Starting on the 17th, two of my accounts suddenly said (see image) "server error try again later." However I have multiple Yahoo accounts, all Prodigy.net, from the old days, and the only two that don't work, are the ones that I signed in using the new AT&T / Yahoo. The accounts that have never been signed in online, work fine and download my POP mail from Yahoo. There's nowhere in Thunderbird (that I see, I might be missing the how to) for me to add OAUTH (see image) I tried to find Yahoo support which is absurd. They offer pay subscription for support? All the pages for online yahoo mail are now "Currently from AT&T Yahoo mail and any support link, takes me to AT&T where they ask questions, like what's your AT&T account, what's you AT&T phone number, and I have neither any longer. Then the nearly impossible to understand person, who barely speaks English says, delete your account. What? I've had this account for 17 or more years. It's my main contact. Then I explain for the 30th time, I can get my mail online, but not on my phone or my desktop. She says, ''wait 24hours...'' Wait 24 hours for what? ''In case something changes.'' But we did nothing why would it change? ''Wait 24 hours.'' But I've been waiting for three days. Yes I have cookies enabled. As far as I can see, I changed nothing, all accounts have identical settings. It seems like Thunderbird and the users have a better idea of what's going on, than the provider. :-) I read and read, and I still don't understand the oauth and I can't set it for inbound.att.net so I'm missing something? But odd that of six accounts, only two stopped working on the 17th, the others I get my pop mail just fine. I suspect that somehow, logging in to the new AT&T changed something and now my two used accounts, not the useless ones, don't work. Can You Help Please? https://i.postimg.cc/0QF9P6zV/yahoo-mail-error.jpg Is this just me or are there a flurry of people hitting this Server Error message? Thanks for any ideas or help.
