Does Thunderbird have a limit on the number of members you can add to create an email group. I seem to only be able to add 7. Is it possible to create a larger group - e.g. up to 50?

Hello, I've installed Thunderbolt and added my Outlook account. However, none of the folders I created in Outlook have been copied over. Only the standard built-in folders e.g inbox, junk, sent etc were setup in Thunderbolt with all the mail from the other folders in the inbox. This is not very helpful.

How do I set up the Thunderbolt account so that the folders (and contents) are matched with the folders (and contents) in Outlook? Thanks

Thunderbird does correctly mark emails I choose as spam spam. Problem is, TB fails to move these marked-as-spam emails to the selected spam folder. I've searched for cures here but nothing helps. Now what Mozilla??? See attached pics...

W11 rig. TB updated today to 138.0.1 (64bit). All message on inbox show up ok, but all messages on the local folders are blank.

But I can access all email in all folder from my W10 rig which is running 128.9.1 esr so I know the msr files etc are not corrupted. This is only happening on the w11 rig

Repair approach makes no difference when tried through the w11 rig. Have rebooted w11 computer, reloaded TB several times. No change.

Need suggestions to get the W11 rig working with all messages. Thanks

I installed Thunderbird 138.0.1 (64-bit) on a Win 11 desktop computer yesterday and the column headers for the messages are not displayed. I have View/Headers/All, View/Layout/ Classic View, Folder Pane, Message List Header selected. How can I get access to the message column headers to display them and later select the ones I want ?

Thanks, Corey

I've been using Thunderbird for years. It connects to my gmail account using POP. I'm on a Windows computer using Windows 11 and Thunderbird says it's up to date with version 128.10.1esr.

For the past couple of weeks my Sent folder has been empty. Emails are sent successfully, they're just not stored.

I have searched for solutions but they all seem to deal with IMAP, not POP. I have found the folder (appdata\profiles etc) where the sent file exists, and it's there and very big. I tried copying it to a new name ("sent2") and asking Tbird to store sent messages there but it's still empty and not saving messages. I also tried deleting the sent.msf file and that didn't help either.

Any thoughts?

I am long time user of Thunderbird and currently using version 128.10. I am having trouble downloading and sending email either from Gmail or from my MS Exchange account as of late (May 2025). Email sometimes selectively downloads but I am no longer able to send email either through my Gmail of MS Exchange accounts as both the Gmail and exchange SMTP servers time out. This problem started with the previous versions of Thunderbird circa Nov/Dec 2024. A Thunderbird or Windows update resolves the problem for a short time but then the problem it reoccurs. Server settings are all correct and have been checked multiple times. I've deactivated Norton AV and firewalls, added and/or verified port exceptions but to no effect. This problems has resulted in many overlooked important emails until they've been double checked on webmail portal. Is trouble sending and receiving emails a broader issue with Thunderbird users and are Google and Microsoft deliberately making it difficult to use Thunderbird as an email client? I've seen older posts dating to 2023 reporting similar problems and I'm surprised that without changing anything on my end that this problem suddenly popped up. Any suggestions on how to resolve?

I can send mail via thunderbird but now will not get it from earthlink server? tried restarting app, computer and router, no help. My mail is in my web mail but not thunderbird

I downloaded 138.0. I can get email and reply to them but can't start a new message. New message button does nothing. I don't have any add-ons. This is the newest version I believe. Any suggestions?

Hello Frinds!

Please help me find a solution to a fatal Thunderbird crash that erased the Inbox folder and its subfolder structure. All emails have disappeared, and the cause is unknown. Tried "View" but did not help. Didn't find any local program tools to restore the before-crash-state.

Here are the details:

1. The incident happened due to a random, uncontrolled cursor movement in the bottom left corner of the program window using the "drag and drop" feature. There was no clicking involved. Or maybe it was a coincidence: happened when Thunderbird was upgrading.

2. The current version of Thunderbird Portable is:128.10.0esr on Windows 10 Home.

3. As a result of auto backup creation on the day of the crash, the backup was overwritten by the corrupted original.

4. The size of the main folder has not changed, so I believe the files needed for recovery are still available.

Is it possible that this disaster is the result of a version update? So so far, Thunderbird worked seamlessly.

Looking for help. So far, I have not been able to find a solution, including with the assistance of AI. Thank you in advance.

Best, Max

Receiving this error a couple times a day when using Thunderbird: "The folder 'Inbox' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

I can delete some emails but for the most part, everything in the Inbox cannot be deleted. I have looked at other forums but I haven't found a concrete set of steps to get this error fixed. I am not very familiar with the inner workings of Thunderbird, so more details on how exactly to get this fixed if possible would be appreciated.

The related link in Tasks does not open the corresponding email. Normally, upon clicking the link, it would open the email corresponding to the task I created but for some strange reason it stopped working.

I tried reinstalling Thunderbird but that has not helped. link text

Whenever I send an email from my em@ihmaxwell.com account, it automatically shows up with a logo alongside clearly taken from a notification from Jet2 about. flight booking! How do I get rid of this.

Since a couple of days I have a problem with Thunderbird. I can send normal emails without attachments and I have no problem, but when I attach, it keeps loading in 12%, as if it was checking the files, and from there it doesn't go beyond that until it gives a timeout error. I have tried with another email client and it has worked without problem from the same computer. I have paused the antivirus protection in case that was the problem, but it hasn't been the case.
