When I double click on an email in my inbox, a new reply email is being displayed with a yellow message across the bottom saying:

   "A unique identity matching the From address was not found. The message will be sent using the current From field and settings from identity XXXXXXXXXX."

This happens only on my default account.

What can I do to get the email opened in a new tab as a default? See the attached context menus

Thunderbird: 140.0.1 (64-bit) Windows 11 Pro

Hi all, I have a client who uses Thunderbird and wants to close his orange.fr email address, but has thousands of emails he needs to be able to continue to refer to / archive. I advised to move all the emails from the IMAP server/inbox folder, to a Local folder in Thunderbird. Having done this, I tried to remove the account, did NOT check the box “Remove Message Data” and (wrongly assumed) there would still be a way for him to see his orange.fr emails in a local folder somewhere, but they all disappeared. I’ve tried to trace the path for the local folder but can’t see a way to see them once the account is removed. Can any suggest the best way to GUARANTEE that he can close his orange.fr email account and still retain his old emails? I’m guessing that if he closes the account but doesn’t remove it from Thunderbird, the account will retain the local folders but will be unable to connect to the orange.fr email address. I suppose that would be a solution but I’m guessing Thunderbird will throw a connection error every time it opens? is there a neater way? We would prefer to avoid trying to export them to another mail client.

Any suggestions / advice greatfully received. I’m just nervous that he doesn’t lose access to his old emails after closing his orange.fr email account. TIA Russ

I'm trying to better understand how Thunderbird communicates that messages are deleted to the servers of the respective email accounts configured as IMAP. Specifically, it seems that when moving a message from an IMAP folder, such as an Inbox, to a folder of a different email account or a Local Folder, the message disappears from Thunderbird but doesn't immediately get deleted from the server (I am checking by logging in through a browser to the email's web interface). Depending on the email provider, it may be marked or flagged as "deleted" or in some cases it just remains in the inbox (in outlook's web interface, for example, I can't tell if a message has been marked as deleted or not). Only later, after right-clicking on the respective inbox in Thunderbird and choosing "Compact" it deletes the message from the server.

I'm a bit confused now: All of my accounts are using maildir (https://support.mozilla.org/en-US/kb/maildir-thunderbird) as storage format, which I selected prior to adding any account. According to the information here (https://support.mozilla.org/en-US/kb/compacting-folders), "Compact does not apply to accounts using the maildir storage format". So for maildir accounts, why do I have a "compact" option at all and how come it doesn't delete messages immediately? Or perhaps I'm misunderstanding either what compact means or maildir or (probably) both? Is there a way to have Thunderbird simply delete (not just "mark as deleted") moved messages instantly?

I was under the impression that since maildir stores essentially one file per email message, that it would function like file management on a computer, so when moving a message from folder A to folder B the file/message would disappear from folder A, not that it would keep a copy "marked as deleted" in folder A. If anybody could explain this I would be most grateful.

Entsprechend der Einstellungen sollte erkannte Junk Mail aus dem Junk Ordner nach einem Tag gelöscht werden (wie es auch in der Thunderbird-Anleitung beschrieben ist und wie es in der Vergangenheit auch war). Aber die Junk Mail wird seit einem der letzten Updates (z.Zt. 138.0.2) nur in den Papierkorb verschoben, statt daß sie gelöscht wird ... - was aus meiner Sicht keinen Sinn macht. Wie kann man diesen Makel beheben? Danke im voraus für jeden Hinweis.

According my settings the junk mails in junk folder should be deleted after one day. But - instead of deleting these junk mails - the junk mails just move to trash folder (which then must be cleared manually) - absolutely nonsense !! My thunderbird version 138.0.2 - before update to this current version, the junk mails have been DELETED (!!) according my settings and NOT moved to trash

I have used Thunderbird for years. Within the last couple of weeks I have noted 2 issues. 1st is the calendar issue with Reminder function. Reminder that have been listed w/ reminders, and repeated, for awhile, suddenly don't have the REMINDERS activate. They have in the past. Now, old events with REMINDERS, don't have the reminders activating. Nothing on the event listing has changed. I have reentered the event listing with no success in getting the reminder to activate. Interestingly enough, it doesn't affect ALL the events: just some. Same with ALL NEW EVENTS. Sometimes the event reminder activates and sometime not. Checked all the settings, version is up to date. I'm flummoxed.

2nd is addressing email. Names I have had in my address book for years, while coming in during auto-fill, are asterisked as not in the address book. I have reentered an asterisked listing but it still shows as not in the address book. Once again, it doesn't affect all listing, just some. I haven't anything & the version is up to date.

I've got a gremlin somewhere, but not adept enough to take a deep dive into operational settings.

