Thunderbird Support Forum

As of Sunday, Thunderbird can no longer reach my ATT server to download email. It has behaved for ten to fifteen years. Last time someone at ATT fixed it. I have been on the phone or on screen with ATT most of my waking hours since Sunday. (In the process I lost my internet, my landline, my cell connection, etc.) Everything is restored except the connection between Thunderbird and ATT. Everyone thinks changing my password will do it. Done it four times. It gets me into the ATT mail. I have replaced the password in Thunderbird settings with it to no avail. Is there anything you can think of? Not only is Thunderbird more attractive than ATT, I have thirty years of mail boxes there, a continuation from Eudora. I will appreciate your wisdom.

I hope someone can help, I've changed all the settings in Thunderbird for my whole family's emails (hotmail.co.uk, hotmail.com, live.co.uk) from Normal Password to OAuth2. All incoming and outgoing servers are exactly the same as Microsoft advised. None of my accounts work, neither for sending or receiving.

I removed one account and tried to re-add it (that was the advice given if the first method didn't work) but when it tries to check the password, it takes forever. I've tried to manually configure it but it wouldn't download any folders or emails. I removed it and tried to re-add it but have been unable to do even that.

My default account hasn't been able to send more than 25% of emails for a few weeks. I'm up to date with all updates and I've restarted Thunderbird and my laptop countless times.

Can anyone point me in the right direction please?

Outlook.com and Microsoft inform me that in September 2024, Outlook 2007 will no longer work for email because it does not meet their spiffy new authentication thingy. They want me to quit using Windows 7, but I need it to run legacy productivity software for which there is nothing comparable. So, Windows 7 it is. I do have a dual boot system that includes Windows 10, but I don't want to mess with it for email if possible.

Microsoft suggested that Thunderbird would work, so I downloaded it. That's when everything went sideways. There is no utility to move my existing files and folders intact from Outlook 2007 to Thunderbird. I tried Thunderbird's Import but it refuses to cooperate. So, last chance for Thunderbird is contacting you.

Help me make a clean transition from Outlook 2007 to Thunderbird without losing contacts, folders and files.

System specs below. Thunderbird is set with 1 account: A paid Yahoo email, with a LOT of messages (well over 36K), using IMAP (Yahoo only lets the most recent 10K come down via IMAP, sadly). Most emails do download and are correctly rendered. But around 10%, starting usually a month or so back from the high water mark of last update, show email source code (text of headers, mimeparts, etc.) for a totally different email than the one highlighted (a few days later, different sender, etc.) Checking the message on Yahoo, it renders correctly. There is no pattern to the corrupted messages: they can be from mailing lists, company marketing mails, an alert from my local town, whatever.

Once the error occurs, it is consistent across Thunderbird shut-and-restarts (still showing same wrong email source as before). Emails to either side (earlier and later) render properly in the message pane.

Double Clicking the message to it's own child pane renders a pane with Subject and From as blank, and the same email source text for a different email. Forwarding the email puts the email source code in as text (I was hoping the act of refreshing and reformatting might grab the correct content, but no).

Doing a Repair Mailbox (which seems to mean "download headers again, then download all the mail again" does seem to correct for a time (including the previously corrupted emails now rendering correctly)... but within a day or two, a new crop of messages will be corrupted, and the dance starts again.

Windows 10, 64 bit. Norton 360 set to exclude all mailbox directories. Thunderbird 115.12.2 (64-bit), though this has been happening since 110. No plugins, no extensions.

Are there diagnostic logs or other info I can share that can help us figure this out? I really like Thunderbird, but it's just unusable here. Outlook, Apple mail, other tools don't seem to have this problem.

Hello --

Not sure when this happened.

Got 2 email accounts, account X and account Y. All was working fine until today, 6/27/24. Both have different outgoing SMTP servers.

Now I am trying to send, it is asking for passwords, which I have and is 100% correct. In fact, if I put in wrong password it tells me, so I know it is communicating. When I put in the correct password, I get a timeout on BOTH SMTP servers.

I disabled Norton Firewall.

Works fine from another PC app (poppeeper) and from my android (k9 mail). Both accounts are IMAP.

Neither SSL/TLS or STARTTLS makes a difference. Nor did a re-boot.

TB 115.12.2 (64 Bit) on Windows 10

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mailroom4.hostrocket.com timed out. Try again.

Description: hostrocket Server Name: mailroom4.hostrocket.com Port: 465 User Name: ernie@e(redacted).com Authentication method: Normal password Connection Security: SSL/TLS

Anything change?

Tell me how I can continue to use thunderbird with the above account and also Denis.Clarke.hotmail.com after September 18. I have 4 individual historic E mail accounts and thunderbird joins them together. What do you need to do? To deal with threat below.

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Hi, I've just had an email from Microsoft saying :-

Update your sign-in technology before September 16th, 2024 to maintain email access.

Is there a step by step tutorial on how to do this?

Regards,

Paul

I converted my Outlook .pst file to an mbox file using SysTools PST converter When I try to import it into Thunderbird, it permits me to import only a .zip file from a previous backup, or a calendar file, or an address file. I need it to import the whole thing, especially the emails. How?

