These are the two error messages I get from my android phone and Fire Tablet. Gmail works fine, and ATT email works on my computer. No operating system updates or changes for months. But just tonight, email won't work. ATT won't help unless I pay for some special service-I already pay them enough. I did nothing to cause this, but suddenly email doesn't work/

This just happened to me too! I un-synced it from my Galaxy S5 because I realized I wasn't receiving any new emails the past couple of days and tried to re-sync and now it says it cannot safely connect to server. I have been using this email on all of my androids for years!!! This is very annoying!

Had same issue with my Galaxy S5 recently. It was also working for years up until a couple of days ago. I use the default Samsung mail client to get my AT&T mail. Clearing out the application cache or powering off the phone and pulling the battery didn't change anything.
I ended up deleting the account and recreating it. At first I got the same error message when trying to configure it. I then changed the security type on the incoming mail settings from the default SSL to SSL (Accept all certificates). Researching the "Accept all certificates" option I found that choice will automatically accept all secure certificates as opposed the SSL option which will (or is supposed to) ask for confirmation for secure certificates. After making the change I was able to get my email successfully. I also made the same change to the security type on the outgoing mail settings. I'm thinking just making the change without deleting the account would have also worked.
Obviously something has changed on the back end.
Hope this helps.

It worked! I've spent the last 2 hours searching Google, resetting accounts from pop3 to imap, and pulling my hair out to try to get this fixed. I don't know if it will work if your incoming/outgoing settings aren't already on imap from pop3 and you're dealing with Outlook on laptop (since mine is changed now), but I created an account here just to say THANK YOU! Now to get my Outlook to sync, now that it's finally connected to the server *bangs head*...

You are wonderful, it worked for me, as well. Two days with no email, and I was ready to go out and buy a laptop, because we are going on vacation, and I had nothing on which I could view email. Thank you, thank you, thank you!

I have been pulling my hair out for the past 2+ days trying to get my att.net email to sync on my Android. I knew it was an att.net issue b/c my gmail.com email was working perfectly. Finally ran across this discussion board and wanted everyone to know that antwerpx solution #2 (i.e., fixed the issue without having to delete the account and recreating it) worked for me (see his posting at Jul 27, 2017 7:23 AM). All I did was changed the "Security type" from "SSL" to "SSL (Accept all certificates)" in both the INCOMING and OUTGOING server settings. Once I changed both of those settings, it only took a few minutes for everything to begin syncing. Note: this fix only worked after changing the Security type in both the INCOMING and OUTGOING server settings.

So are all of us having the exact same issue at the exact same time? My email just stopped working on 7/25/2017 for no reason. Your solution worked for me too. Thank you so much for taking the time to post this solution!

The suggested solution of changing the "Security type" from "SSL" to "SSL (Accept all certificates)" in both the INCOMING and OUTGOING server settings worked for my Samsung Galaxy5 immediately. To the person who posted the suggestion, you are a genius for those of us who ARE NOT tech-savvy nor want to be a device-addict. THANK YOU!

It didn't work for me This is so annoying. I tried it but it ends up say Authentication failed.

Mine stopped working on 07/25/17 too but this didn't work for me. I get a message: Unable to verify account information - the email server (inbound.att.net) is not responding. You can continue the setup process, but you will not be able to send or receive email until your account has been verified by the server. If I continue, it brings me to outgoing mail server settings in which I change the SSL then next then I get message: Setup could not finish - Authentication failed.
