- Thunderbird set up 19/05 & email/ history /folders downloaded - Moved from DNS to GANDI Email server provider this week but now all folders/historic email are no longer visible in Thunderbird email - How do I get them back and how do I synchronise Thunderbird & Gandi so that emails shown in WEBMAIL include all History and not just new emails since Gandi switched on? Thank you.

Quick Filter does not return correct results in Unified Inbox (Thunderbird 140.12.0 ESR)

I'm using Thunderbird **140.12.0 ESR (aarch64)** and believe I've found an issue with the Quick Filter when searching the **Unified Inbox**.

• • Steps to reproduce:**

1. Open the **Unified Inbox**. 2. Open the Quick Filter bar. 3. Enter a search term (e.g. "maddy").

• • Observed behaviour in the Unified Inbox:**

• With no "Filter messages by" options selected, entering a search term does not filter the message list.
• Selecting **Sender**, **Recipients** and **Subject** still does not return the expected email.
• Selecting **Body** changes the results after a delay, but the expected email is still **not** returned.

If I open the **actual Inbox** containing that same email and repeat the search:

• The expected email is found using **Sender**, **Recipients** and **Subject**.
• When **Body** is selected, the search takes longer and eventually returns additional matching messages, including the expected email.

This behaviour is reproducible with multiple search terms and suggests that the Quick Filter does not search the **Unified Inbox (virtual folder)** correctly, even though the same search works in the underlying physical folder.

Could you please confirm whether this is a known issue or a bug?

I have a particular need to periodically run junk mail filters on a folder in Local Folders that I know will contain mostly junk mail. According to a search engine, the command to do filtering on particular folders should come up in a junk mail tab when you right click on a folder and look under properties. When I right click on a folder, however, I never see a junk mail tab under properties or anywhere else. Where to I find the command to do junk mail filtering on a specific folder? Greatly appreciate any assistance.

I am unable to access my mails on Greenby with Thunderbird and I suspect the password is incorrect. I can read my mails on the Greenby server and know the necessary password but cannot work out how to enter this into Thunderbird! As I am no expert, a simple guide would be most appreciated! Thanks in advance. Roy

Thunderbird is very glitchy and slow after the latest update - Thunderbird 140.11.1esr (20260522210329)

Especially, when I get a new email, Thunderbird stops responding for 5-10 seconds and then starts working.

I am using Windows 11

I have a desktop that is windows 10. I use Mozilla for four email accounts, 3 of my accounts work fine. My problem is with TWC. Emails sent/forward and cant save drafts often fail. When I sign into spectrum webmail, my Mozilla TWC account works again for a while. This started about 2 weeks ago. I'm using version firefox version 151.0.2. I've eliminated Spectrum as being the issue and all my settings are correct. Thoughts?

The system was working fine. The next day, when starting Thunderbird (TB, the status line shows logging in to server but loops; no errors or messages, Thunderbird is 'locked out' spinning. I see the normal INBOX page, but logging in never completes. NO CHANGES were made to TB accounts or settings. I have re-installed TB, re-booted, but no change. I cannot check/change any of the accounts or do any further 'debugging' because TB is spinning. The server login is fine because Webmail can be used. Internet connection is fine, because browser works. 1. How can I stop TB from trying to login at start up? 2. What could/would cause this behaviour?

Any suggestions much appreciated.

Hello everyone,

I am hoping someone can help me recover some EXTREMELY important emails for a legal matter. I was trying to export an entire nested Gmail label (WORK/TNC/TNC DISPUTE) to PDF.

It's a lot of emails spanning from April 2024 that I had painstakingly been going through and labeling to get them ready to print to use as evidence for a work dispute. When faced with the task of having to print all those emails to pdf, one by one, I wanted to chew my own arm off!

I'm convinced there must be another way to bulk print to pdf......and so I went down a few rabbit holes in search of my quick fix.....(I'm not trying to be lazy, I just have very little time left to get this done, and right now I'm losing the will to live if my reality is that I will be busy with this till the end of time.)

