Can't Get Email: Changed AT&T PW, Changed Email Client PW, Cannot Get Email
(Running Latest Thunderbird on Latest W10) I changed my AT&T PW. No problem signing in to AT&T or accessing my email directly on AT&T/Yahoo. I then changed my AT&T PW on Thunderbird. But now Thunderbird cannot get AT&T/Yahoo email. Instead I'm continually notified that there's a "server problem." The exact message is as follows: "Sending of password for user xyz did not succeed. Mail server inbound.att.net responded: Server error - Please try again later." I've checked and triple checked my new PW as entered into Thunderbird. It is correct. It is the same as the new AT&T password. Since I couldn't get my AT&T email, I changed the new password back to the old password. Still couldn't get the AT&T email. Still got the same message. What should I do?
