Thunderbird Community Forum

I can only open my emails by right clicking it and opening in new window. Also keeps asking for password every time I go on Thunderbird. Have tried solutions on the help pages and online for both problems but not much use. Some things on account settings and security are not there to select. Is it correct that if I uninstall Thunderbird and then reinstall it the same problems will be present?

I have searched without luck.

Either every thread I can find is about a slightly different version of the question, or none of the answers have worked.

I use Outlook Express 6. I'd like to move over to Thunderbird.

I have several GB of dbx files that I would like to import/transfer/convert and be able to access in Thunderbird.

I tried to use the import tool in thunderbird, but choosing "Import from Outlook" gives me the error: "There is no email program associated to perform the requested action. Please install an email program or, if one is already installed, create an association in the Default Programs control panel." I don't see how this is relevant. Regardless, I have now selected outlook express as the default email action, but get the same error.

I have also tried the "Import from file" option, but the only options are "backed up profile", "calendars", "address books". It would seem to me that it would be common for people to move from Outlook Express to Thunderbird, so it seems bizarre to me that there isn't an option to import DBX files. I've opened DBX files in notepad before, I know they're just text, importing them should be a no-brainer. Do I have to write my own conversion program?

I have a couple of hundred filters and one of them occasionally kicks in and unexpectedly moves certain messages to a new folder but I can't figure out which filter it is. Rather than me going through every filter manually, can't Thunderbird tell me which filter affected a given message? I'd like to be able to right-click a message and be shown the exact filter(s) which affected it.

15.18.0 how to export to mobile from settings in the desktop thunderbird so i can use my android phone--if it will help, on my desktop there is no Export to mobile in settings!!!!!!!

Will Thunderbird Release make it any easier to migrate Thunderbird from Win10 to Linux (Ubuntu or Mint)... With 200 million PCs becoming obsolete in a few months, I would think Mozilla would have noted that many of us are going to migrate to Linux but moving Thunderbird has been a nightmare (still unsuccessful nightmare). I've followed all the directives and none seem to work... I've been using TBird since it started and have a LOT of emails I'd prefer not to lose so if I could just get my Windows profile to work on Linux it would be great... I know you're busy, but we are facing an Armageddon of sorts out here... Help! Thanks a million cheers pj

Updated from 138.xx to 139.02 today.

Archiving from either of my two feed (RSS) accounts doesn't work right. I click archive button, instead copies to the archive folder of first email account in list.

Used troubleshooting mode to disable addons, still happens. Saw nothing in changelog to explain this.

A bug?

Since 5.18.2025 I get a "no message found" in my sent folders and other folders. "Find" will still find the messages and they can be opened, but I can't get the email folders to display. I know they are still there. Version 128.10.2esr. How can I get them to display in the folders?

Can I use Thunderbird to build an incremental local backup/archive of all messages transiting (incoming/outgoing) a webmail account ?

Any idea how to achieve this ?

My problem is:

• A POP3 account will miss all folders except the Inbox. (It's a pity that POP4 has not gained traction yet.)
• An IMAP account creates a mirror, not a backup. Remote deletions in the webmail account must not delete messages from my backup and vice versa.

detailed requirements:

• one-way sync only, since a local backup/archive must be built, not a mirror (two-way synchronization):
• Remote deletions must not cause local deletions (otherwise it would be a mirror, not an archive/backup).
• Local move/delete operations must not be reflected back to the mail server.
• Read‐only access to the mail server: no moves, deletes or flags remotely.
• All messages in all folders must be included in the backup: Inbox, Sent, custom folders, etc. Since POP3 can only back up the Inbox, I will probably have to settle for IMAP to include all folders.
• No duplicates: Messages must not be stored locally more than once.
• Messages must be stored as full offline copies locally (not just headers).

I am running Thunderbird ESR 128 as a snap on Ubuntu 24.04. I have several different email accounts and until a couple of days ago, when I replied to an email on account 2 or 3 it was sent as from that particular account. Now it is being sent as if from account 1. Trying to send an email as if from account 2 or 3 results in a failed-to- send message. I have noticed that when I look at the from field for accounts nos 2 and three the following is being inserted before the normal email address "NSIMsgidentity: 1d6 (or 1d7). Can anyone please advise me why this is happening and how to recover the ability to reply / send an email from accounts 2 an 3 as if from those accounts rather than from account 1? Thanks in advance

Hi,

When I switch from the Calendar tab to any other tab (Inbox, Address Book, Tasks, etc.) and then return to Calendar, the calendar always jumps back to 12:00 AM in the daily and weekly views. Previously, it would remember the correct time range I was viewing.

For example, if I’m looking at 8:00 AM–6:00 PM time period in the calendar and switch to another tab, returning to Calendar resets the view to start at 12:00 AM. I then have to scroll down every time to get back to my usual working hours.

Please restore the previous behavior where the calendar maintains its last scrolled/viewed time range.

