The last new email I've received on Thunderbird for one of my accounts was on 5/13/2026 at 12:02 p.m. Every time I open thunderbird it tries to re-download the entire yahoomail account and times out. I have deleted all emails from the yahoo mail box from 5/13 and backwards. All spam emails have been deleted and the trash can has been emptied. Per online instructions I have also deleted the popstate.dat file, tried to repair the inbox file by right clicking on it, going to properties and clicking repair folder. I also tried to compact the folders, and have turned off my virus protection and nothing seems to be working. I also tried a new app generated password from yahoo. Current setup is pop.mail.yahoo.com port 995 SSL/TLS, authentication method = normal password. Any help would be greatly appreciated. Thank you!
