I have three email accounts. One is with a btinternet.com domain, and Thunderbird 153.2.0 has started not fetching emails from it while getting all the others. I've removed and reinstalled the account and things work fine for a few days but then it stops again.

All the security settings, etc., seem correct, and I'm not getting any error messages, just nothing happens.

Any thoughts from out there?

now i am getting mail but my dad and my brother both said they are sending mail and it says undeliverable I tried sending to my self and it came through I have Thunderbird through Comcast. i see mail in Comcast that is coming through so i do not know why. the only thing i could think of was they tried yesterday when the update was going through i received a mail at 7.15 this evening so i have no idea why it would bounce back did nothing to change anything

Hey guys,

So I am trying to create a rule that will delete emails on the server that are 360 days or older.

I know you can go into settings...

>> leave messages on server >>>>>>For at most ,,,,,,,

But from what I have read that only deletes emails on server from when they were downloaded into thunderbird.

I am new to thunderbird so that wont work for me.

So I went into message filter....thinking this would work

>>>>>age in days > is greater than > 360 days >>>>>>>>>>>Delete From Pop Server

But nothing happens???? Help!

Your input is appreciated

Today I started to receive this error message when I went to download emails from my aol account to thunderbird. This is the first time this has happened. "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." We have plenty of disk space so that can't be the problem. I could see many other people are experiencing this problem and there seem to be a variety of solutions depending on the circumstances. We are on Windows 11, we don't have McAfee installed but us Norton antivirus. I tried checking the settings, I've rebooted, and not sure what else to do. I can't remember some of the other comments I read. However, I am not technical and couldn't understand most of the suggested solutions. How do I get remedial help to figure this out?

I have three separate Yahoo email accounts. I set up Thunderbird to link to each Yahoo email account separately. It worked fine for a year or more. On 5/25/26 one of the three Thunderbird email accounts stopped downloading emails from Yahoo. I could see at the bottom bar Thunderbird indicating that is was downloading 1 of XX emails, but never actually downloads them. There is no error message. I checked the Yahoo email account to verify the number of emails I am missing from Thunderbird and the number is correct. I can see the emails in Yahoo. I'm the only person using Thunderbird, so no changes have been made to previous settings for retrieval. I confirmed Security and server settings for Thunderbird in and out going emails, and Yahoo are correct. I tested the connection in Thunderbird, and the connection is successful. I tried to send an email from the Thunderbird account having issues, and the email was sent and received by the recipient. The recipient replied, and Yahoo received the email, but failed to download it to Thunderbird...along with all the other emails since 5/25/26. I unlinked the account and reestablished the link between Yahoo and Thunderbird, and still not fixed. I tried restarting the computer, with no change. I tried to send an email from Thunderbird to one of the other Thunderbird emails and it was sent and received. I made changes to Thunderbird to force the download of emails, and it still wouldn't do it. I turned off my antivirus, closed Thunderbird, and restarted it, and that didn't change anything. The capacity of emails on the email in question only has 739 emails, so it's not over the limit and I have plenty of storage capacity. Thunderbird is set to save emails, Cookies and cache were cleared, no change. I ran the folder repair feature in Thunderbird, but there was no change. I compared all the settings between the other Thunderbird emails that are working against the one that isn't, and they are all the same. There was a suggestion to close out of Thunderbird and delete the "Global-message-db.sqite" file from the Thunderbird profile in case it was corrupted, and it would recreate this file when Thunderbird was restarted. The file was recreated, but it didn't fix the problem. There was mention that a suspicious email in Yahoo might be blocked by Thunderbird, so I placed various emails in the spam folder, and it didn't work. I did find one email in the Yahoo spam folder that was dated before 5/25/26 and moved it to the Yahoo inbox. Lo and behold, that one email downloaded to Thunderbird. So there is something within Thunderbird preventing emails from downloading after 5/25/26. I've read many people complain about similar download failures with no solid fix. Someone mentioned it fixed itself on a day, but then stopped again days later. Someone else mentioned Yahoo changed its password protocol to transfer emails, but that doesn't make sense since the other two are still downloading based on the "old" password protocol. I'm at wits' end. Thanks for reading all of this. I hope someone has a solution.

When replying to an email or sending a new mail I get the message :- An error occurred while sending mail. Server responded : You need to authenticate when sending mail from (ip address) Please check "message Recipient" and try again. How do I authenticate ? Thanks140.7.1

I've been using TB for years and all has been working well. But now I have no idea what is going on.