I read different threads and questions over the internet and found information that led me to Thunderbird. (Hi, Thunderbird :). I know there are paid apps or extensions that can bulk print to pdf, but I unfortunately don't have the money to pay for them (i.e. the work dispute - salary has been frozen for over 2 years and resignation was denied, so no income and held hostage by my employer - the emails I have lost are literally my future!). Sorry, enough of the why.....

I DID THIS:

So I read that I need to to create a folder in Thunderbird's "Local Folders" with the same name, and simply drag and drop the label from the original label to the local folder label (I did all of this in Thunderbird.

Unfortunately, this went VERY wrong. At first it seemed like it was doing something, but it didn't really do anything that I am aware of.....There was nothing in the local folder I had created and dragged the label to, there was nothing in the original label folder (everything was empty). I died! Then comforted myself with the fact that it's still in GMAIL.....that was the naive, optimistic me talking..... Headed over to Gmail, saw my label name, sigh of relief, clicked on the label name.....DIED 10000000000000 x over.......I continued to cry for the next 4 hours...

.That was the 12th of June.....I'm still trying to get them back.....I have been able to find a few bits of info here and there.....I just don't know how to get them back into Gmail for me to never try be so foolish again!!! (Until someone maybe shows me how to bulk print to PDF?????)....

Here is the current situation and the technical details of what I've found so far:

What happened:

Thunderbird executed a "Move" command instead of a "Copy".

The TNC DISPUTE label is in my Gmail web interface (the emails are not in the label, nor the the Trash and none of my settings anywhere are set to delete permanently etc., on exit).

The Local Folder in Thunderbird shows up on my screen, but it is completely empty.

What I have discovered in the background:

Account Type: IMAP connected to Gmail (*********@gmail.com). (i've replaced my email address name with stars to not put my private email on a public site)

The Local Files: I found the tracking path imap://**********%40gmail.com@imap.gmail.com/WORK/TNC/TNC DISPUTE. I also found the raw file directories containing TNC DISPUTE (no extension) and the TNC DISPUTE.msf index file.

The roadblock I am hitting:

I read that deleting the corrupted .msf index file while Thunderbird is closed will force it to rebuild the index and potentially reveal the emails. However, at first I couldn't safely get into the folder to do this:

When I clicked "Open Folder" from Help > More Troubleshooting Information, Windows threw an error: "Explorer.EXE - There was a problem sending the command to the program."

When I try to bypassed Thunderbird and use the Windows Run dialog with %appdata%\Thunderbird\Profiles, Windows threw another path error and refused to open it.

I ended up reinstalling Thunderbird and it fixed the access profile issue and I can now access where the data gets saved from Thunderbird.....

I just don't know what to do from here to get my (previously local foldered misshaped moved) folder back in my Gmail. (safely - to not corrupt everything or worse....delete it permanently.....)

The details of the missing emails (contents of the label that did copy to the local drive I think):

Sorry for the long post, hopefully someone can help me go back in time and have my only issue be searching for ways to bulk print to pdf and not having to try restore the only emails that are actually worth being on there.

Google sent me an alert about my password being compromised. I changed it. It works everywhere except Thunderbird. I've been trying over and over to update the password with no luck. I keep getting the sign in popup and that results in a 400 error message - "The server cannot process the request because it is malformed. It should not be retried. That’s all we know." I opened Saved Passwords (named Saved loging in the new popup) and I deleted all the old passwords as one of the articles said to do to get started. So far I haven't found anywhere to enter my new password to open the gmail account. I've been at this for well over an hour trying all kinds of possibilities with no success. Suggestions?

