The Evo has been handling my Time Warner Road Runner account (Exchange Server?) without a problem since day 1 (6/4/10)...until recently. The only thing that has changed is the emails are not being removed from my phone once they download onto my PC. I didn't change any settings - and can't find any to change in regard to that. Any idea what I can to do to get them to automatically delete from the phone upon download to the PC?
Time Warner / Road Runner does NOT give you an EAS account. You're using pop3--ActiveSync will do what is sounds like, sync all your email devices, not delete from server.
It sounds like you want email to not show up on your PHONE. Which sorta tells me what you want to change is on your computer. Whatever client you're using for pop3, you can change the setting to delete mail on the pop server after downloading.
I recommend that you don't use pop3 at all. You can use your gmail account (the one you have on the phone) and go to Settings, then have it check the pop3 account. Get rid of the email client on the computer, and stop using pop client on the phone. Use the Gmail web page to access your email everyone, from the gmail app on the phone, from the home computer etc.
If you want to keep this email distinct from your existing gmail (for simplicity sake, because outgoing mail will still originate from the SMTP--Road Runner--email servers) you can create a second gmail account just for the purpose of checking your pop3 email.
Welcome to the 21st century and cloud... =P pop3 email is so 1996.
