Motorola Droid X :: Why Won't Email - Hotmail Send

Up until Sept 19, I was able to either hit reply, compose new, or send emails from links/apps without any issues. I use Hotmail and go thru the stock email client on the phone. All of a sudden, every time I try to send an email, it errors out and I get a notice saying it wasn't sent. The phone doesn't give a reason, and the only option is to delete the message. Did the Froyo update mess something up or what? I haven't changed any of the settings on my account and only occasionally had this happen before, but now it happens on every outgoing message.
