Thunderbird ერთობის განხილვა

The authentication is not working with many of the directions I have found online. I create an app password from logging into AOL website and have no where to put the password. If the password request is made is does not accept the password. Things aren't where the direction indicate. Getting the connection to request the password sometimes works but no password works. I tried the app password and rejected and multiple other password don't work.

Based on the latest version of Thunderbird where things seem to be changed, how to specifically set up this new authentication.

It's driving me crazy,

Thanks...Carl

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

After a long explanation, I tried to add a file and lost everything. Starting over! After using TB for over 30 years, I accumulated a large number of personal folders to archive files to. Due to confusion on my part about pass words in Proton Mail and their Bridge, I had to reinstall my ProtonMail account into Thunderbird. Because all my personal folders were connected with the old "account" name, I didn't remove it, and the new addition seemed to be working fine.

After doing some house cleaning to remove duplicate and obsolete files, I wanted to move the folders attached to the old account name, under the new name. I thought I could carefully move my personal folders from the old account, back under the new Protonmail account. Sadly, that doesn't work like that. What I did find was that the original folders which come under the original "account", were created with an older version of TB, which put them in a folder on my HD. But the new default folders ("inbox", "draft", "sent" etc.) are mirrors of the Protonmail Bridge, which is NOT what I want.

So I need someone that knows how to either place the old folders back under the NEW "account", or how to create new folders that ARE on the HD, and then move the files from one place to the other.

Just to help clarify, here's the location of the old folders as per the "properties" info.

mailbox:///E:/thunderbird data/thunderbird/yetudx3p.default/Mail/Local Folders/Friends & family

You can see the address for this folder is on my Drive E: I can go directly to that address on my drive E and see each of the files.

imap://gshantz%40protonmail.com@127.0.0.1/Folders/2009

This folder is from the NEW account of Protonmail - bridge, and is obviously the web address of Protonmail. It is NOT editable, unlike the above location on my HD E:.

Any help or suggestion would be greatly appreciated, gshantz

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?

Just started Thunderbird and all my accounts and mails are gone. All empty. I tried to import from default: C:\Users\Korisnik\AppData\Roaming\Thunderbird\Profiles\fjv3tdcd.default and now I have mails until 2025, all from year 2026 is gone. What to do???? please answer to [redacted email from community support forum]

In TB 155.01 when I click on Delete the email leaves my Inbox but does not display in the Deleted folder. If I look at Properties in the Deleted folder it shows the correct number of messages in there but the messages themselves do not show in the right hand window. Thus there is no way of seeing what the messages are, just the total quantity in the folder.

This morning, my email Inbox is empty. I use Thunderbird for four email accounts, and three of them are fine, but the fourth one has an empty Inbox this morning. I didn't (intentionally, anyway) move the emails anywhere, and they do appear to be in the All Mail folder, so I didn't lose them entirely. But I keep my emails mostly in my Inbox and they aren't there anymore.

Any ideas what happened to make them disappear and how I can get them back to the Inbox?

Thanks!

Здравствуйте! 1. Почтовый клиент стал показывать в папке "Входящие" по 10-15-20 копий одного и того же сообщения. 2. Когда-то была создана папка "Pending"во входящих сообщениях. Сейчас почтовый клиент сам по себе поместил ее в папку "Удаленные", причем во входящих двух разных почтовых ящиков. Создать эту папку как отдельную во входящих не удается. 3. Удаленную папку "Охрана труда" почтовая программа также поместила как отдельную папку в удаленных и воссоздает ее снова при запуске почтового клиента.

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

Having established a new Outlook account I cannot sign into it properly with Thunderbird - I get authentication failures each time despite all settings apparently being correct, IMAP enabled in the web browser view of the outlook account and so on. Oauth2 set and all server settings good. I have been over and over things. Tried various suggestions of the web to no avail.

I have tried unsuccessfully with three separate machines - two Microsoft 11 laptops and an iMac. All fail.

I can access the account and send/receive emails from a web browser and I have got it working okay with an iPhone, an Android tablet and a Microsoft email client - but not with Thunderbird. I even get a browser popup on the iMac when I open Thunderbird asking if I am trying to sign in - I say yes and it says I am all signed in - but the email doesn't authenticate. I have passcodes all set up etc.

A separate Hotmail account does work with the same Thunderbird client and has the same server settings (apart from the username obviously).

I am at a loss how to resolve this other than move to a different email application.

Any ideas?

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?

I have Thunderbird 153.2.0esr which runs 2 Email filter (on Inbox and on Outbox)

These filters worked for years.

Suddenly, about at the end of July 2026, the stopped working.

I suspect that one of the latest release of Thunderbird make them stop working.

Is it possible? Any suggest?

Also the filter log registry is empty.

Environment:

• macOS, Apple Silicon (aarch64)
• Thunderbird: 155.0.1 (aarch64), Release channel
• Email hosting provider: Hostinger
• SMTP server: smtp.hostinger.com
• SMTP configuration: Port 465, SSL/TLS, Normal Password authentication

Problem: Incoming email via IMAP works normally, but Thunderbird cannot send any outgoing email.

The error is either:

“The connection to Outgoing server (SMTP) smtp.hostinger.com timed out.”

or:

“Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.hostinger.com failed. The server may be unavailable or is refusing SMTP connections.”

