Here's the deal - the Gmail app was working perfectly for me, but I wanted to use the HTC email client. I had my account set up on both, with 15 minute polling on the HTC client, and this worked fine. However, I wanted push email while using this client, so I set up Exchange activesync using m.google.com for my gmail account. I noticed almost constant activity from the activsync, the phone got quite hot in a short time, and the battery drained at an amazing rate. So I decided I didn't need ativesync, and I deleted the account. This is when the problem started. My gmail app now refuses to send out any email. When I try, it says "sending" in red, but it never does. What are my options?
