The 6/14/22 current Thunderbird 91 did not function with the manual configuration settings which Yahoo has proferred elsewhere, I did what I needed with Protonmail Export/Import program it has for it's paid users, I could have paid crappy Yahoo but why would I do that, that is their sole reason for not making it convenient themselves, another program for Yahoo Mail fetching failed, though yet another program called Mailbird is probably best supported of all and it did function properly, yet it does not do the simplest downloading and exporting that common sense would have it doing, so the appropriate course is to use a competing product from the one that leaves you in this mess, and that as they say, dear friends, is that.

i am using Thunderbird ver: 104.ob2 32bit. I have same problem with password and when I enter the password, it works some times and some time it fails with imap connection any solutions?
