Sending of password did not succeed. Server error - please try again later.
I started getting this error "Sending of password for user xxxx@sbcglobal.net did not succeed. Mail server inbound.att.net responded: server error - please try again later." on 11/17/20, when TB updated to version 78.5.0. I'm aware that ATT requires a secure mail key, and tried to update to that, but still no luck. Both incoming & outgoing servers are set to normal password authentication. I'm using the correct ATT Pop server settings. Deleted saved passwords, restarted TB, tried to re-enter the SMK, but keeping getting the same error message. I can access my mail through att.net, so that's working, but really want to keep using TB. Any help would be greatly appreciated. OS is Windows 10 Pro.

Are you using Avast/AVG or ESET? There are several posts today about ESET blocking TB, and Avast/AVG can do the same if the Mail Shield and secure connection scanning are enabled.
If you are using ESET/NOD32 security/AV then probability is very high it is causing your problems. According to ESET forums, you should temporarily disable SSL on ESET until they solve the problem per https://support.eset.com/en/kb3126-disable-ssl-filtering-in-eset-windows-products?ref=esf - the problem is being reported by dozens of users https://forum.eset.com/topic/26517-problems-with-thunderbird-and-imaps/ https://forum.eset.com/discover/

No, I'm using McAfee Small Business version 16.0.
Disable the email scanning option and see if that makes a difference.
Those instructions aren't quite what I see in the business version--it doesn't give me an option to disable real-time scanning for certain areas, like email. It looks like it's either all off or all on (though, you can exclude certain files). So, I tried turning it off and checking mail again. Same error.
Suggest you contact ESET
Hi Wayne, not using ESET. I have McAfee Small Business.
