Desktop Thunderbird no longer downloads mail from Yahoo though it did until 2 weeks ago or so. Now when checking for mail, I only see a "Local Folders: Checking Inbox for new messages" (screenshot) that eventually disappears after a while with no download. I can still send messages out from Thunderbird through Yahoo. I have done the "Please check the following before asking for support" : 1. I can log into my Yahoo account via the web and am using the same password 2. I only have one Yahoo account; all the other accounts work fine 3. I can send mail from Thunderbird through my Yahoo account with no problem 4. OAuth2 is active and can successfully establish a secure connection (screenshot) 5. Cookies are enabled with no exceptions (screen shot) 6. I do not use a VPN 7. Version is 151.0 (screenshot) 8. I checked the Error Console messages when Checking Inbox was active (screenshot) but do not understand it

I blocked out information on non-Yahoo accounts and email subjects on screen shots

I get the following message when I try to download emails "Unable to write the email to the mailbox. make sure the file system allows you write privileges and you have enough disk space to copy the mailbox

I have been using Thunderbird for YEARS, with 3 separate email accounts. Great product.

Just recently, with out warning, my [edited from public] @ sbcglobal.net account stopped being able to send email. I can still receive emails. I have not changed any outbound setting. Any help appreciated.

How do I add my Comcast email account to Thunderbird now that it has switched to Yahoo? When I try to add it all I get are the Comcast mail servers in the setup program to add an email. When I try to edit it and change it to the Yahoo mail servers it does not work. I have used Thunderbird for many years and Firefox for a browser. When I started on the internet I Used Netscape. Firefox and Thunderbird were started by Netscape programmers if I remember right. I love both Thunderbird and Firefox and don't want to change but the way it is now I cannot use Thunderbird for email. I have tried both Pop3 and Imap setups. Neither will either allow me to set up my email in Thunderbird to get email from Yahoo. I do not like the Yahoo Website for email.

Once in a while, when I download email, Tbird fails accessing outlook.com. The message is in the attached image. If I redownload, it works. Any Ideas? P.S. this has happened with several versions of Tbird... Thanks.

I am no longer getting emails on Thunderbird on my computer though I do get them e.g. on my iPad, and I can email out. Is that a problem with Thunderbird or with Bell my service provider?

I can send email via my laptop, which is visible on my mobile devices, but new mail has not downloaded to my laptop since May 25, after being notified by Google that I had to recover my account. Everything works fine via Gmail.

Later this week I'll need to copy a bunch of old emails to someone (some of them received by me and some sent by me). Does Thunderbird have such a feature or is the easiest way to print them on paper and resort to snail mail?

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!

Have not been able to receive email on my primary account (I have 3 accounts) for 3 days now. Windstream has been no help and seems to have lost hundreds of important files. My 2 other accounts work fine. HELP!

Thanks in advance. I'm trying to get Thunderbird setup with an outlook.com email address. All the default server settings look fine. I know the email address is good since I can login via a web browser. Cookies enabled and all the other recommended settings including app password. Yet it keeps saying Unable to log into the server. Has anyone successfully done this with the latest version of Thunderbird. I'm on Zorin 18 Pro.

With previous computer (Winidows 11) I've been able to send an email from WITHIN Word, but now I get error message "Word couldn't send mail because of MAPI failure." Any idea how I can fix this? Regards, David, running TBird version 151.0.1 (64-bit)

Hi everyone!

I'm trying to log into my email account on the domain example.com via SMTP. The email account is with yandex.ru. When I try to authenticate, it says the SMTP password is incorrect. I decided to try through Outlook, and it worked. What could be the issue?

I sent an email to my mechanic today and another site attached a CC to their Website. It is weird I didn't send an email to them support@bloominto.co, yet I received a reply and there was a CC to my mechanic in it.

How is it possible?

I keep entering my details but it does not work, I have sent the tested the settings and they are OK nbut the system keeps asking me to re enter password .I have not changed any passwords and only want a pop3 account to send and receive <X@hainsworthsboatyard.co.uk> I have my own server and domain name through Maxer via C panel .I use microsoft outlook OK but cannot alter my e mail box size
