I have a 14 gig file downloaded from a client's google drive and want to know if I put those files into an external drive, will I still be able to open via Thunderbird software?

Should I open the zip drive first then put everthing into the external drive and THEN use Thunderbird via the external drive?

OR

Do I have to open the zip file first in my HD, and only be able to open using TB only from the HD

If there is an option as this is my first time and I don't want to mess up...Is there an option to speak or chat through the process?

Hello. I have been using Thunderbird for personal email on my desktop for some years now, but recently the client seems to download messages and then allow only a few for me to read. I don't think I have set up any SPAM or TRASH detection. Right now, in addition to my message downloads, the client is showing 3 messages as NOT READ - but which I cannot find to see! Is it something to do with the number of messages still sitting in my INBOX? I have around 3700 of them.

Just not sure how to solve this. I just tried to send a message from another of my email accounts - which was received and viewed fine. Attached is an image of my INBOX. Thanks for your kind help. Lee, West Sussex UK

Bug? Is there a fix coming. I move emails between different accounts all day long :)

As an intended workaround, I installed the beta version but the import of settings did not actually move over my configuration of views, toolbar settings, threading, etc. and that would take a quite some time setting up again.

j'ai changé de FAI et je voudrais mettre ma nouvelle adresse mail GMAIL et garder mon ancienne sur ORANGE en attendant qu'orange m'en refuse l'accès Vous remercie tous

I have a problems receiving and sending emails from and to externals users. However I don't have this problem with the emails receiving and sending between my coworkers (we have the same domain @spectratech.gr). We checked the SMTP settings (IMAP/POP3), SSL/TLS settings, updates and these setting seems to be ok. What could be the problem? thank you

Moin,

ich bin von Outlook umgestiegen auf Thunderbird, das lief soweit alles gut, dann wollte ich meine "alten" Ordner im neuen Programm anlegen habe dabei festgestellt dass Änderungen in Thunderbird ins Outlook übertragen wird, also ich ändere im neuen Ordner den Inhalt in Thunderbird ist die Änderung auch in Outlook ausgeführt, das ist sehr ärgerlich.

Ich bin mit der Bedienung von Thunderbird nicht so gut vertraut, das bedeutet wenn ich hier was ausprobiere hat das Auswirkungen auf die Daten im Outlook, in meinem Fall sind wichtige Unterlagen futsch.

I’ve got a minor but annoying Quick Filter button issue which just cropped up today out of nowhere, and haven’t been able to find an exact match for all these symptoms in any other problem reports.

Toggling my Quick Filter button works as expected, picking up the individual active filter buttons. However, in some instances of launching TB its on/off status indicator always displays as active regardless of individual filter button status. Weirder still, in other cases it always displays as inactive. It’s an intermittent problem, which always persists in one way or the other.

Further details:

- Problem is also present in safe mode, with the single plugin I use (CardBook) disabled.

- General display settings are “Theme Simple” and “Variant Normal” (not “Dark”).

- There are no automatic filters configured in “Tools > Message Filters”.

- Individual filter buttons are all working properly, including correct status indicators.

- Running current TB version (128.7.0esr 64-bit) on Windows 10 with all OS patches up to date.

An example:

Image 1: “Show only unread messages” button is active, and the Quick Filter button also displays as such (both indicators are correct).

Image 2: All individual filter buttons are inactive, yet the Quick Filter button still indicates a filter is active.

I’m stumped, thanks in advance for any help!

Hello, Since tuesday (2025 february 25) I can no longer send e-mails from my main account, whoever is the recipient. As soon as I clic on "Send" I get the message below: "Sending of the message failed. An error occurred while sending mail. The mail server responded: : Client host rejected: Access denied. Please check the message recipient <recipient address>". I did not change anything. I have the exact same issue on an other computer with the same Linux distribution (Xubuntu 20.04, both up to date) running the same Thunderbird version (115.18.0). What is weird is that I have no trouble to send e-mails from a secondary account, on both computers. I checked using openssl that the problem is NOT related to the smtp server. Anyone experienced the same weird issue? Thanks in advance for any help. Lucie

There has been an ongoing problem with the latest updated binary showing up on the main thunderbird.net for days after it has been released. This is a serious problem because users cannot access patches that keep them safe from security vulnerabilities. I've contacted the team several times and was told this was a replication issue with the site or the CDN. The issue still hasn't been fixed.

