Welcome to Justanswer.com, my name is Dustin.
I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
To get started, I need to know what type of computer you are using, a Windows XP, Vista, Windows 7, Windows 8, Windows 10 or a Mac.
If its a Mac, please check the OSX version as follows, Click the apple sign at the top left of your screen, then click about this mac. And then where it says version, send that to me as a reply.
Also, how do you normally access your email, via a browser, internet explorer, safari, firefox, etc. Or using an email client such as Outlook 2013, Thunderbird, Mac mail, or windows mail?
Thank you for your response,
