I know this has been discussed a lot before, but I haven't yet been able to find a solution. For a few wondrous, beautiful days I had my smart (?) phone connected to my exchange server, and it was working like a champ. Then suddenly it stopped working (after some MS update, but I don't know if that had anything to do with it.) Now it won't work at all. I have gone over every Technet and Expert-Sexchange article I can find, and nothing is working. I've created the new virtual directory, and that hasn't worked either. I reinstalled the Small Business Server and recreated the domain, all for naught. I'm still getting the error in the title.
I've even turned off the required SSL, and it's not working. Is this just some update that has trashed the ability to connect to my exchange server over my smart phone (Windows Mobile 6.*)? I'd pay actual money at this point to get it working (not really, but still...)
