I tried out Xpressmail on my Cingular 650. For various reasons, I've decided not to use it. I deleted the account from the Treo, yet it seems like the program is still periodically checking for mail. The reason I've thinking this is when I log into my email account from my PC, messages appear as already read. What is the best way to cancel out of Xpressmail to remove my accounts completely?

Any thoughts?
