Hi, I was trying to find a particular email and was playing with a couple of filters. I ended up with all of my inbox in alphabetical order. In other words, all the senders' names starting with A are at the top, and conversely all the Z' s are at the bottom. How do I put them back in the order received please? Many thanks, John.

My husband (DG) is 88 and beginning to have severe memory & analysis problems. I recently tried for three days, using his computer, to set up an account for him on the Social Security site, that I could oversee. It accepted a password, but kept asking for a 'backup code' that supposedly was 'assigned' - so I would have a second method to verify the account. There was no way, on that web page, that I could request a 'backup code' or ask for the '10 backup codes' that were supposedly given automatically. I wanted to simply get a letter that explained his SSA eligibility, so we could apply for Senior housing. I was able to call SSA and request the letter - but it will take 14 days by mail. We need it now - and I should have been able to simply download a PDF eligibility letter to print out. In less than 5 minutes, I was able to request and download an eligibility letter for myself on MY SSA account - but could not do it through his SSA account. I need to be able to communicate with SSA (& other agencies) and receive their replies through an email "AccountForDG@centuryxxxxx.net" that I can read in my email account "CuriousQuestor@centuryxxxxx.net). How do I set this up? Thanks in advance.

After a long explanation, I tried to add a file and lost everything. Starting over! After using TB for over 30 years, I accumulated a large number of personal folders to archive files to. Due to confusion on my part about pass words in Proton Mail and their Bridge, I had to reinstall my ProtonMail account into Thunderbird. Because all my personal folders were connected with the old "account" name, I didn't remove it, and the new addition seemed to be working fine.

After doing some house cleaning to remove duplicate and obsolete files, I wanted to move the folders attached to the old account name, under the new name. I thought I could carefully move my personal folders from the old account, back under the new Protonmail account. Sadly, that doesn't work like that. What I did find was that the original folders which come under the original "account", were created with an older version of TB, which put them in a folder on my HD. But the new default folders ("inbox", "draft", "sent" etc.) are mirrors of the Protonmail Bridge, which is NOT what I want.

So I need someone that knows how to either place the old folders back under the NEW "account", or how to create new folders that ARE on the HD, and then move the files from one place to the other.

Just to help clarify, here's the location of the old folders as per the "properties" info.

mailbox:///E:/thunderbird data/thunderbird/yetudx3p.default/Mail/Local Folders/Friends & family

You can see the address for this folder is on my Drive E: I can go directly to that address on my drive E and see each of the files.

imap://gshantz%40protonmail.com@127.0.0.1/Folders/2009

This folder is from the NEW account of Protonmail - bridge, and is obviously the web address of Protonmail. It is NOT editable, unlike the above location on my HD E:.

Any help or suggestion would be greatly appreciated, gshantz

My Charter.net mail has suddenly started to come into my inbox and automatically is moved to trash by Thunderbird. I do not have antivirus, i have not changed any settings, it is POP.

hi, snap thunderbird 155.0-1 ubuntu 24.04 keeps asking for passwords of all email accounts after upgrading thunderbird. all passwords are correct and they were not changed. the issue started today after thunderbird was upgraded to 155.0-1. this new version seems to have touched on oauth: https://www.thunderbird.net/en-US/thunderbird/155.0/releasenotes/

What’s New

- S/MIME popup shows signature, digest, encryption algorithms and key sizes

- Default address book for manually added contacts configurable with mail.addr_book.add_item_default_uri

- Enterprise policy DisableQRExport can disable QR export

- OAuth add-ons can override built-in settings for selected domains and hostnames

- Manual account config streamlined with Exchange, Graph, and custom OAuth support

- Custom OAuth support for IMAP and SMTP servers

- PKCE and external browser fields added to custom OAuth settings

- Enterprise policy DisableExperimentalFeatures for disabling experimental features

any idea how to fix this? thanks

Thunderbird won’t open because it wants a Primary Password which I have never had to do. I went on another computer (the one that I am currently using) and generated a password for Mozilla. I tried that but it still would not open. I have restarted the computer 3 times. When it asks for the pass word, I have entered the new one for Mozilla with no success. I have tried the one for the main opening of the computer with no success. When I close the small window that asks for the Primary Password, the spinning beach ball of death shows up and eventually (maybe 10 minutes) it has to be forced to quit.

Yesterday, 4 Sept a problem developed with my Thunderbird email, namely, when new messages were received they went directly to trash and not to my inbox, i have not tinkered with any settings, The program is on an ASUS laptop, operating Windows 11 pro.