Hallo,

ich bekomme beim Starten von Thunderbird (bzw. beim Anklicken der Taskleisten-Verknüpfung) folgende Fehlermeldung:

„Diese Anwendung konnte nicht gestartet werden, da die Side-by-Side-Konfiguration ungültig ist. Weitere Informationen finden Sie im Anwendungsereignisprotokoll. Weitere Details können auch mit dem Befehlszeilentool sxstrace.exe angezeigt werden.“

Ich nutze Windows 10. Thunderbird wurde möglicherweise gelöscht oder ist beschädigt. Wie kann ich den Fehler beheben?

Danke für eure Hilfe!

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).

Hello. Since calendar category colorization is not very visible ...

... I created separate calendars for every category. This is semantically wrong but has a nice look – events are fully colored by category:

I now regret this choice and want to correct it:

I need to move >1000 calendar events from calendar "medical" to my "home" calendar and (at one go) assign the category "medical":

from [calendar: "medical" / category: none] --> to [calendar: "home" / category: "medical"]

How can I do this ?

How is this supposed to work? I am hoping to have a couple of folders from my IMAP configured email account automatically synchronized to LOCAL FOLDERS. But under the 'Synchronization' tab there are not a lot of options, and really only a 'download' button. But does that really synchronize? prevent duplicates? Someone smarter than me, please advise? Thanks in advance John

Hi, Can't understand what's happening with "search" I find in "account" a "none" with 2 old mails I thought effaced, but on clicking "can't have a value" the titles and first lines are shown, however on clicking on title I get "no message found" same with "show as a list" These 2 mails are also in a folder with same problem. How can I clear up and try to understand "search"

I'm using version 140.0.1esr on macOS Sequoia 15.3.2. The problem is very simple. When I compose an email, hitting return puts me at the center of the next blank line. If I type, the text is all centered from this point on. Thunderbird didn't do this in the past, so I either inadvertently changed a setting, or the behavior of Thunderbird has recently changed.

I really have no desire to spend time getting to know Thunderbird better. Like most people, I want to compose completely unstructured text-based email. (If I ever wished to add structures, which I doubt I ever will, I'd prefer markdown to HTML, like everyone else in the known universe ...)

Ideally: there is an easy fix by changing a setting. Second best: There is an alternative email program to Thunderbird, perhaps text based, that can read Thunderbird mail archives. Third option: There is an early version of Thunderbird that still runs on current versions of Mac, before Thunderbird began including text formatting in email composition (along with all of the other distractions that have be degrading the quality of Thunderbird for a very, very long time).

Why is everything broken after an update? So annoying and prevent me from making a donation.

There are 3 buttons, none of which are useful.

Can anyone free me of this Welcome to Freedom?

I'm using thunderbird on windows on PC and on my lap, on lap i dont have monthly calendar on side panel just today date, when i click bottom oriented arrow monthly calendar is popup without signatures of events, how can i put this calendar to stay on sidebar with events like on my PC, also i tested width of this panel, thought if i make it wider it will show but no :c

I try to access my messages from an outlook.com account with Thunderbird mac. I get the error message "the STAT command did not succeed". This happened suddenly today without changing any parameter. POP is enabled on this account. Moreover on another mac with Thunderbird everything is correct with the same account. Cookies are enabled I tried changing OAuth2 to normal and changing back. No sucess. What could I try next? Thanks.

The last few days most of my emails have been tagged as ***SPAM*** and automatically moved to my Junk folder. I have to be sure to check that folder. I've tried "training the app by moving valid email to the inbox but the problem persists.

I am unable to modify the font color that I see in a email. However, it shows for others. And it copy/pastes - I can change a sentence to blue, it will appear to me black, I can send it to another and they see blue; copied to me I still see black. I can copy the text and put it into word, alter it, put it back in Tbird and it all seems black to me all along, but when I send to another, they see blue. (I should maybe put it in a text editor to inspect code there???)

But I think a clue is - apologies if this is a misdirect, but just before noticing all this, it happened that when I used Constant Contact to send me a test email, the background color of that newsletter is clear -- no color. MORE, when I lookup old emails that had the same background color, while once they were colored, they now appear all clear to me. More, when I go to the gmail server, those test emails look fine there. Others receiving the tests fo not have the color problem. Oh, and the "real" newsletter also still has the color problem, when sent to me and viewed in Tbird.

SO. It is a my-Tbird problem.

I have tried to follow old threads, looking for old settings regarding color and overriding; cannot do it.

I am using Tbird 140.0.2

Can anyone please help me? THANK YOU SO MUCH!!!

Also, tried the window-closing order-of-operations thing (for font color change) but it's really not that at all....

Also, following others' threads, I got into a colors setting and tried resetting that to default but the problem persists.
