Thunderbird Support Forum

I use Thunderbird 115.8.0 (64-bit) on Windows to check 10 email accounts all on the same server. The setup in Tbird for all accounts is identical. I only have a problem with one account.

The problem is that on one account, after a small number of replies on a thread, the Send button becomes greyed out and emails will not save.

The other email accounts continue to work just fine.

Compacting mailboxes does not fix the issue.

I don't know why this is happening or how to stop it. Today, for the second time in about 4 months, I opened Thunderbird to find that I'd been flooded with new copies of old emails. They were all marked unread, and I did a random sampling to see that all the ones I checked I already have a copy that has been marked as read, and for some of the older ones, has been archived. Today's influx consisted of 78 messages (it was about 150 messages the first time it happened) ranging in age from last week to June of 2022. I do not believe I have changed any account settings in the last 9 months, either within Thunderbird or at Gmail, where the account is hosted. In each case all the messages were confined to one specific folder--the first time it was the Inbox folder. This time it was a sub-folder named "Receipts". If I have someohow accidentally triggered this, I'd like to know what to change in order to prevent it from happening again.

A week or so ago I patched Thunderbird (115.8.0 (64-bit)). Everything seemed fine and I proceeded to empty the TRASH. It took an unusually long time to delete the roughly 175 messages in the TRASH. Then the screen "blinked" and when Thunderbird reappeared the SENT fold, while present, showed that it contained NO emails. I have sent about 50 emails since this occurred and the counter on the SENT folder continues to show the the folder contains no emails.

Does anyone have any suggestions as to how I can get things to work again?

Hello all,

I haven't opened my email-client Tunderbird since 13.07.2023. I've opened it today and due to automatic downloading with start, it downloaded nearyl 2200 emails.

But they don't appear in my inbox. I can't find them via search. Due to automatical deletion via smtp they're not in my email account anymore.

Can you please help fixing this issue?

When I have moved a message from Inbox to a folder, sometimes it disappears. It is not in Trash or any other folder. I am on Windows 11 and TBird Version Version 115.8.0 (64-bit)

I just updated to 115.8.0. I have a much older mac without the upgrade and it is not having the same problem as my os 12.6.3 mac. Some of my inbound emails from are being taken over by a particular email from another sender so the message displays as the other sender, as does the from and reply to, but the subject retains the info from the original sender. Three or four emails in a row will all look like the other sender. The other sender was a public radio station. What's going on?

For example, the email displayed below is from one of my vendors, and has a simple message saying Thanks. The subjct line referencing a quote is correct. The rest is not.

Thunderbird has worked flawlessly for my Outlook account as well as several IMAP accounts now for the last 2 days, it refuses to send. CY4PEPF0000EE36.mail.protection.outlook.com gave this error: Requested action not taken: mailbox unavailable (S2017062302).

Refuses to send ONLY from Outlook.

I haven't been able to access my Thunderbird email: smokneva@comcast.net on my computer for weeks as it's been blacklisted. Please correct this asap. Thank you, Eva Miller

Very often (probably 3/4 of the time) when attempting to move a message to a folder, nothing happens. I have to select another message then quickly go back to the message and quickly select Message Move and then scroll to the desired folder and hope it moves. Sometimes if I don't do the above steps within a few seconds, the action does not occur and I have to redo the above steps.

This happens more often with a message that has been selected for more than a few seconds.

I have kept Thunderbird updated thinking/hoping I wasn't the only one encountering this problem but it has persisted since a significant update in the 2 months or so.

Thank you.

This is the third time in 3-4 weeks that this has happened. When I detached an attachment, the entire email disappeared. It is gone and a search for it comes up empty - even the trash and junk folders. It is just gone. Message body is set to Original HTML. There were no other attachments in the "attachment" drop down. Version 115.7.0 (64-bit). Again, this has now happened three times and there is no way to retrieve the emails.

Every once in a while message attachments wont open. A temporaty fix is to fix the incoming folder but that takes a long time every time i have to do that.

This time i decided to check the error log and found this error:

NS_BASE_STREAM_CLOSED: Component returned failure code: 0x80470002 (NS_BASE_STREAM_CLOSED) [nsIInputStream.available] NetUtil.sys.mjs:445

I previously posted here about an issue where Thunderbird would display document icons instead of folders in the Favorite Folders view, and also put these icons at the top of the list, out of alphanumeric order. In the previous thread a fix was suggested...

...but that fix no longer works, and new folders on a brand-new installation of Thunderbird (with no previous profiles on this system) now exhibit the same behavior.

The Favorite Folders view should display folders using folder icons and in alphanumeric order. What steps can I take to ensure Thunderbird does so?

This is on 115.7.0 running on MacOS 14.3.1. Thanks.

My account is not sending or receiving emails. I have always had to enter a password to access my account and now it is open without a password. I am trying to access some important emails! I tried logging in through Yahoo and cannot access there either. It tells me it has sent me a code to my email! If I click on try a different method it tells me to try again later. Love that your site asks me to tick 'email me when someone answers'

Hi guys,

I have a weird problem with my thunderbird on my PC.

I really want the icon pinned on my taskbar but no matter what I do it keeps removing itself once I open thunderbird.

I tried all kind of things, creating a shorcut and pinning it instead of doing that from the start menu, pinning it from the start menu, from desktop, from the app .exe itself. Nothing, it keeps removing itself!

I don't have this problem on my other windows machine so I really don't know what to look at.

Thanks in advance,

Mauro.

Using Thunderbird 115.6.0 (64-bit) in Linux Mint MATE 21.3.

Settings|General|"Save files to is" not selected ("Always ask me where to save files" is.) "Desktop" is shown, greyed out.

Note that Settings|General, for Content Types mentioning PDF, the setting is to use Document Viewer (xreader).

Process:

1) Create new e-mail. 2) Add PDF attachment. 3) Double click on the attachment to view.

It opens in Firefox Web browser, instead of in the system's default Document Viewer.

This also creates an empty <random>.html.part file in the Desktop.

Note that viewing a PDF attachment in an incoming e-mail works fine.

It seems there are two problems: The PDF does not open in the Document Viewer, and an empty file is left behind.

The process used to work quite some time ago (many months, anyway) - not sure when.

Any ideas?

This happened both on my old install of macOS Ventura as well as a clean fresh install of macOS Sonoma: When I open Thunderbird, it beachballs (is unresponsive, shows macOS beachball, fan ramps up) for anywhere between 5-25 seconds. This only happens when an account is set up, if I delete the account, Thunderbird starts quickly again. This happens with accounts from different providers.
