Thunderbird 152.0.1 (64-bit) Build ID: 20260630165458 Windows 11 IMAP account hosted by Wedos

I found what appears to be a reproducible bug when forwarding messages with attachments.

Steps to reproduce:

1. Open an email with a JPG attachment. 2. Click Forward. 3. Save the message as Draft (IMAP Drafts). 4. Without closing the compose window, save the draft again.

Result:

The second save always fails with:

"An error occurred attaching 20260520_123800.jpg. Please check whether you have access to the file."

Error Console shows:

Failed to fetch attachment NS_ERROR_FILE_NOT_FOUND url=file:///C:/Users/<user>/AppData/Local/Temp/nsmail-1.jpg

I also observed that after the first draft save Thunderbird deletes:

C:\Users\<user>\AppData\Local\Temp\nsmail-1.jpg

However, the compose window still references this deleted temporary file.

Additional observations:

- Creating a new message and attaching a file from disk works correctly. - Forwarding a message without attachments works correctly. - Removing the forwarded attachment and attaching the same file from disk also works correctly. - Closing and reopening the saved draft restores normal behavior.

This appears to be a bug where the compose window continues using a deleted temporary attachment instead of the attachment stored in the IMAP draft.

Can anyone reproduce this with Thunderbird 152.0.1?

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.

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.

I would like to set up an existing Gmail account in Thunderbird.

The following window appears: (see Image 1)

I click the next button, and the next window is: (see Image 2).

How can I sign in to Google? Perhaps in a different way?

Hi, I've used Mozilla Thunderbird for years to import all my Tiscali (talktalk) emails with no problems.

Now, I can’t get any emails as the server settings have changed.

What server settings do I now need to get my system working again?

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?

HI all

I've just bought a new 24" iMac desktop and it's running Tahoe 26.5.1. I'm using Thunderbird 152.0.1

Everything migrated fine from the old machine, but on the old machine a great many of my subfolders under Local Folders were disordered. Now, I've used 'reset folder order' to fix them, but within those subfolders, the next level of subfolders are disordered. Manually dragging and dropping makes it worse (didn't know it could get worse, but it has...) and when I took advice and looked for the 'Manually order folders' add-on, it says it's not compatible with my version so now I'm stuck. I have ongoing conversations with several hundred clients and cannot work if I cannot file and search email alphabetically, it's a disaster. I'd send a screenshot but the client names are confidential. Can anyone please help??? The top line of subfolders under Local Folders are fine, it's the folders within those subfolders that aren't. Thanks in advance!

I'm trying to add my godaddy account, the email format is firstname.lastname@mydomain.com, receiving works fine with IMAP, but SMTP isn't working (I probably have to ask GoDaddy to enable the SMTP option somewhere because I can't find it). I was using this account fine with Outlook on my windows desktop.

Since it's working fine in Outlook, I was trying to get thunderbird to let me setup an exchange account but it's not letting me as it can't find the settings and dumps me to the manual config area. I'm assuming that since it worked in Outlook, Outlook is using the Exchange path and I can't get that option to appear in thunderbird when adding the account, nor can I manually add an exchange account.

Here are the details and troubleshooting I've done.

I'm on EndeavorOS and installed thunderbird with pacman, help-> about shows I'm on version 152.0.

Thunderbird 152 fails to discover a GoDaddy-managed Microsoft 365 Exchange Online mailbox. Exchange AutoDiscover reports "Cannot contact server", falls back to IMAP hostname guessing, and eventually produces an invalid hostname error instead of offering an Exchange account. SMTP AUTH is disabled on the tenant, so the IMAP/SMTP fallback cannot be used. When it fails it brings me to the manual add screen and defaults the hostname in there as .totalitconsultingllc.com (which is shows red errors because the hostname is due to the leading .)

The SMTP error: 535 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Tenant

dig autodiscover.totalitconsultingllc.com resolves correctly to Microsoft Exchange Online. autodiscover-s.outlook.com returns 401 Unauthorized (expected). Thunderbird logs: Cannot contact server no SRV record AggregateError: No Promise in Promise.any was resolved Thunderbird falls back to guessing IMAP/POP/SMTP hostnames instead of offering Exchange.

Here is the log while trying to add the account:

Thanks for your time and attention to this,

PRELUDE: I have several email accounts. All accounts display properly, except one. Yes, this is similar to my question about bottom of the far left [of emails] list of emails - but this is different.

On the far left of Thunderbird is a list of all my email accounts with "Inbox" etcetera. Each email account shows it's Inbox/Sent/Deleted/ except for 1 account. The problem email account only shows it's Title and Inbox northing else. Yes, I tested it and sent emails to it, and used the problem email account to send, create a draft, and they don't show..

The image explains it.

Thanks for reading this ~r

I recently upgraded to version 115.10.1 and it is driving me utterly insane. It repeatedly turns on threading. I turn it off for a folder, next time I log in it's on again. I turn it off in a folder and copy that setting to all other folders, but it turns itself on again. Others say turn it off in Settings/Appearance. But I don't seem to have Settings/Appearance.

How do I stop this? Or is there a way to find out what version I was originally running and go back to that. I hadn't upgraded for a good while but my old version was much better. This one is also really slow and I hate the tiny text.

- 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 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.
