This is an issue that I've had all across 2.0, 2.0.1, and 2.0.2. For any of the mail accounts that I have synced on my phone, I will intermittently experience an inability to send an email. At times I will hit the Send button and the message will disappear as per usual but it will not appear in an Outbox nor do I see it in the Sent items folder -- it will just vanish. Other times the mail will sit in the Outbox and will just refuse to send. Anyone else experiencing these problems/know how to fix it/force resend a message?
