Subject: Thunderbird 152 – IMAP Junk messages are not automatically moved to Spam (T-Online IMAP) I am using Thunderbird 152 on Windows 11 with a Deutsche Telekom (T-Online) IMAP account. Problem When I manually mark a message as Junk (toolbar button, context menu or Junk column), the message briefly disappears from the Inbox and immediately reappears. It is marked as Junk, but it is not moved to the Spam folder. If I disable the option "Move new junk messages to:", the message remains in the Inbox and is marked as Junk, without the brief disappearance. Manual Move to → Spam always works correctly. Environment • Windows 11 • Thunderbird 152 • T-Online IMAP • ESET Internet Security • Only one Spam folder exists on the T-Online server. Troubleshooting already performed • Created a completely new IMAP account. • Verified Junk settings. • Verified the Spam folder path: imap://...@secureimap.t-online.de/Spam • Manual move to Spam works correctly. • Rebuilt the folder cache. • Recreated folderTree/folder cache files. • Performed IMAP resynchronization. • Tested with ESET mail protection enabled and disabled (no change). • Checked profile configuration. • Verified that the IMAP server directory setting does not change the behaviour. Additional observation The profile contains two IMAP cache directories: • secureimap.t-online.de • secureimap.t-online-1.de The current IMAP directory does not contain local Spam/Junk cache files, while the old "-1" directory still contains: • Spam • Spam.msf • Junk • Junk.msf Thunderbird also displays a greyed-out, inaccessible Spam/Junk folder which cannot be selected, subscribed or removed. Question Is this a known issue in Thunderbird 152 related to IMAP Junk handling or old IMAP cache migration after changing an account from POP to IMAP? If not, which log or additional information would help identify the cause?

PS: The POP account worked correctly before the migration to IMAP. The problem started only after switching from POP to IMAP. Rudolf.weinzierl-landshut@t-online.de

New W11 Pro pc, so new installation of Thunderbird. All profiles and folders moved over ok, but the Bin folder is an issue (main Gmail account IMAP). In my previous Tbird installation, I was able to right click the Bin folder, and be given the option of emptying said folder. Not now. The Spam folder does have the Empty option. Pics illustrate the folder list, what happens when I right click the Bin folder, and what happens when I right click the Spam folder, which does have the 'Empty Spam' option. I can highlight the messages in the Bin folder and delete them that way, but the right click option is shorter, easier... The only item I can find in the Thunderbird help pages tell me to delete the Trash and Trash msf folders in the profile - tried this twice, with no difference. It's a little frustrating... Any help would be welcomed, I guess I'm missing something really simple...

the thunderbird on the old laptop still showes all emails back until 2022. after copying the profil to the new laptop as described on the mozilla video, thunderbird took all settings but at one of the email accounts it just showes emails back to may 2026. The rest has disappeared. I tried all fixing experiences I found on internet but it doesn´t work. This special Email account had the pop3 - setting.

When I create a new e-mail or reply to one that I have received I am able to type in all fields, but there is no "Send" button to the left of the "From", "To", and "Subject" fields.

I can work around this by clicking "File...Send Now", but that is very inconvenient when I am sending many e-mails.

I use Thunderbird to access my Gmail accounts. Gmail is confirgured for IMAP and I am able to access all of my E-mail accounts ... so that is good.

However, I do have one issue: When I delete an E-mail in Thunderbird, it moves to the TRASH folder and I empty that daily. However, when I go to Gmail, I can see that they are STILL in "All Mail". If I access All Mail in Thunderbird and delete messages, they reappear.

The only way I am able to get rid of them for good is to access them in Gmail. If I don;t, the All MAil folders grow like crazy and messages thgat I deleted are still there .. some were several years old.

Question: Is there a way to set up Thunderbird so that when an E-mail is deleted in Thunderbird, that it takes it out of "All Mail"?

I'm trying to add a Roadrunner email account to a new instance of Thunderbird (I bought a new computer).

The Roadrunner account already exists in my Thunderbird account and on the previous instance of Thunderbird.

When I attempt to add the Roadrunner account, Thunderbird rejects the Roadrunner account's password. Note that I can use the password get into the account on the Roadrunner site, but Thunderbird won't accept it. Of course,

Thunderbird's error message is vague to the point of being worthless, so I don't know why the Roadrunner account is being rejected.

