I've been using Thunderbird for years but suddenly as of yesterday it's stopped receiving messages. First it told me my password was incorrect. Ever since then when I try to click "Get Messages," it simply has no response at all. Nothing happens. I went into my Thunderbird password settings, and upon seeing that the incoming-message password had for some reason reverted to an old, obsolete password, I corrected it and saved the correct one. I've checked several times and the passwords are correctly saved now. But this did not fix the problem. When I click "Get Messages," nothing happens. My Thunderbird is connected to my Earthlink account, which is working fine. When I go into Earthlink, I am able to send and receive messages as normal. So the problem is not with Earthlink but with Thunderbird.

I use Thunderbird on a Mac, where Gmail is my default email. When I try to send an email, it often takes 10 tries before it goes through, due to timeouts. How can I fix this?

I've been using Thunderbird on Windows 10 since last year sometime. Currently I'm on version 151.0.1.

I've 4 x mailboxes here and since yesterday, 3 of them show me an unusual message when checking for emails. I tried attaching a screenshot but although the screenshot uploaded, I couldn't find a way to insert it here. But the message says Unable to write the email to the mailbox and asks me to check if I've write privileges (which I have) and to cheek the available disk space.(currently 101GB free).

The message is happening 2 or 3 times each day and lasts for about half an hour, then everything works fine again. Has anyone else seen this??

In Thunderbird 151.0.1 [64 bit] I get the following error message: Error Inbox - inbox on .....[my email address] "There is not enough disk space to download new messages. Try deleting old mail, emptying the trash folder and compacting your mail folders and then try again." I did all of that, even went into windows disk cleanup to free up more disk space. I get the same error message. I have 3 email accounts in Thunderbird, only one account has this problem. When I use Outlook express I do not get any error messages but I do get a malicious email that AVG intercepts. So how can I purge bad email from Thunderbird ? Or what else may be going on and what else could I try ? I have deleted all old emails, in Thunderbird, I routinely delete old emails. Thanks alot Sam

Hello,

I can't receive any of my e-mails. I can send e-mails out now. Plus I can put in my password to log into my e-mail.  This has been a headache for me, I have been with Thunder Bird for years.

I also get a boxes that says : Unable to write the email to the mailbox. It says to make sure the file system allows me to write privileges, and I have enough disk space to copy the mailbox. I have enough space on my computer system and all. Another box that says my e-mail is being processed. Please wait until processing is complete to get messages. I did e-mail you yesterday on these issues. As I said I can e-mail messages out now also log into my e-mail with my password. Thanks, Chris

I have email [edited from public] @riverplazatravel.com purchased through Rackspace For days, on my emails through Thunderbird, I'm receiving emails but SENT emails disappear. They aren't showing in TRASH anymore, or SENT....they are disappearing and I have to check with my customer and they aren't receiving them. Big problem. Please help I've spent hours of research and dont understand much of that and so many are outdated. I've messaged and called various people. Your email was provided to me by Rackspace.

I have used Apple Mail, GMail and Outlook; i am hoping that Thunderbird will achieve (relative) zero inbox.

My objective is to create an inbox that observes established rules/filters and directs my emails into the appropriate folders. I was hoping that Thunderbird would achieve this objectives but I have so far been unsuccessful.

I would be happy to screenshare with an appropriate technician in order to resolve this issue as its becoming increasingly frustrating.

My Yahoo account on Thunderbird sees no email found.

My eMail Providers: Yahoo, AOL, Gmail.

AOL and Gmail(2 accounts) work fine. Only Yahoo doesn't respond. As you can see in the attached screen shot, it shows a "No Messages Found" message.

I have tried everything listed in the support page.

I'm sure it is something simple but I can't see it.

When I try to send an email via Thunderbird using my email account it errors out with a smpt error. I went in and deleted all the passwords (like it said online) to force a screen to pop up. Then I closed Thunderbird and restarted it with no success.

To whom it concerns, It just happened yesterday June 11,2026. I put in my password to my e-mail to open it and it stated that my e-mail account is being processed. Said to wait until processing is complete to get messages. I have never had this issue, I been with Thunder Bird e-mail for years. It isn't even showing my e-mails that I had in my inbox on my e-mail. If you can please help, I need my e-mail up and going. Thank you, Chris Note, it also said that Thunder Bird had crashed in a box, they wanted to know what page I was on. I am not understanding this.

Já há dois dias que eu não consigo receber e nem enviar emails e já tentei de tudo, já até desinstalei o Thunderbird e reinstalei e nada... Uso o computador e tenho outras contas, mas só a conta do sapo que tenho(marcaomulder@sapo.pt) é que está a dar problemas... Já nesta conta, se eu acesso o servidor(sapo.pt) está tudo a funcionar correctamente, sendo portanto o problema desta conta no thunderbird! Estou a contar com a vossa ajuda, pelo que muito vos agradeço!

• Já agora neste momento, depois que reinstalei o thunderbird, ainda não consegui reinstalar a minha conta: marcaomulder@sapo.pt

Cumprimentos!

I think I've tried everything to figure out why Thunderbird will not send emails.

Yes there was an update the last week of May to version 140.11.1esr (64-bit).

Yes the incoming and outgoing mail server info gibes with my ISP (Shaw) - added pix

Yes have done the necessary adjustments to Windows Defender and Firewall.

Yes I have increased mail.news.tcptimeout because occasionally have received message that "Outgoing server

• SMTP" mail.shaw.ca timed out. Try again. Yes I have indeed tried again.

Yes I have called Shaw and they will not offer any suggestions because TB is a third-party.

What's left to try? A version reversion? Thunderbird has been so stable for so long. I even considered Betterbird but it uses the same profile so............

Thanks.

I was hacked on 8th and received no emails until 11th. I think there may have been a couple of important emails but I can't find a way to retrieve them. Can you help please.
