Hello Thunderbird Support, I am experiencing a severe IMAP folder synchronization loop with my Yahoo Mail account ([redacted]@yahoo.fr) inside Thunderbird. Yahoo Support claims the issue is caused by Thunderbird's folder mapping, so I am reaching out to you for a solution.

1. 1. The Problem:

The system-protected folder "Bulk" (Spam) has somehow been moved or mapped as a subfolder inside the "Trash" folder.

• In the Yahoo Mail Web UI (Chrome), the subfolder is invisible, but the Trash directory shows an arrow (^) indicating a child folder exists.
• In Thunderbird, the Bulk folder is clearly visible inside the Trash folder, marked with the flame (Junk) icon.

1. 1. What goes wrong:

When I delete spam messages via Thunderbird, they get trapped inside this nested Trash/Bulk directory. If I try to delete or empty it, the emails disappear but the folder itself cannot be removed.

1. 1. Steps tried so far that failed:

1. Attempting to delete or rename the Bulk folder inside Trash gives the server error: [CANNOT] DELETE failed - Mailbox is reserved. 2. Using Shift + Delete on the folder is rejected by the Yahoo server. 3. Unsubscribing from the folder via "Advanced IMAP settings" -> "Show only subscribed folders" fails; Thunderbird re-downloads the structure on the next sync. 4. I have completely deleted my old Thunderbird profile folder and created a brand new one using thunderbird.exe -P. Upon adding the Yahoo account via OAuth2, Thunderbird immediately pulled the same broken Trash/Bulk structure from the server again.

Since Yahoo refuses to help and claims Thunderbird caused this mapping loop, is there a hidden config setting (about:config) or a database override in Thunderbird that can force the server to release or move this reserved folder back to the root directory? Thank you for your assistance.

Hi everyone,

I'm trying to access some old emails which I know were stored on a laptop running Ubuntu 20.04. The laptop was wiped years ago but I have restored the data from a backup in October 2023 or thereabouts.

When I try to open Thunderbird it throws up a dialogue saying 'You have launched an older version of Thunderbird' suggesting I need to re-create my accounts. I just need to access the emails from the restored data and I'm worried if I connect to the mail server that my settings might just erase the emails all over again.

What should I do?

Thanks in advance. Any help would be gratefully received.

I am not able to send emails the last couple days. Any ideas on how to fix this? My incoming mail works fine, but when I try to send and email, reply or forward, it will not send.

Thanks!

I have successfully set up 3 email accounts using my default domain. When I try to use an email account that uses a second domain I can't send or receive emails. This account required manual setup which I did but it does not work. My web hosting is with Namecheap and I do believe settings at that end are correct. Any help would be appreciated.

Seit kurzen kann ich beim senden einer Nachricht keinen Anhang mehr hinzufügen, es öffnet sich kein Auswahlfenster mehr, was am 8.09.26 das letzte mal noch funktionierte. Weder über die Büroklammer, noch übers Menü Datei-Anhängen-Datei(en). Es passiert einfach Nichts.

In der Update-Chronik sehe ich am 19.09.26 ein Update auf 153.1.1esr !? Habe deshalb das neueste Update 153.4.0esr heruntergeladen und installiert, aber ohne Erfolg.

Hat jemand ne Idee? Ausgerechnet jetzt wo ich in den nächsten Tagen die Funktion dringend bräuchte...

Vielen Dank

Running Windows 11 Home and Tbird 153.4.0esr. Tbird configured with IMAP. I have many years worth of emails stored in my Tbird profile folder. Profile folder is 25 GB.

I want to delete the bodies of all emails in the profile folder but retain the subject lines to minimize the size of the profile folder (while keeping bodies of all emails on the server). Then I can retrieve any email from the server.

Anyone do this successfully without losing emails? Is there a step-by-step procedure for doing this on the Mozilla website? (Google is giving me an Ai answer but not a link to a Mozilla answer.)

As of the latest update, the attachment toolbar button in a new mail window does....nothing. Nada. Click it, nothing. I have to drag the attachments from (say) Desktop to the new message window. Works, but...so should the toolbar buttons, which used to.

Tried turning off all addons (i.e., troubleshooting mode) - made no difference.

I have been having all my email transferred from Yahoo mail for more than a decade, it used to be Frontier net, and i didnt want to change my email, and i havent, so i transfered it on 3 devices because i am very used to the thunderbird format. It still works on my android phone and my HP laptop, but thunderbird will not allow me to sign in to yahoo mail on my PC which is what we use the most for our email, for some reason yahoo made some changes and required a new sign in so i did that on the other 2 devices, however, when the sign in box from yahoo pops up on our PC it always says " OOPS something went wrong" and i called yahoo and they verified it was not them. Which leaves Thunderbird to fix the problem. Please address this as i still Do Not want to change my email address or the Thunderbird Mail which we are used to. Some things are okay just as they are, so i would like some help from your end. Thank you, Richard Sessums.

Today Thunderbird will not download emails. Yesterday no problem downloading emails.

Windows 10. Thunderbird 153.3.1esr (32-bit) Email is POP3. AV is Malbytesware. I added what I think is the Thunderbird folder to exclusions ("Allow" in Malbytesware). I deleted the global-messages-db.sqlite file. Thunderbird recreated it, but the problem persists. I disabled Malbytesware and still cannot download emails.

Plenty of empty space on my C: drive where Thunderbird lives.

To the best of my knowledge, folder privileges have not changed today from yesterday.

Running Thunderbird as an Administrator does not fix the problem.

I need help to fix this. Please, if you have a suggestion, give me a few "click this..." steps so that I can follow you kind advice without having to come back and ask you again, "How do I do that...?"

For years I have been attaching message files, pics., etc. by clicking the Attach button and browsing to the target. Now I have to drag and drop the attachments as the Attach click is useless.

Suddenly I can't attach images (or anything) to outgoing emails. I do this a lot and it worked fine all day yesterday, then stopped in the evening. When I click the Attach button, nothing happens. I've deleted 1000s of emails and compacted the folders, nada. My Thunderbird is up to date v153.4 on Win 10. Any ideas? Thanks, Andy.

// File: Thunderbird.js (Optimized Version) // Executes Thunderbird from a USB drive using the local USB profile path.

var Shell = WScript.CreateObject("WScript.Shell");

// Returns the drive letter or directory where this script is executed var USB = Shell.CurrentDirectory;

// Ensure the path ends with a backslash if it doesn't have one if (USB.charAt(USB.length - 1) !== "\\") {

   USB += "\\";

}

var ThunderbirdVersion = "07";

// Construct absolute paths to the executable and the profile var PathToExe = '"' + USB + "Thunderbird\\" + ThunderbirdVersion + "\\Programme\\thunderbird.exe" + '"'; var ProfilePath = '"' + USB + "Thunderbird\\" + ThunderbirdVersion + "\\Profile" + '"';

// Combine the executable path with the portable profile switch var Command = PathToExe + " -profile " + ProfilePath;

// Run the application (0 hidden window state, false to not wait for execution to finish) Shell.Run(Command, 1, false); Shell.RunThunderbird.js

In Thunderbird, the “attach” button stopped working when sending a message, although the “drag and drop” feature still works. Could you suggest what the problem might be?
