Thunderbird Community Forum

I have several email accounts in Thunderbird where the email address no longer exists, at least on the specified IMAP server. Thunderbird is configured to not attempt automatically getting mail for these.

I had used Thunderbird 102 on Windows 10 for years, and in that version, my mail was kept in Thunderbird for those accounts (though whenever I opened any folder in them, I was somewhat annoyingly prompted to enter my credentials since the connection to the server was failing). To copy my profile folder to a new Linux installation, I updated Thunderbird to 153.5.1esr, the same version running on Linux, as Flatpak. My mail is still kept in Thunderbird on Windows, but with the same profile on Linux, Thunderbird "hid" all folders from the offline email accounts (apart from an "Inbox" folder that is shown as empty): the files are still there in the profile directory, and Thunderbird seems to find relevant emails in search, but opening them leads to a "No mail found" screen, and there is no way to access this mail from the folder pane. How can I make Thunderbird see my mail again?

As if that was not enough, on a whim I decided to attempt the "Repair folder" option on my Windows instance of Thunderbird, where the folders were still being shown normally. I immediately regretted not having made a backup of my profile (I only have one from version 102, where the data was apparently stored rather differently), since this just deleted all mail in the selected folder entirely, with the relevant file in the profile directory being empty. (The file seems to be somewhat different on Linux too, since copying it back to the Windows profile did not restore the mail in Thunderbird, and I would probably have to copy my Thunderbird 102 backup into an install of Thunderbird 102 and manually upgrade to my/the newest version to get it back.)

I know local folders would never be deleted like this, but there does not even seem to be an option to move an entire mailbox into a local folder, other than manually. It does not appear like Thunderbird has proper support for mailboxes that are no longer available. It would be undesirable to have all my mail in some new mailbox lost in the same way after I lose access to it. (Local folders would not really help in this situation either, unless you plan out exactly when your mailbox goes offline.)

Attachment Hello, For the past few days, when composing a new message, it has no longer been possible to attach a file by clicking on "attachment." The only way to add an attachment now is by using drag-and-drop. Is this a bug, or is there a setting that needs to be configured? Thank you for your response. Best regards,

Prior to the update to TB 153.5.1esr (on Linux Debian) all was fine. The update was accompanied by (caused?) a display that is huge, such that much of my content is off-screen.

Problem downloading emails from Yahoo

For years there has been no problem, but about 2 weeks ago downloads stopped. Pane at bottom of Thunderbird says downloading message 1 of 292, but is is stuck at 1 and nothing downloads.

Today something different is happening, it downloads the first 80 messages then returns again and downloads same messages again, then repeats. I now have 17 duplicates of these same 80 emails just in the time to write this and it is still downloading the same 80 over and over again.

I have searched internet for solutions. I have done the following:

Updated to Oauth2 through Yahoo website. Thunderbird shows a saved login password oauth://login.yahoo.com, plus my correct email address, plus an OAuth2 password

Checked all server settings. All correct, e.g, pop.mail.yahoo.com Port 995 SSL/TLS security, and OAuth2 authentication method

From server settings page I tested connection to server which came back successfully

Same as above for outgoing server.

I have ample disk space on my computer and ample data capability on Yahoo account.

Confirmed not in offline mode. Confirmed cookies and javascript enabled.

BTW, I can access all my mail on Yahoo’s web page, but that is inconvenient. I really prefer access through Thunderbird.

I have deleted global-messages-db.sqlite and Thunderbird reestablished it. Did the same for popstate.dat, and inbox.msf

I even uninstalled Thunderbird and reinstalled it but no improvement in the problem.

I am out of options now. What to do? Thanks so much.

Hello Good day,

With thunderbird I have tidied up my e-mails at server at googlemail.com yesterday ?!

I have deleted 50 percent of "all-inbox" and of "sent messages".

This means that - before this - 12,9 GB of memory at googlemail.com were used. Now it should be at about 6 GB of memory used actually ?!

In thunderbird-window below it is said that 12.9 GB of memory are still used ?!

Normally it should be at 6 GB of memory are now used ?

Thunderbird says still "storage is 85 percent full" ?!

Have I to wait some days until memory usage is actualized ?

Thank you for answer. Greetz. dschinn1001

A few times I have missed messages that have have been inadvertently placed in the Accounts Spam Folder. Is it possible to to indicate that the Spam Folder has contents in the same way contents are indicated in other Account Folders?

The option "Edit as New Message" is only available when a user right-clicks on the body of an email.

The option is not available in the menu displayed from the "More" button on an email. The option is also not available in the right-click menu on an email in a mailbox list. The option is only available in the right-click menu from the body of an email.

Requiring a user to use the right-click option in a specific area of the user interface is an accessibility issue which should be fixed.

When I attempt to write or forward an email, the send option is grayed out and I can not send. But I can reply to an email and the send icon is active. Could this have something to do with the fact that I have had a substantial number of emails and I have used thunderbird for many years causing a pointer to flip? If so is there a way to fix this?

Details: Write/forward email send disabled, reply email works fine. Thunderbird for Linux Mint mint-001 - 1.0 153.4.0esr (64-bit). Linux Mint 22.1

I keep getting an error message that says to look in the "Server Logs".

Unfortunately, I am unable to catch the error message.

