System specs below. Thunderbird is set with 1 account: A paid Yahoo email, with a LOT of messages (well over 36K), using IMAP (Yahoo only lets the most recent 10K come down via IMAP, sadly). Most emails do download and are correctly rendered. But around 10%, starting usually a month or so back from the high water mark of last update, show email source code (text of headers, mimeparts, etc.) for a totally different email than the one highlighted (a few days later, different sender, etc.) Checking the message on Yahoo, it renders correctly. There is no pattern to the corrupted messages: they can be from mailing lists, company marketing mails, an alert from my local town, whatever.

Once the error occurs, it is consistent across Thunderbird shut-and-restarts (still showing same wrong email source as before). Emails to either side (earlier and later) render properly in the message pane.

Double Clicking the message to it's own child pane renders a pane with Subject and From as blank, and the same email source text for a different email. Forwarding the email puts the email source code in as text (I was hoping the act of refreshing and reformatting might grab the correct content, but no).

Doing a Repair Mailbox (which seems to mean "download headers again, then download all the mail again" does seem to correct for a time (including the previously corrupted emails now rendering correctly)... but within a day or two, a new crop of messages will be corrupted, and the dance starts again.

Windows 10, 64 bit. Norton 360 set to exclude all mailbox directories. Thunderbird 115.12.2 (64-bit), though this has been happening since 110. No plugins, no extensions.

Are there diagnostic logs or other info I can share that can help us figure this out? I really like Thunderbird, but it's just unusable here. Outlook, Apple mail, other tools don't seem to have this problem.

Once again, since my husband suddenly passed 13 December 2024, I cannot send or receive email via my intoknow.com account.

Previously, it was somehow "repaired." Please, i need this account to stay active.

First off you should warn that this version changes your profile, so there is no going back. I installed it and have lost ALL of my accounts and had to start from scratch. It took me back to the beginning. I hate the interface, too cluttered, to busy and generally sucks. I am thinking of dumping thunderbird at many, many years of using it.

This is a very strange issue. Some of the messages in my inbox, when selected do not display the message itself. Blank box. I looked at the message source and there is nothing displayed but white space in the box. The messages that are not displaying are before 3 August 24 and back in time to the year 2018. Those messages received in 2018 appear correctly.

Messages received after midnight (12:01 AM) 3 August display fine. Message source view displays the contents.

On that computer, I have other email accounts that display the messages correctly. Nothing missing. So whatever happened, only one email address account was affected. It is like something deleted that data.

Running Windows 10 Pro and latest version of Thunderbird. No extensions

Anyone that can inform me as to what might have caused this and tell me if it can be fixed, I would be greatly appreciative.

Thank you

I am a bit confused!

If I compose a message and start typing in the address field ("Partington") then 2 addresses are shown. One is the right one and one is an old one that I do not want.

However, if I look in my Address Book and select "All Address Books" then the old address is not shown. Can anyone suggest where it is picking this up from?

after i have suddenly upgrade to newest version my autocount can't send the mail by mapi system integration in software. i use that program is inside autocount called 'send by email (Ms Outlook compatible)'.

it appear error msg failed to send msg.

how i can solve it.i have try downgraded to old version and set default apps in default apps windows also can't.

thunderbird 115.13.0 how do i see my all folders with ALL of the emails? When i go to unified folders sent/inbox it flips the most recent email to the bottom, how do i flip it back, are there any videos, anywhere, that i could watch and learn from????? i can save us both a lot of tme if i could watch a video on how to do this? thank you...b³

for example: also how do i make a directed screen shot of a page? as opposed to the whole page?

I gathered all my mailboxes under Thunderbird and saved my passwords. All of them work except my Outlook email addresses (live) because I have to re-enter the password several times (inaccessible server message). Can you help me

For some silly reason when I changed my email password Thunderbird cannot connect to server either setup password or user incorrect. I am so sad because I love Thunderbird. I have tried everything I can think of. I chatted with Optimum and they said I needed to contact you. When I try to ping my server it just times out. My servers are pop.suddenlink.net and smtp.suddenlink.net. what could be wrong?

Would it be possible to reduce the size of files generated? Perhaps by splitting them into smaller files.

As a home user with a not very fast upload (~10Mb/s) it takes a very long time to transfer files to my cloud backup provider.

I really hope this is not intended because your software just updated itself to this new version, without even checking with me first. So if it did this on purpose, without checking if I wanted this first, that is pretty messed up.

See the attached screenshot. The light theme shot is from your main download page that shows how my cards are supposed to look, and how they USED to look before this update.

The dark screenshot on the right is now my message cards look now. They are OBNOXIOUSLY HUGE FOR NO REASON. They take up way to much sense and are physically causing me PAIN to have to visually parse.

I cannot stress enough, how much this change is affecting me. I am IRATE over this.

Please. For the love of GOD. Tell me there is a way to either fix this, or easily revert to my previous version. I am not on-board with this change at all and I will 100% go postal if I have to be stuck with this shit. I checked every nook and cranny and cannot find a way to adjust this, and from what I can tell, downgrading is neigh impossible.

I have switched to a new internet provider and have set up new Thunderbird POP accounts with the new provider. I have not yet canceled the old internet provider; both are currently active. The attached screen shot shows four accounts. The first two are for the older provider and the second two are for the new provider. All four accounts are POP.

Q1: Are the local folders that you see associated only with the old provider?

Q2: If I delete the old accounts, will all the emails disappear from the local folders?

Q3: If yes, how do I create a new set of local folders associated with the new accounts? I don't see an option to recreate "Local Folders."

Thanks for your help!

I accidentally deleted an email account through Tools- Account Settings - Account Actions - Remove Account.

Is it possible to restore this account and its associated sub-folders.

I have installed Thunderbird on a separate PC and restored my latest backup, which unfortunately is 4 months old, meaning that I am missing 4 months worth of emails.

Might it be possible to link to files/folders containing my messages prior to the removal, perhaps by recreating the email account or might there be some other method in which I could achieve this.

Any thoughts you might have would be VERY welcome.

Kind regards - Deirdre

Dear Thunderbird Support Team,

I hope this message finds you well. I am writing to seek assistance with an issue I am encountering in Thunderbird. Specifically, I am not receiving invitation links sent to my email address from Groove. Despite checking my spam/junk folder and ensuring that my email address is correct, the invitation does not appear in my inbox.

Could you please help me understand why this might be happening and provide any suggestions to resolve this issue?

Thank you for your support.

Best regards, Francesca

I have check my server details and all are correct, the same with the recipient email address. I have contacted my host and they have got me to try webmail which is all working fine. Does anyone know how I can fix this?

The email program my ISP uses is Zimbra.

I want to copy the various email folders with its email messages that were set up previously to Thunderbird.

How do I do this? The ISP advises they are not familiar with Thunderbird and cannot help.