When I try to download new email from my Yahoo account (using pop3) it tells me that it is downloading 1 or 25 (say) and none get downloaded.

Then I delete some emails in TB and a little while later those deleted emails get downloaded again but none of the latest emails. Even if I logiin to Yahoo and delete those emails, TB seems to manage to download them again. How?

If I delete the first email it should download sometimes the rest will download but not always. Sometimes when I update to the latest version of TB emails start downloading.

I have tried to doing a repair on the Inbox but this seems to make no difference.

I've no idea what to try. Anyone got any advice/suggestions?

Also, how do I get from the Beta version of TB to the stable version? I don't even remember choosing to use the Beta versions.

Lastly, I often get pop-up messages saying that folders cannot be compacted because something is using those folders. I've never understood why TB puts out this message. Why does it not just compact the folders when it has done whatever it is doing? Is there a way of stopping these messages and finding out what is using the folders?

Hello everyone! I also had the error, it randomly started moving messages to folders. I deleted everything, reinstalled (155.0.1), started building message filters. I'm at 29 now. (Gmail account) now I'm not getting new messages. For every filter I get a message saying that the filter could not be applied. No messages are coming, anywhere. What's going on?

Thunderbird has been working well, but all of a sudden it stopped sending my emails from aol accounts. I have tried many internet solutions and nothing is working.

Aloha. I'm helping a friend with setting up a new Windows 11 PC, and cannot get Thunderbird to connect to Spectrum's servers. I spent an hour on the phone with Spectrum support and they just gave up and said it must be an issue with Thunderbird. Here are the details:

- Brand new Dell 24 All-in-One EC24250 - Windows 11 25H2 plus all additional fixes. - All Dell drivers updated. - Thunderbird V155.0 64-bit

If I click on 'Get Messages' after a while I get: "Connection to server mail.twc.com timed out". I've gone into the config editor and changed mailnews.tcptimeout from 100 to 500 and still get the error.

In the Account Settings | Server Settings | Test server connection I get: An error occurred connecting to mail.twc.com:993.

I've tried this with both setting up a brand new account in Thunderbird, and also via copying the 'Thunderbird' folder from %appdata%\roaming from her old machine.

Email configuration (from Spectrum).

IMAP Settings Server name: mail.twc.com Port: 993 user name: abcd@hawaii.rr.com Connection Security: SSL/TLS Authentication method: Normal password

SMTP settings Server Name: mail.twc.com Port 587 Connection Security: STARTTLS Authentication method: Normal password

Can anyone help me troubleshoot this scenario?

For the last two or three weeks I have had problems with Thunderbird not downloading e mail from Charter for a few days and then it does for another few days, then it doesn't. Back and forth until the last two days it just seems dead, doesn't receive or send anything. What do I do?

all emails have suddenly been redirected to a single file in a folder in one of 2 thunderbird emails . The file is selected by message filters . it does not matter the origin nor the subject matter , from, to, etc . everthing just goes there . i have checked the filters on the folder in the message rules and these now appear irrelevant . how , why and can i stop and reverse this?

I cannot send email. I get this same error over and over. I uninstall, and reinstall, the error is still present. Sending of the message failed. An error occurred while sending mail. Outgoing server (SMTP) error. The server responded: Connection refused - [181.215.65.87] blocked by Vade Threat List - ELINK003_101 - https://postmaster-earthlink.vadesecure.com/outbound_error_codes/#_101.

Thunderbird used to work. My POP outbound settings: SMTPAuth.earthlink.net Port 587 Connection Security: STARTTLS Authentication method: Normal Password

I contacted earthlink, they didn't help.

When I send photos from my phone to my imac inbox, same email address, or when a third party sends me a verification code, "get messages" is very slow showing results. Sometimes minutes, so I have to go through several verification attempts. The primary email account is gmail. My ISP is comcast.net. I don't know if this matters, because slow Get Messages is recent. It used to work very well

Thunderbird Email: since Sept 2 Thunderbird update 155, my incoming emails are no longer coming into my inbox with my domain host provider webnames.ca. My other staff members have no problems since the update. The only unique thing I can think of is that with my host provider is that I automatically forward incoming emails to my gmail account. Some other staff automatically forward thunderbird email to another thunderbird email of the same domain name without an issue. I can get incoming emails from my other thunderbird accounts ending in the same domain name. The emails do show up in the forwarded gmail account.

All my new incoming e-mails are ending up in the trash instead the inbox. This happens since about a week. I have to move all e-mails from the trash to the inbox. There are no active filters, so what is the problem? Also the layout has suddenly changed. Please help.
