Setting up an ATT email account

Thunderbird Anders
atErik beantwoord

I have two emails accounts setup in Thunderbird but when I try to setup an att.net email account, I get an error message saying the "sending of the password did not succeed. Mail server inbound.att responded:Server Error - Please try again later."

I have tried this numerous times over several days with setting up the account automatically and manually. I have a friend with a Thunderbird account using att.net, which stopped connecting and exhibits the same errors with trying to access the account.

I know that the password is correct and I am about to setup the account in Windows 10 Mail and also able to access the account through a browser.

adjust your AV (AntiVirus) / SS (SecuritySoftware) software , you may need to disable specific "mail-protection" option in it , and keep "Scan file on access" option enabled. more info.

if that does not solve, then to solve it, we will have to first check/verify mail-server settings: you may also see this page for more info on AT&T & AT&T-Yahoo, etc. basically goto ATT web mail access site, generate SMK (secure mail key) code, & use that as password in TB (Thunderbird). ATT mail-account with SMK , should use "Normal Password" auth-method, via SSL/TLS security. imap uses port 993 , pop uses port 995 , smtp uses port 465. if you want to use OAuth based auth-method, then select OAuth "auth-method" & enable Cookie.