Hallo, durch eine Unachtsamkeit habe ich das Hauptpasswort (Primäres Passwort.) von Thunderbird gelöscht. Ich finde auf den Hilfeseiten keinen Hinweis wie man da Passwort zurücksetzten kann. Dadurch komme ich nicht mehr an meine Mails. Freundliche Grüße

A new problem since July 1, 2024 Thunderbird keeps crashing on start-up when checking for new mail. HELP!! Crash ID: bp-e8be7291-7fe9-41c0-bd21-45d860240702

have been using Thunderbird mail for about 3 years. It’s template selected the incoming and outgoing servers and ports etc..successfully. I've been connecting to Prodigy mail/ATT I had to change the battery and it doesn't work anymore. Can you help ???it checks the password until it shows an error message that the servers password or etc are wrong. I know the password is right since I can log in directly. Messages :

1- Configuration found in ISP Database

2- Checking Password (for a few minutes

3- Unable to log in at server..probably wrong configuration username or password

4 then nothing

Worked great before battery change

I received a notification from @hotmail and @live that I won't be able to receive or send mail after Sept 17th without taking action - what steps should I take when I don't have Microsoft Office 360?

We have recently moved to a new mail server. We currently have about 20 Thunderbird email clients on Windows in an office location and a macOS home machine. On all machines email is configured to use IMAP on hostname.com port 993 SSL/TLS with Normal Password and SMTP on hostname.com port 465 SSL/TLS with Normal Password.

The home machine is working 100% with no issues, it does have a much faster and lower latency internet connection than the office machines.

Many of the office machines are experiencing intermitent SMTP error messages when sending, intermitent, "unable to save mail in the Sent folder of the Inbox", messages and intermitent unable to move messages between folders.

I have checked and double checked the settings on affected machines - however, I believe a settings issue would result in nothing working, not intermitent functionality. Plus all is working fine on the home machine with the same settings (different OS, but ports and security settings all dictated by server).

With one client behaving properly, the server likwise behaving properly when addressed by the working client and the intermitent nature of the problems we are finding, I suspect we have some sort of network issue. Somthing timing out or a firewall/AV software causing a delay.

I have increased mailnews.tcptimeout on affected machines to 250 based on a forum article but this has had no effect (No idea of units here but if it is seconde then I am not supprised - the SMTP errors, when they happen are almost instantanious).

Any ideas on how to trobleshoot this problem further - The problem seems to get worse through the day, although that may just be peoples tollerance of an intermitent issue going down.

I set up a new Windows 11 PC (64-bit) about 2 months ago, and installed Thunderbird Supernova. I allowed MTS to choose all the settings and everything was working fine until about 3 weeks ago I am now running version 115.11.1 (64-bit). I noticed that many messages I recieve at scheduled times every day were not appearing in my MTS message list until sevveral hours (a few actually took 3 days) after their normal delivery times. Checking with the senders revealed no change to the time they were sent. Looking at the messages when they appeared showed that they WERE received on time. Logging into the web interfaces for Gmail and Comcast/XFINITY email revealed that the messages were arriving on time. The only logical conclusion is that MTS has a problem in its IMAP protocol implementation that does not recognize new/unread messages as such, and therefore does not retrieve them. I am legally blind, and up to this point, mTS is the only fully accessible, easy-to-keyboard-navigate email program.

WHY is it that I can get into my email account through Thunderbird and download mail, but when I try to go into the account manually I can't? I go into the settings copy the password, then manually input it into gmail, but it says it's the wrong password? I am using MacOS 10.14.6, and Thunderbird 115.12.2 (64-bit)

Thanks.

I have TB ver 115.12.2 64 bit. It reports as being up to date. During attempting to make the changes necessary to accommodate Microsoft's Modern Authentication I reach a point where the option to select OAuth2 does not appear in the Outgoing Server SMPT settings drop down menu, see the image. How do I deal with this? Thanks for your help.

I was looking for an email I expected to find in my Inbox, and found that a message filter was applied to move it to another folder. I can see the filter log entry for this action.

This filter consists of 9 specific email matches ( From "is" ....); the message that was moved is NOT in this filter list.

When I moved the message back to my Inbox, it was moved again.

Any ideas on how to stop this happening? Can I even trust filters?

I recently deleted all my filters as I was not sure they were working correctly, and recreated them carefully. I currently have 10 filters, a few are one off created from a message, and none have more than 10 matching requirements.

I have attached an image of the filter at issue, and here is the filter log entry:

[7/1/2024, 9:40:07 AM] Applied filter "Bad Shopping" to message from grandrr@olypen.com - [RW] RW Potluck Tuesday July 2 at 7/1/2024, 9:19:44 AM moved message id = faecf27e13e90b655df9ff49ee14a5ec@olypen.com to imap://sjstowell1000%40gmail.com@imap.gmail.com/Good Causes & Bad Shopping

Why? Actual bug? DB problem?

I have done a custom install of TB on D:\ drive, moved Profiles folder to D:\, verified that account settings/server settings have local directory pointing to D:\ drive.

Can I delete all TB files on C:\? TB still *seems* to be using those files. I really need to free up space on C:\ - tiny drive filled with Windows OS, huge D:\ with nothing on it.

Thank you for your time and attention!
