Before I could offer advice, I'd have to know who you're using for your email - is it AT&T, Gmail, Yahoo, ?????? Then I'd need to know what you're using on your PC to read/retrieve your email. Without knowing those two things, it's impossible to give any advice on how to set it up so it works properly. I currently use Gmail for my email and Outlook (part of MS Office 2016) as my email client to retrieve the mail from Gmail and display it on my PC.
Most (if not all) of the email providers have a web interface that allows you to read your email without downloading it to your PC. Have you tried that?
