domer, the reason it is working for you is BECAUSE you bought that SSL certificate. Your email address now uses SSL encryption, which the Pre is able to negotiate with just fine.
The problem remains for those of us who are NOT sysadmins and are connecting to Exchange servers which do NOT have SSL. We're basically just screwed because Palm completely forgot that any of us might exist, and I know I'm pretty freakin' disappointed about it.
This is a huge blunder on their part, plain and simple. Windows Mobile allows you to uncheck the "Use SLL" box. Apple's iPhone lets you uncheck the "Use SLL" box. If webOS HAD a box for "Use SLL", those of us currently unable to connect could simply uncheck that box, and be fine.
But, no. Instead, all we can do is wait for an update to the webOS which allows us to do what we damn well should have been able to do now.
This is totally ridiculous and completely unacceptable. I may just return my Pre before the weekend is over, so that I have working mobile email on Monday. Imagine that. A cellphone which was able check your corporate mail. It's sad that I would now consider such a device an "upgrade" from the worthless little pebble I woke up at 5am to buy, like a damn fool.
Phfft. This is what we get for being early adopters. This is what we always f'n get, and we never f'n learn. The next time I'm forced to watch a Lifetime movie about a woman who keeps going back and back to the man who abuses her, I won't wonder why. I used to ridicule her, but now I realize I'm just like her.
