Problems with email setup

New Droid DNA owner here, converting from iphone...literally just got it an hour ago. Haven't downloaded any additional apps or such, just trying to set up my phone basics - most importantly my email.

I had to manually set up my email accounts - at first I wasn't sure if they were correctly set up because the connection would often time out/be unable to connect even though I am in a location with full service bars and be unable to verify my credentials - the exact message I get is "cannot connect to the mail server to verify your account information. Your server is not responding". It gave me the option to keep going though, and I am (pretty?) sure I got my emails set up because I can send emails from my phone perfectly fine [checked from the computer if i received the emails i sent from the phone]. Problem is, I can't receive a single email on my phone. My inbox is totally empty and I keep getting a "connection timeout" alert when I try to sync my inbox.

What is the fix for this?

EDIT: unlinked and relinked both email accounts. Got one of them to work, but the other one still isn't working

It sounds like your settings are wrong for some setting - maybe wrong incoming mail server, maybe wrong port number or security setting. Check your setting on your PC app if possible otherwise double check with your mail provider