Thanks!

I have about six email accounts on my Thunderbird. One is associated with my internet provider. The rest are related to my website server. All of the accounts. except one, are working fine. The one that isn't working somehow lost its password. Its an account related to my website. For a while I could get incoming mail but I couldn't reply. I changed the password at my web host, and now I can't receive or send.

What do I need to do to restore this mailbox's functionality?

Many thanks for your suggestions

Добрый день. Нужна срочно Ваша помощь. К нам пришло сообщение от почтового сервера mail.ru Что нас заблокируют с 24/06/2025 числа. Мне поддержка написала, чтобы скачать с облака почту на компьютер нужно установить почтовую программу и перечислили их в качестве примера. Я установил на свой комп Thunderbird. Создал локальную папку на компе у себя. И запустил программу, чтобы прогрузились все письма с сервера. Оставил на сутки. Потом выделил в папке входящие все письма и нажал кнопку архивировать в локальную папку. Тоже самое сделал с отправленными. В итоге сейчас на сайте начали пропадать исходящие письма и входящие. Входящие резко пропали за 25 год до 20 Хотя я ничего еще не удалял. Думал прогружу почту всю с 18 года в локальную папку на комп. Скопирую ее Архив еще раз отдельно и удалю только с облака до 21 года, чтобы освободить место в облаке. Но тут происходят чудеса. Помогите пожалуйста. Как все восстановить и сделать правильно. Готов предоставить доступ через Ани деск

A week or two ago I started having two problems with Thunderbird, but only with some emails related to my clients. Here is a description of each problem (in case the problems are related):

Doubled incoming emails

Emails received at my address david@nsrusa.org are being received and displayed twice. I have set both my email domain servers to delete messages from the server, which is the top advice always given for this problem. The advice doesn't work for me.

Outgoing message failure

Some messages I send using Reply (perhaps the doubled messages) are getting "stuck" in my email server, which keeps sending me updates on this failure. Here is the start of a typical failure message:

This message was created automatically by mail delivery software. A message that you sent has not yet been delivered to one or more of its recipients after more than 48 hours on the queue on server.springtimesoftware.com.

The message identifier is: 1uQFjK-00GA1j-05 The date of the message is: Fri, 13 Jun 2025 21:30:45 -0400 The subject of the message is: Re: Your recent postings

The addresses to which the message has not yet been delivered are:

 ***@bol.com.br
   host mx3.bol.com.br [200.147.41.201]
   Delay reason: SMTP error from remote mail server after RCPT TO:<***@bol.com.br>:
   450 4.7.25 Client host rejected: cannot find your hostname, [69.48.183.241]
 ***@gereconsult.com
   Delay reason: H=mx-vip-01.kinghost.net [191.6.216.38]:
   SMTP error from remote mail server after RCPT TO:<silviomartins@gereconsult.com>:
   450 4.7.25 Client host reje

My environment: Mailservers are mail.nsrusa.org and mail.springtimesoftware.com, both at IP address 69.48.183.241, Windows 11 Home 64, Thunderbird 128.8.1esr 32 (I have just updated to 128.11.1esr), hp laptop.

I have a rule that moves email messages from backups to a 'Backup' folder. I also have another rule that moves emails address to myself to 'My Mail'.

When I start TB 128.11.1esr in the morning my 'Backup' and 'My Mail' folders show new email counts. When I click on 'My Mail' the number on it decreases and 'Backup' increases. This happens with other rules on other folders.

So, my question is this behavior caused my 'Message Filters' being triggered when I click a folder or potentially a latent refresh of the folders new email counts.

Thanks

Hello Team, I installed thunderbird yesterday and so far its looking promising and actually I started to like it. But when on my first email draft I tried to use search and replace (Ctrl + h), I was not getting any highlighted letter on pressing 'Find Next'. When I press on 'Replace' still 'Find Next' button is highlighted and also nothing seems to be replaced. It is only when I close the Find and Replace window I see my changes. I am attaching picture for your reference. If this is not standard feature then please provide support to fix this issue.

Just installed the latest 139 version on two computers, the system tray icon for unread messages appears in Windows 10, but not in Windows 11, and it isn't just 'hidden' as I have many icons hidden and just a few visible and have already checked that. Is the icon no longer part of the program?

how can I copy my encrypted gmail passwords so that I can use it to sign into my Thunderbird gmail accounts to send and receive email using the Thunderbird app? Thunderbird has now decided that the passwords I have used for years to sign into my two gmail accounts are not valid. Think Tbird wants the encrypted version of each password, but don't know how to figure out what that is. Not listed in the encrypted version in my Tbird saved passwords.My other accounts continue to work well with Thunderbird. I havve many folders that I do NOT want to lose i I have to delete and then reestablish those two accounts, but the copy/move to another folder on my laptop will not work. Nothing happens when I try to follow the instructions. Please help!!