7-1-26: Problem when I updated/downloaded Thunderbird 152.0.1. When I try to open, a dialog box asks if I want to create a new profile. By mistake I clicked the "new profile button" but didn't create a new profile since I want to use my previous profile just as with past upgrades. However, I couldn't move past that screen so I closed Thunderbird. Then when I try to re-open Thunderbird, I get that same dialog box and can't move forward. What can I do? Your assistance is truly appreciated, Rick

Hi, I have been running low on hard disk space due to the bloated Windows 11. I have been trying to clean up Thunderbird by deleting a bunch of saved emails and compacting, but the size of my profile folder is still about 3.5 GB. I looked at all of the subfolders under my profile and found a bunch of what I think is dead storage.

Under the MAIL folder there are 4 folders for what looks like my current Local Folders and 3 older local folders. Under the IMAPMAIL folder there are 4 folders for what looks like my 2 current email addresses and 2 older unused email addresses.

I looked under the account settings for the Local Folders and the 2 email addresses and have identified the 3 out of the 8 folders that are still being used.

So my question is, is it safe to just delete these apparently unused folders?

for some reason emails move from inbox to trash by themselves. I have posted this before and did not get any help to fix this. Has anyone else had this problem. I am not very computer savvy so please if you can explain in plain language. Very frustrating. Thanks ahead of time

When I send photos from my phone to my imac inbox, same email address, or when a third party sends me a verification code, "get messages" is very slow showing results. Sometimes minutes, so I have to go through several verification attempts. The primary email account is gmail. My ISP is comcast.net. I don't know if this matters, because slow Get Messages is recent. It used to work very well

Dear community,

I'm planning to change my email provider and during the transition period I need to have the old and new accounts running concurrently. The help article states:

".....you can create additional profiles, each with their own set of account configurations, messages, etc. (Note, each profile can access multiple email accounts''.) .

but I can't see how this would work. If anyone can explain in simple terms how to achieve this, or point me to the relevant information I should be most grateful.

First, I have very limited understanding of software. I need very simple explanations.

Here's my issue. I use Thunderbird on my desktop computer. I have used the Import/Export > Options > Backup Scheduling function to backup my Thunderbird email to my USB/flash drive. I have labelled the backup folder on my flash drive "Thunderbird email backup." That folder contains numerous subfolders including: 1) calendar-data 2) chrome_debugger_profile 3) crashes 4) datareporting 5) extensions 6) ExternalMailFolders 7) Mail 8) minidumps 9) saved-telemetry-pings 10) scheduled-notifications 11) settings 12) shader-cache 13) storage.

Again, these are the subfolders created/named by the Thunderbird Import/Export backup. I HAVE NO IDEA WHAT THESE FOLDERS MEAN.

Here's what I want - it's actually very simple. I want to be able to see (read) my backed up email on my flash drive without using the Thunderbird installed on my computer. I want complete interaction with the backed up email without my desktop Thunderbird - or my online email account - being involved at all.

My understanding is that Thunderbird Portable is supposed to be able to allow me to do that. I downloaded Thunderbird Portable (from https://portableapps.com) to my flash drive but when I tried to access it the first thing it did was try to force me to put in my online account (POP?) information.

I don't want to do that. I just want to open Thunderbird Portable on the flash drive and have it realize that all of my backed up Thunderbird email information is right there in the same flash drive. I want it to just access and use what's right there.

I was really hoping that Thunderbird Portable would simply ask me where to look - in a very user-friendly way! - and I could tell it to go to my "Thunderbird email backup" folder on my flash drive (WHERE ALL MY THUNDERBIRD INFO IS!) and it would simply do just that and provide me with complete Thunderbird service for the backed up email.

Am I missing something? Can someone give me a VERY SIMPLE walk through to do what I would think should be a very simple thing? Thank you. Chris (6/29/26)

PS - I've read the Mozilla Support ARTICLE: Thunderbird Portable (Mozilla Thunderbird, Portable Edition) and other portable apps as alternatives (https://support.mozilla.org/en-US/questions/1285834) and it alludes in general terms to exactly what I want to do but it does not give any step-wise instructions.
