try this due to lack of permissions.

My certificate is self-signed; this is the only reason I could come with why this wouldn't work with Outlook. In the end, I gave up, since it's no big deal for me. Maybe you can test with a mobile phone or some other device, so that you can at least establish that it works with some clients.

It could be interesting to see if Outlook is attempting to make a https connection, or if it's actually connecting over http. That might give you some clues as well.

Good luck,

Paul
