Att Mail Mail Server Inboundattnet Responded Server Error Please Try Again Later
Mail server inbound.att.net responded: Server error - Please effort again after.
For a month now one of my v electronic mail addresses, which formerly worked just groovy, returns this message, upon opening Thunderbird: "Sending of password for user (my email address)@att.net did not succeed. Mail server inbound.att.net responded: Server error - Please try again later." I've checked both Tools/account settings, and Tools/options, and also checked my (hidden) passwords for all 5 accounts. I tin't observe anything Dissimilar on the one that doesn't work. When I attempt SENDING a message from this same problematic email account, I get this message: "An error occurred while sending post. The mail server responded: Asking failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and endeavour again." I've tried running in Safe fashion, but that does not solve the problem.

I think the settings for all your accounts are becoming increasingly complex, with all the conflicting communication, that I'd suggest you create a new profile, and add together i business relationship with the AT&T recommended settings, and use a secure mail cardinal in place of the regular account countersign. Confirm that the business relationship can ship and receive, so add another account once the first ane is working. Requite each business relationship a distinct Account Proper name, and each smtp a distinct Clarification. Have each account transport through an smtp server which has the same User Name and password (mail key) as the incoming account. (Select the account in the left pane of Account Settings, prepare the smtp in Outgoing Server (SMTP) in the right pane).
In one case you lot have two accounts working properly, add the rest in the same way. Later, you can always transfer data such every bit Local Folders, address books etc. from the onetime profile to the new i. Assist/Troubleshooting Information, nigh:profiles to create and launch multiple profiles.

perhaps iv accounts are in a western Usa cluster of servers and the other is in an eastern states ane. Connecting to a server name at a large provider is not a one to one human relationship. the load balancer could dump your connection on any of a number of machines. If one is wrongly configured or updated ahead of the rest, then you lot will come across unlike results with identical settings.
Accept y'all tried checking on web mail that the business relationship is actually active? I take received some truly weird error letters over the years when the provider suspends the account for some reason.

In that location was an issue some months agone I recall where 'mailbox unavailable' appeared when the sending business relationship had a Reply-to Address in Account Settings that was dissimilar from the sending address (which it ordinarily is). The Answer-to Address wasn't 'authorized' on the provider's webmail site. A possible factor here?

There is likewise this featherbrained Yahoo push to remove less secure apps and enforce app passwords.
Try changing the server name in outgoing servers (SMTP) from the ATT provided one of outbound.att.net to smtp.mail.yahoo.com authentication method in outgoing servers (SMTP) to oAuth2.0.
I would non suggest the change, except in another thread hither this week, yahoo support told an ATT customer that was having certificate issues to change the incoming server name from the ATT i to the yahoo i, so if it works for incoming, it nearly likely works for approachable. No impairment in trying anyway.
If that works, mayhap consider using the yahoo server settings for the incoming as well, that style yous can use oAuth2.0 authentication for everything and the whole e-mail mess becomes simpler.

Dear SF, Thanks for the data. I spent awhile wandering around my webmail site, just couldn't find annihilation that was a "Reply to" selection.

Hi all, I have used Thunderbird working happily for several months with a unmarried TB client working from GMail using POP3 and stable settings and countersign(s). So yesterday I became concerned afterwards listening to a fraud result on the BBC radio and decided I should change my GMail password, which I did. Since yesterday I now get my emails from GMail on my iPhone (which was e'er the case) but Thunderbird repeatedly asks me to enter the countersign, then says "Mail server popular.gmail.com responded: Username and password not accepted." I have tried removing the TB account and re-adding information technology. I have tried various Port numbers as more than one are indicated. As well re-changing my Google single sign-in password. What else should I do please? Your advice will be much appreciated. Geoff (in Kent UK)

Google are going to remove the less secure apps option entirely. They will exist starting this in June with g-suite.
And so I doubtfulness they will react at all. Thunderbird all the same does need to react, so folks tin can all the same access their mail without the setting.