Advice on how to fix without losing all my mail folders thank You Kenneth E. Smith

Enclosed are jpg copies of the current sets of filters failures in my TB email program.

TB Error0 shows the 6 emails that have arrived and are placed in the INBOX. However, each of these has a corresponding filter set up to move them upon arrival to a separate subject email mailbox.

Note: If I highlight the INBOX and then go to Tools > Run Filters On Folder ... all of these INBOX email messages will be correctly filtered and moved to their respective email mailbox, BUT each of them is shown as having been "read" and unless you pay close attention, you may not know where these INBOX emails were sent.

I am also enclosing TB Error1 & 2 that show the last couple of days message filtering errors.

I can find nothing wrong with how each of these filters are set up, yet they seem to consistently fail to operate when new emails arrive.

Note one of them is for incoming emails from ... schiffsovereign.com. I have edited this filter repeatedly, even deleted it and re-input the information. Yet the filter never takes hold and does what it is designed to do. I am enclosing a jpg of that specific filter as TB Error3

I am looking for suggestions on how to fix this problem.

Thank you and best wishes,

I am unable to send Email. I am using THUNDERBIRD app..My Email address is [redacted from public] @talktalk.net. I am receiving mail but cannot send.. I have a message that reactivation is required after being blocked. [ have paid my subscription but still blocked. Thunderbird version 155.0

I'm currently on Thunderbird 155 and previously I just had one email account configured and cards view was working fine. However, after adding an additional email account (gmail), which displays fine, my original account is now showing my name in the cards view, instead of the sender. I've tried clearing the cache, repairing the inbox, but that didn't fix it. If I switch to table view its fine, I see the column for "From", although the new account displayed "Correspondents" instead of From, but I switched them to using From to make them consistent. Still not showing correctly for the original account.

My business has two domains. I can send email to a Gmail account holder using the primary domain with no issues. But amy emails from what I call the "secondary" domain below are treated as spam. This occurs with two different email addresses using the secondary domain.

Both domains are hosted with Bluehost. Exhaustive research has revealed the following:

• Settings in Thunderbird are exactly the same, e.g. ports, security, SSL/TLS, etc. for each domain.
• There is no subject line or content that could possibly be regarded as spam.
• MXToolbox indicates that the secondary domain is not on any blacklist.
• Extended support via Bluehost reveals that SPF, DKIM, and DMARC records are all correct.
• Email sent to a Gmail account using the CPanel (Roundcube) is not flagged as spam. Only emails sent via Thunderbird are flagged.
• Emails sent to a Gmail account from the secondary domain using my mobile phone, but still on the same network/IP address, are not flagged as spam.
• If I first send an email to one of the secondary domain emails FROM Gmail, then reply to it, the reply is not flagged as spam.

After many hours of head scratching (and later, head banging), I am pretty much at my wit's end with this problem. I'm an electronic engineer but this one is definitely out of my wheelhouse. Any help would most certainly be appreciated!

Thanks in advance, Don

I use IMAP to grab my mail, if that's important.

In the last couple of days, my normal method of deleting messages from my Inbox, right-clicking on the message and selecting the trash can icon, has stopped working: the message disappears for a moment, then reappears. I can delete it by dragging it to the Trash folder in the folders pane on the left.

I've followed the instructions given in several postings here, including deleting the Trash and trash.msf files, doing that and then creating an empty txt file called Trash (no .txt), and using Repair Folder.

It just now occurred to me to disconnect from the Internet and try to delete a message. It worked fine?!

Thunderbird not connecting to server. It says timds out and an error occurred connecting to mobile.charter.net. I can neither send or receive emails. This started 8/20/2026

All of the incoming messages are going to Trash. This includes messages I have not indicated as trash. I get no new messages to my inbox. Started today, 09/04/2026.

Starting today (September 3), ALL of my received emails are being put into the Spam folder instead of the Inbox.

FYI, I have been running Thunderbird (TB) for years and have not recently set up any new filters.

I'm currently running Thunderbird 64-bit version 155.0 under Windows 11 Home version 25H2. I am also running Bitdefender Total Security, but I have turned off its Antispam function, both under my usual Standard User account and the Admin account.

I have tried:

1. Going into TB Settings|Privacy & Security|Spam and clicking on "Reset Training Data." 2. After closing TB, I deleted the training.dat file in my TB profile folder and restarted TB. 3. Right-clicked on my Inbox and Spam folders and clicked on "Repair Folder." 4. Exited TB, copied my profile folder to an external HD, uninstalled TB and reinstalled TB after downloading from the official download site. 5. Rebooted my PC.

None of these approaches has worked to solve my problem.

Thanks for any help you can give.