Today Feb 4th is yet another example. At the main Mozilla security advisory I see the release of TB 135 and TB ESR 218.7. https://www.mozilla.org/en-US/security/advisories/

When I go to Thunderbird Releases site https://www.thunderbird.net/en-US/thunderbird/releases/ and the main page and click on downloads, I see the OLD 128.6.0

This is a persistent problem and it makes the users of Thunderbird less safe, please fix this.

Mail arrives in the Spam folder. It is not spam. I click on Mark and click on It is not Junk. Messages move to inbox. Perfect. Now why are later emails with same email address again sent to the spam folder? Once an email is declared as not junk/spam, it should be cleared to go to the inbox. Can this thought/idea be incorporated into the next update? Thank you. Greetings from North Germany. Ken Yeager

Following a switch off and restart triggered I think by a Windows update, Thunderbird is not displaying any messages in my Inbox, though it is showing the number of messages in the Inbox title bar. 'Drafts' and 'Sent' all display correctly, but the 'Inbox' is blank with a grey icon of an envelope and the statement: "No message found". I am an IT novice. I looked on the 'help' pages. I have checked that no filters are set. I have right-clicked on the 'Inbox' title to display the menu with 'properties' at the bottom. I have clicked on that to bring up the dialog box with the "Repair" icon. It shows 'Inbox' in the 'Name' box but I note that the 'Location' box is blank. Presumably it should not be. Presumably it should show either the location of locally stored messages on my hard drive, or the location of the messages on the email server. I am not sure which. I have found the directory on my hard drive where I believe the messages are stored locally. The size of the file suggests to me that they are all there. The periodic 'Checking for new messages' is happening, but nothing is displaying, though a check via webmail shows that new messages are arriving on the server. What should I do to get my Inbox to display correctly? With many thanks, Iain

In my Google calendar, I have the automatic birthday calendar. The birthdays of people in my (Google) contact list will appear in my calendar. See the first attached image.

In Thunderbird, I have subscribed to my Google calendar (and Google contacts), but birthdays are duplicated in my Thunderbird (Google) calendar. See the second attached image. One birthday appears to be originating from the Google birthday (red) calendar, and one from my main/personal Google (green) calendar (which has two icons that I don't know the meaning of).

Why are birthdays being duplicated in Thunderbird?

In Thunderbird, I can resolve the issue by unchecking the option to 'Sync from <email address>' in the settings for the birthday calendar in my Google account. See the third attached image. This solves the problem for Thunderbird; see the fourth attached image. But then in my Google calendar, birthdays disappear. See the fifth attached image.

Is there a solution that allows the birthdays calendar to be synced correctly in both Google and Thunderbird without showing duplicates and without disappearing?

You don't even provide an option in your topic inquiry. I'm trying to uninstall per the Mozilla instructions to change to another version of Thunderbird. Apparently Mozilla has no interest in helping.006590

There is no item in the list.

There is no item in the selection.

No item.

It went away for a while but now it is back. When I select the text it usually (but not always) resolves. However it is a pain to keep stopping to do that.

I've tried the existing fixes but they either don't work or stop working after applied.

I'm trying to restore my Thunderbird mailboxes from my old (essentially dead) computer's backup to a new computer. My first attempt failed. I need to understand what went wrong and how to correct it.

I installed Thunderbird on the new computer and used Profile Manager to create a profile in the location where I want to keep it (in the Documents folder, to simplify backup). Then I found the place where the mailboxes were kept and copied my old mailboxes there from the backup.

Then I started Thunderbird. Instead of displaying my old Inbox and a list of mailboxes, it displayed a screen that prompted me to define my email account. OK, that's fair; if the account information wasn't in the files I copied, Thunderbird would have to do that. After I defined the accounts (there are three), I quit and restarted Thunderbird, and it displayed my Inbox and mailboxes.

But not quite as I expected. I expected to see the mail that was on the old computer when I last backed it up. Then I planned to download mail to get everything that came in after that. Instead I found that Thunderbird had erased everything I copied over, then downloaded the new mail without me asking it to.

Now what? The new mail is still on the server, so I can repeat the whole process if I have to. First, though, I need to understand what went wrong.