Troubleshooting already performed:

• Webmail can send emails normally.
• Thunderbird can receive emails normally.
• SMTP settings and username have been verified.
• Port 465 with SSL/TLS does not work in Thunderbird.
• Port 587 with STARTTLS was also tested and does not work.
• Tested with a different network/mobile hotspot — same issue.
• Tested Thunderbird Troubleshoot Mode — same issue.
• Updated Thunderbird from 155.0 to 155.0.1 — issue persists.
• Direct TCP connectivity from the same Mac was tested successfully:

nc -vz smtp.hostinger.com 465 → succeeded

nc -vz smtp.hostinger.com 587 → succeeded

Therefore, the SMTP server is reachable from the Mac on both ports, and the same mailbox can send normally through Hostinger Webmail, but Thunderbird fails to establish/use the SMTP connection.

Since sending was working normally before the Thunderbird update and stopped afterwards without any SMTP configuration changes, this appears potentially related to the recent Thunderbird update.

Could you please advise whether there are any known SMTP/TLS/socket issues with Thunderbird 155.x on macOS, or any additional diagnostics/settings I should check?

Years ago when I was using Thunderbird there was "fix" for the Advance to next message pop-up, which appears when you press N or P to move to the next/previous message, and that message is on another account. If I remember correctly I think the fix was going into the "debug list" where you could change individual settings if you knew the name of the setting, and set it to off.

Anyway I couldn't find that list at all in the current version (probably a good thing). Is there a setting somewhere or fix where I can turn off this popup?

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.

I updated to 155.0.1 via the update modal yesterday, on MacOS Tahoe, and it didn't restart as normal. The main message pane was blank with "No Message Found" (screenshot attached).

I tried installing a fresh 155.0 over, that did not work; but, a restore of the prior app from my Time Machine did work -- that is, the application not the user profile data.

I just thought this was strange; never ran into it.

If there is an issue and I can help test it usefully, I happy to do so (I have backups! LOL).

On September 5, Thunderbird updated to 155.0 (20260828141248) (on Windows 11 10.0.26200). I use IMAP.

Since then, when I try to delete a message, I get an error: The current operation on ‘Inbox’ did not succeed. The mail server for account <email address> responded [TRYCREATE] Mailbox doesn’t exist: INBOX/Trash (0.001 + 0.000 secs)

But in Settings, "When I delete a message: Move it to this folder: Trash" is set. Not Inbox/Trash or INBOX.Trash, which also exist, but Trash at the same level as Inbox. I logged into webmail for this account, and there's definitely a folder for Trash. All deleted messages prior to the update are still there. If I delete a message in web mail, it is moved to the Trash folder.

The same is true of the Sent folder. In Settings, "When sending messages, automatically: Place a copy in: "Sent" Folder on: <account name>."

It looks to me like Thunderbird is doing something different from what the Settings say, and definitely something different than what it did before the update.

Suggestions?

I'm aware (e.g. https://support.mozilla.org/questions/1277401) of how to toggle whether the message window stays open (opening the next message) when an email is moved or deleted. But I would dearly love for it to happen only sometimes.

Specifically, when a new message comes in, I want to read it, usually move or delete it, then read the next new message, if there is one. But if the next message is an old one, I don't want to keep having it shown to me. I keep my inbox fairly tidy, but I'm getting sick of seeing that message from a year ago that doesn't have a better place to be.

So, after moving or deleting a message, if there is an adjacent unread message, keep the window open. Otherwise, close it.

If there's an unread message somewhere else in the folder, don't jump to that one. Trust that I've left it unread for a good reason, and don't want to now constantly get shown it, and also have to remember to mark is as unread again.

If it's easier to look for other unread emails based on dates, a few days (enough to span a long weekend, for example) would probably be enough, a week at the most. Or make that number user-configurable.

Recently I posted about this problem here: https://support.mozilla.org/en-US/questions/1580858 In sum, I was having problems both in downloading messages from the Spectrum server and also with sending messages. I've attached screenshots of the error messages.

Matt and David kindly posted some helpful responses. The problem then seemed to spontaneously solve itself and I breathed a sigh of relief. Then a few days later it re-appeared.

This time it's not quite as bad in that I'll get the error messages but then usually a few minutes later I can download the messages or send an email. But it's still a real problem.

I called Spectrum again and this time the rep was adamant that if I can still use the Spectrum webmail feature (and I can), then it's not a Spectrum issue.

Last time Matt asked about my antivirus. I use Windows Defender (and occasionally do a manual scan with Malwarebytes free version), so if I understood him right, I should be OK as far as antivirus interference.

Matt also suggested I set TB so that I download messages at startup and every 15 minutes. I was set to every 10 minutes so I changed it to 15.

Matt said for me to check the Activity Manager. I've attached a screenshot of what that showed a few minutes ago. But I should note that this was after an error message displayed but my email downloaded anyway.

Finally, Matt said I should check the Error Console (Control + Shift +J). I've attached a screenshot of that. He also said I should use the trash can to clear it, so I did. He then said to press Shift + F5 to attempt to get my messages. But on my laptop, F5 just dims the display so no dice on that. But I have a second laptop and F5 is "neutral" on that one so I tried it there. I didn't get any new error message.

However, one of the screwy things is that sometimes I get all my messages as normal, but only after the "Can't connect to the server" message displays. And that's what happened with my second laptop above.

I hope I've provided better info. this time. And I hope you gents can help me with this mess.

Thanks,

Andrew
