Hello, I would like to know how the retention policy effects sub-folders. Does the Retention Policy (RP) propagate down to sub-folders?

Example: I create a folder in my EM account, call it folder1. I go into the RP tab and un-check the use global settings and choose never delete EM's. I then create folder2 as a sub-folder of folder1 and create a RP, un-check use global settings and select delete EM's older than "x" days.

Will folder1's RP take president over folder2's RP and never delete EM's or will folder2's RP override folder1's RP and delete EM's older than "x" days according to folder2's RP?

My OS is Linux Mint 22.1 Cinnamon, Cinnamon Ver. 6.4.6 Thunderbird-Nebula 128.7, 64Bit for Linux Mint-001 - 1.0

Thank you, MA

Hello! And THANK YOU!! As you can gather from the subject line, I want to know if Thunderbird can be loaded automatically upon booting my computer?

My OS is Linux Mint 22.1 Cinnamon, Cinnamon Ver. 6.4.6 Thunderbird-Nebula 128.7, 64Bit for Linux Mint-001 - 1.0

I also have a master password enabled on my TB installation.

If not, maybe it could be added to a future release:)

Thanks again, MA

I bought a new computer and had to download Thunderbird again. I tried the most recent one, didn't like it, so randomly picked a previous release from 2023 (don't remember when I installed the previous one) and hoped for the best. In the past, I would keep some emails in my inbox and tend to them as needed and then keep or delete when I had done what was required. I would also need to go to my ISP email's page, to get spam email, because Thunderbird didn't provide me with those. When there, I would delete what was in the inbox, so I could easily keep letters there to a minimum. Now, however, when I delete something in my ISP's inbox, it deletes in my Thunderbird portal too. I can't find settings in my ISP's page to stop it from downloading automatically (so it won't duplicate what I've already received via Thunderbird), and I can't find any settings in Thunderbird, to ask it to keep what I have in my inbox, instead of deleting everything I delete with my ISP. Do I need to go further back and find an earlier release in order to be able to use Thunderbird as I used to do? Or can I tweak the one I have?

I'm running Thunderbird on Mac OS 15.3. I have two POP accounts in Thunderbird; the configuration has been stable for years. This evening, I went to add a new account, and Thunderbird seemed to have decided to update itself, including flipping me over to Chrome where it opened a page about Supernova.

Thunderbird relaunched and came up with an empty "Chat" window. My usual mail window is gone -- and I can't get it back. I can't get an "About Thunderbird" window to open.

I actually can't figure out what happened. My mail appears to be gone. My accounts seem to be gone. I can't open Settings, I can't open Account Settings.

Wait, the mail accounts seem to still exist -- I can tell Thunderbird to check mail, and the POP server shows the checks happening -- but if I send mail to myself, nothing opens. Also, all of the Layout menu options are greyed out.

Help? :-)

Thanks, Vince

How can I tell Thunderbird to return false positive "junk" e-mails to their original folders?

My e-mail-server was moved to another provider. I set up a new IMAP account in Thunderbird 128.7.0esr. It downloaded my emails and falsely marked 7,298 (seven thousand!) emails as "junk" and moved them to the relevant folder. 1 (one) email was correctly marked as junk.

I have marked all 7,298 messages as "not junk". However, they just sit there. They are not being returned to their original folders.

According to https://blog.thunderbird.net/2024/09/thunderbird-and-spam/ the should automatically return to their proper folders. But that is not happening.

That's a problem, as they are from many different folders. Inbox, Sent, Archives, group boxes, drafts, you name it.

What to do?

The title describes the problem. This is an old problem that seems to be triggered by something embedded in the email. Other emails print to PDF or the actual printer without a problem. For security reasons, I cannot attach the email in question as it involves money and account identification.

The email is a credit card reward certificate from Costco and generated by Citibank in case someone else has reported this specific problem.

Desktop PC running latest Thunderbird and Firefox. Started Thunderbird, instead of the usual tabs opening, it appears to have forgotten my accounts, asks for my email address, i.e. starting from scratch again. Starting Firefox, all previously-open tabs have gone, though bookmarks are all there.

Has there been some update which has wiped or reset Mozilla data? Yes, obviously I can go through setting up Thunderbird again but that will take quite some time and yes, I can use Firefox but many of the tabs I had open were there for a reason and it will take a while to find them all again.

Is there any way that the previous state can be recovered? My laptop has both applications running fine and I have paused Windows updates for a week, just in case the latest update caused this. Thank you.

Please tell me how I can remove this message. I have never seen it before and now I cannot read e-mails after 8/2/25 (I have been away for a few days).

I have tried to send myself a test message today but it will not go. I have tried cleaning out my mail server mailboxes but this has no effect. Running anti-virus software has no effect either.