What am I doing wrong?

My wife has been using Thunderbird successfully for many years (and we also donate to Mozilla from time to time) - she's been using her email account ([edited] @frontier.com) for at least 15 years, even after it was transferred over to the Yahoo email server a couple of years ago. Also, she has Windows 11.

Just in the last week, she has experienced serious problems (messages duplicating themselves over & over, & then not being to get any more new email at all (last email she got was on June 28th).

We've upgraded to the latest version of Thunderbird, & I even completely uninstalled & re-installed Thunderbird. I'm at the end of my knowledge & tried everything I know. I'd even be willing to pay for someone's services if we can get these problems fixed.

Thanks in advance - my name is Peter Ryall (cell #[edited]) and my email is [edited] @gmail.com, since she's not able to get new email right now.

I've done it before using ctrl-A and Print and got the date, sender and their address, and the subject line (I think in a csv file). I've since changed from Windows 10 to 11 and can't remember what I printed to. Trying it now and printing to PDF yields only the first entire message, but I don't want the message, I just want the sender (and date).

I hope you all are well!

I´ve been having a problem with thunderbird for a while now and today took the time to do the troubleshoot and checked all the account settings. no firewall, no add ons Researching the problem i came across the incompability of different TLS standards. Apparently when thunderbird updated to 78.0 in 2020 a lot of people had the same problem and solved it by downgrading . Since this problem came on suddenly, possibly when thunderbird upgraded automatically, and it only applys to select emails (about half) I guess different TLS standards, some of which are no longer supported by thunderbird, are the reason for this. If i log in to my mailaccount I can see all the emails, same goes for my mobile devices. That´s how i know thunderbird doesn´t display all the messages. My question: Did anyone else encounter this problem? Did I analize this correctly or did I overlook something? I don´t want to change to another provider. I always liked thunderbird for being simple and clean. But downgrading won´t be a sustainable solution either I guess. Thanx for your help. Have a nice day.

I use Thunderbird with my Jubii mail and lately, every time I try to send an email, Thunderbird wants my password to my email address in order to send he mail. How do I make it so that I won't have to reenter my password every time I send an email?

I was forced to change email from Comcast to Yahoo Mail and hate it. Downloaded Thunderbird and connected my gmail address, but it won't accept my Comcast address, which I use on Yahoo Mail.

- 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.

Put up a message regarding support to resolve issue with Thunderbird this morning. Cannot see the message or if any answers? Query was ref downloading email & history to Thunderbird while moving to another server provider (Gandi) and all history now missing.

After reinstalling a Windstream.net email account I continue to have Authentication Required errors at startup. Popup messages only occurs during thunderbird startup. And Only on my Windstream.net email accounts. not my outlook.com and Gmail accounts.

the following is the popup window during Thunderbird startup.

"Authentication Required - Mozila Thunderbird https://imap.windstream.net is requesting your username and password."

I entered the username and password and check the save box. The popup returns with the same error asking for the same info. If I just select CANCEL, it pops up 2 more times and after the third cancel, the popup shows no more. The account fills with any incoming emails from Windstream.net. The Windstream.net account seams to work normal from that point on. I Can send and receive fine with no more popups. Until I restart thunderbird then this error starts all over. Is this a thunderbird or Windstream.net issue? Any suggestions on a fix? Also I have a gmail and outlook.com account with no issues.

Certain messages in my inbox have the correct header in the actual message, but the wrong sender in the message list - see image.

I've tried repairing the folder, but it makes no difference. Webmail has the correct sender in its message list.

We have a common email address manger@redwoodscholars.uk we recently changed manager George left us and Louise joined us. Louise changed Georges name in the setting page and removed his signature on her laptop. I changed the name in my address book and deleted all my history, Louise sent me an email which showed it was from Louise<manager@ etc> BUT when I clicked on reply, the reply was addressed to George<manager@etc> The mail is managed by web mail on stmp.host.co.uk.

What else do I need to do to correct this?

Something has gone wrong with Thunderbird. My AOL account has stopped working with it.

My AOL account works fine via the AOL website, but Thunderbird cannot access it now.

My AOL account worked fine for many years with Thunderbird until just the other day.

Now I get this window (see image) and it does not allow to Sign-In.

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?
