I can not down load Emails from Yahoo to Thunderbird. Every things was fine as of Aug 26th. On Aug 27th with no changes to any system settings the Yahoo Emails would not down Load. I am running Win 10 on my system. I disabled the antivirus. Reloaded Thunderbird - no effect.

I have since deleted Thunderbird and then reinstalled  latest version of Thunderbird (154.0) .
I re-entered my password. I checked the OAuth2  settings and they are set as described in the support article "OAuth2 Authentication for Yahoo, AOL and ATT". 

Message bar at bottom of Thunderbird screen shows: Myaccountname@yahoo.com:Downloading message 1 of 7 The emails do not down load - then after a few minutes - a no messages to download message flashes and then blank - nothing

I am out of Ideas. Anyone?

re: OAuth2 Authentication for Yahoo, AOL and ATT

My settings selections don't really follow your help descriptions to the letter,so..., also, I already have 2 accounts on 2 platforms and they seem to already be configured with SMTP outging servers using OAuth2.

I'm confused since I'm now on 140.8.0 and have not needed to change a thing, contrary to expectations set from T-bird app popup warning and Mozilla article.(?)

Created new yahoo mail IMAP (PKCE) account using Thunderbird account creation. All seemed to work well. However, new account does not receive mail from "some" other IMAP and POP accounts in testing, including from TB Pro. Strangely, mail sent from oldest POP accounts works. Mail from newer POP gmail and TBPro accounts is not received. TB 149.0b1 Windows 11

Thunderbird worked well on windows 10 until the first of this year. When I write an email or re-send (some) emails, the email shows up with a lot of the letters garbled like code. Also a number of *s at front and end of sentences. All three of my computers are suffering the same maladies. All windows 10, Norton, Malware, same problems. I have tried every change that I am allowed on Thunderbird, and have use the compact function and repair folder function, to no avail.

Is it possible the problem is related to a problem with Thunderbird and ATT or Comcast, or my modem/router?