Any help would be appreciated,

Thank you,

Tregarth

Bonjour, J'ai supprimé par méconnaissance le dossier "tous les messages" et j'ai perdu tous les messages dans mes dossiers ! Comment peut-on les récupérer ? D'avance merci pour votre aide.

Hi,

I'm searching for a possiblity to assign a task to a user, like it is possible for an event. According to RFC 5545 this should be possible for VTODO however in the GUI the "Attendee" field is missing. Is this an intended situation?

Regards

I use Thunderbird on two user IDs on the same Mac, which is running macOS 15.3.1.

I usually run Thunderbird updates on user 1, but this time I ran the it (to 128.7.0esr) on account 2, and I can no longer launch it on user 2. (Note: Neither user is an admin account.)

Steps: 1. On user 2, launch Thunderbird. 2. Get the dialog that there's an update to 128.7.0esr. 3. Click the Restart to update button. 4. Get the dialog that there's an update to 128.7.0esr. 5. Click the Restart to update button. 6. Get the dialog to enter admin ID and password for installing the Thunderbird helper. 7. Enter the admin ID and password and click OK. 8. Get a (surprise) dialog to authorize Thunderbird to discover my devices. 9. I choose to deny.

Expected result: Thunderbird relaunches, now with 128.7.0esr. Actual result: Get the dialog to enter admin ID and password for installing the Thunderbird helper.

10. Log off user 2 and log on to user 1. 11. Download 128.7.0esr from the Mozilla website. 12. Check the hash. 13. Install, choosing to replace the old Thunderbird in the shared Applications folder. 14. System Settings, About, System report, Applications 15. Verify the signature is signed by Mozilla 16. Launch Thunderbird

Expected and actual result: Thunderbird launches and I can use it normally.

17. Log out of user 1 and log into user 2. 18. Launch Thunderbird

Expected result: Thunderbird launches and I can use it normally. Actual result: Get the dialog to enter admin ID and password for installing the Thunderbird helper.

I'm guessing there's some manner of residual file that's preventing Thunderbird from launching on user 2. I've verified Thunderbird is in the system's Application folder and not in user 1's files.

How do I clear the pending install from user 2 so that Thunderbird will launch for user 2?

I believe I have it 90% setup correctly, but I still cannot get any outlook email to it. The folder shows up as: name@location.com

    Inbox

During the setup when I clicked on "Re-test", a green notice "The following settings were found..." Then I clicked on "Done" and I get a yellow notice "Unable to log in..." I repeated the "Re-test" and still, the green notice came up, clicked on "Done" and the yellow notice came up, as if it is in a endless loop.

Error message image (screenshot) defines the issue, how do I fix this?

I was never prompt for a password. Which is why no email was loaded for viewing. I am using 0Auth2 for password access. Thunderbird version 128.7.0esr (64-bit) Ubuntu version 24.04.2 LTS

Is there a "current" correct setup procedure that works, that I can use?

Hi I am having an issue with getting new contacts to add to a email group. It was working just fine and then, I couldn't add anymore new contacts. What is going on and how do I fix it? Sue

Emails in two of my inboxes (maybe all four) are randomly disappearing. None of my email templates are showing up in either of my two template folders. This started two days ago and I cannot figure it out. Emails get downloaded, then some are just vanish but are still on the servers. Repairing the folders does nothing, but folder properties on my template folders show the number of messages that should be there. Thanks in advance for any help you can provide.

Is there any way to get Thunderbird to show ICS files? Right now it just shows the contents as unusable trash in the email body.

Before anyone says it, toggling 'Display attachments inline' doesn't do anything. Enabling a calendar in Thunderbird allows the 'accept' etc buttons, but then I have to deal with the headache of a calendar in Thunderbird and still doesn't show the ICS file so I can use it with my actual calendar app.

When I create a calendar event, it will not show up in the calendar view (Month), even after trying several times. What I found is, it will only show up on the calendar if I uncheck the Notify Attendees box at the bottom, which is by default always checked. After I uncheck the Notify attendees box on an event, that event, and each successive event will then show up on the calendar, regardless if I have the Notify attendees box checked or unchecked. I looked to see if I can uncheck this box in Settings, but do not see where this can be done.

Is there a way to have the Notify attendees box unchecked by default when I create a new calendar event?

Hello, We have problem with sending and receiving e-mails. Sometimes Thunderbird just stops receiving e-mails. We can send messages but they can be saved only in local folder. In browser e-mails arrive and we can send them without any problems so it has to be some problem with Thunderbird. We were trying a lot of solutions, but only one works - creating new profile. It is very time-consuming solution, because we have to copy all e-mails, contacts, user settings, etc and we have to create a new profile couple times in a month... We were trying to off our antyvirus, forget password, etc. Probably there is some problem with certificates, but we do not know how to fix it. We use IMAP. Let me know what we can do to solve this problem, because creating new profiles is too tiring... :(