Could someone please let me know how to see the server logs?? Thanks Martin

After upgrade to thunderbird 153.5.1esr from 140.17.0esr on a debian 13 (trixie) system I can no longer digitally sign my message with my external OpenPGP key located on a smartcard: I get the error message "Unable to send the message, because there is a problem with your personal key. The configured key ID ‘...’ cannot be found on your keyring." If I try to import the public key via the OpenPGP Key Manager I will get the alert "Importing the keys failed. TypeError: RNPLib.prepare_ffi is not a function". Any idea how to fix this?

Example why question is being asked:

Three separate GMX email accounts, each with its own unique password, and NOW Application-specific password for Thunderbird. Aliases are not used or desired. Three different separate accounts that should each have its own outgoing server.

Worked fine until updates to Thunderbird and changes to the GMX server, and Application-specific passwords became a requirement to send and receive email.

Seems like updates to nearly every program and/or app that may be released with the intent to resolve an issue or include a new feature breaks something else. M$ is horrible with updates and labels nearly everything as a critical update so it gets pushed through even when updates are turned off or supposedly permanently disabled by a registry hack; Windows 11 being the absolute worse ever. Why I only have one computer with M$ while all the others are Linux. Problems all the time with M$ while Linux simply continues to work.

Regardless, can setup each GMX account but the default email account name must be used as the user name on the other two GMX accounts on the outgoing server in order to send email. Then the recipient sees the name for the default account rather than the name assigned to the other two accounts, and the Application-specific password for Thunderbird must be changed to that of the default. Then attempting to pull down email for the other two pop accounts comes to a halt, and email messages can only be viewed by going to the online account.

Two separate accounts for yahoo, two for gmail, and one for Charter work fine, each has its own name and outgoing server. Should be the same way for GMX but is not because Thunderbird requires one of the three GMX accounts is set to Default.

Appears by having a Default email account, users are not only restricted by the default account, but email that is sent is done so with he incorrect name, The purpose for three different emails is for email segregation and better management; personal correspondence, business related, and Internet stuff.

Instead of having a 'Default' email account, makes more sense to use a valid email to register Thunderbird after downloading and installing, and then using that email for Support, Boards, assistance, etc. The default email requirement causes too many frustrating unneeded issues that should not occur, along with wasted time, stress and grief. Computers were suppose to make our lives easier and allow us more time for the real world. Biggest lie told since the Bell Labs created the transistor.

Hello,

Since I updated Thunderbird to the version 153.5.1esr (64 bits) on Debian, I can't access to my PGP keys anymore, so I can't encrypt/decrypt my mails with OpenPGP.

In the console, I found this error message when starting Thunderbird: Error: RNP/OpenPGP library failed to load

And in OpenPGP, when I try to import keys (in .asc format), I've got this error message TypeError: RNPLib.prepare_ffi is not a function

I'm lost and I couldn't find any relevant information about this error for this version.

What can I do ?

Hello New to TB, it's working well. My question is that I can't find a setting that causes emails to be downloaded immediately from the server as soon as they are received. Is there one?

The only available settings I can find are

Check for new messages at startup Check for new messages every (minimum 1 minute) Allow immediate server notifications when new messages arrive

If I have all of these checked then I should get an immediate sound and/or visual notification when a new message arrives on the server and I can see its header, so what is the significance of the "check for new messages every (set to 1 minute)" setting? Does that mean it will download all messages, including bodies, received in the last minute without any user input?

Bonjour,

Depuis plusieurs semaines, je ne peux plus du tout joindre de pièce à mes mails.

Pourriez-vous m'aider à résoudre ce problème, svp ?

je vous en remercie par avance.

Bien cordialement

Subject: Thunderbird fails to send multiple PDF attachments – Server timed out

I am using Thunderbird on Linux Mint 21.3.

Thunderbird sends ordinary emails without problems. However, when I attach two specific PDF files received by email from my bank, sending fails with the error message “Server timed out”. The message cannot even be saved as a draft.

The files are very small (148 kB and 54 kB).

I have established the following:

Each PDF can be sent individually from Thunderbird after renaming it.

Sending the two PDFs together fails, even after renaming them.

Forwarding the original email containing the attachments also fails.

Sending the same attachments together via GMX Webmail works immediately.

Other emails sent through Thunderbird work normally.

This appears to be a Thunderbird-specific problem involving multiple attachments or the processing of the original email, rather than file size or a general mail-server outage.

Could you advise how to diagnose this issue and identify the cause?

System: Linux Mint 21.3 (Virginia), 64-bit.

I type enter and there is an extra blank line

Like this

I can't seem to find a way to stop it.

It doesn't affect bullet lists:

• Bulleted list item
• Bulleted list item

But I can't provide a tidy chunk of information, e.g. when providing my Address to someone (where bulleting doesn't make sense)

Probably something obvious - I tried from 'Format' menu changing from 'Paragraph' to 'Body Text' but it doesn't seem to stick.

FOUND IT: From MAIN APPLICATION window Menu...Edit...Settings...UNCHECK 'Use Paragraph format instead of Body Text by default' I must have checked it at some stage (or maybe it's the default)

Sometimes I enjoy a conversation with myself...but in any case maybe someone else could find this useful.
