Hi, I registered a global web form for a content class of my own on a backend server. As long as I access an element of my content class with an *http* URL from our OWA front end server (Exchange 2003 SP2) my form gets displayed. But as soon as I use *https* URLs I get this error in the browser (server name renamed): ------- The page cannot be displayed <snip/> HTTP 500.100 - Internal Server Error - Forms Renderer Error Web Storage System Forms Rendering Engine <snip/> Error Type: Server Error Bind to session failed for 'https://myex.somewhere.org/exchange/test/inboxx/hello%20world.EML', hr=0x80040e19. ------ Does anybody know how to make this work over https?
