I have a Sprint HTC EVO, which I like. I have a strange problem on it. I have configured a couple of email account (Exchange, and Yahoo). Every few days, my email accounts a automatically deleted from the Account list. Furthermore, the account is not deleted gracefully, so I cannot add an account with the same name, as the email app thinks that account already exists! However, I do not get any new emails, nor do I see that account in the Account list. Browsing the web, it seems like others have been seeing this issue since 2009! Is anybody aware of any fix to this problem?
