Thunderbird Support Forum

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)

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.

Using version 115.

After adding an online calendar (Remember the Milk task manager/todo list), Thunderbird locks up. Nothing works. I've uninstalled/reinstalled the app with no solution to the problem. Windows' Task Manager shows Thunderbird using an awful lot of CPU resources and the amount does not seem to decrease, even if I leave everything alone. I don't know if this is one of those Lightning bugs I've read about but, whatever it is, Thunderbird is useless to me now. Suggestions?

I switches between my Linux and Mac Notebook once a day. Everytime i switch a specific email gets moved to the junk folder. Then i mark it as not junk. As long as i stay in this client everything is fine. When i switch the notebook the client on this system marks this email as junk again. When i mark it as non junk and switch to the other system this email gets marked as junk again.

How can i mark it on both as non junk so this behaviour described above does not happen again?

I have been experiencing slowness in Thunderbird, specifically with the loading of messages. It does not seem to be associated with IMAP or POP accounts or whether the messages have already been downloaded to TBird. Single messages load relatively quickly. The problem is most evident when loading any message found in a thread. It can take 5-10 seconds to load an individual message and much longer when that message is in a thread. The longer the thread the longer it takes to load. Troubleshooting such as clearing the cache and turning off extensions have not resolved the issue either. What is odd is that if I use an extension to view the threads, such as Thunderbird Conversations, there is no lag. Any thoughts on how to correct this issue?

Hi.

Since a recent update of Thunderbird 115.8 under ubuntu 22.04, the Calendar App “Lightning” has developed an error. When creating a New Message, the top 5 lines are missing - i.e the “End: (U)” (end time) line is displayed at the top of the screen. The only way to enter the Title of the Event is to drag the window down. Please see attached which shows the top 5 lines not displayed. Is there any way to fix this ?

Thanks, M....

Emails are being downloaded at a snails pace and never completes them, and all of a sudden last few days, continues to try to download thousands of emails. In order to do my work, I have to disconnect from Internet. Very frustrating during tax season. Can you help?I have already had my Tech guy take a look. It did not help.

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.

After entering Safe Mode to troubleshoot the hyperlink issue, 2 of 3 email accounts were deleted. After reinstalling them there are so many issues to report.

The most annoying is when replying to a message in a Folder under Local Folders no From account is selected, and no Subject until I remove the "re:" and it won't send until I save it as a draft, then edit and then it will send.

Emails work normally when replying if they are not in a Local Folder.

Several other issues but I'll start there. I've been using Thunderbird for many decades and have not had these issues before.

Thanks,

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.

Not sure why the computer will delete several sentences when trying to add a word or coma to the sentence. At times whole paragraphs have disappeared. Please help because we have lost important information.

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.

Details: 115.7.0 (64-Bit) (happened with older versions as well) 2019 16" MacBook Pro 2,3 GHz 8 Core i9 32GB Memory 1TB Storage macOS Sonoma 14.3.1 (happened with Ventura as well)

Twice withing the past 4/5 days I have (purely by chance) noticed an email - for which I had been waiting - on the list of five messages. (bottom right corner) waiting to be added to my inbox. When I went to read the messages only four new ones were there - the one I was waiting for, seen on the 'about to be downloaded' list - was missing. My wife informed me that she had experience a similar problem, eventually solved by locating the email furthe back in history, now attached to another email, and identified by some unexplained arrows. I went in search of similar arrows and found my missing email now attached to an earlier title.

What on earth is the purpose of this? If I hadn't spotted the email as I did and as it didn't appear as a recent addition in the inbox, I could not have known it had been sent to me. After the glimpse l'd had of if I emailed the sender to check that he'd sent it. He was puzzled as to why I hadn't replied.

I'm a long way from being an expert - scarcely competent in fact - in computing matters, but I am capable of filing my own mail. Please can Thunderbird leave it to me in future?

When I attempt to retrieve mail (from some accounts) I receive the error message "account being processed, please wait until completion to download the messages" (see att.). Even after a long time (hours) the same happens - so I have to use my phone or IMAPS to get my messages. This happens only since I upgraded to Supernova (currently 115.7.0) and apparently on mail server orange.fr (but not all my mail accounts on orange.fr). I did not change (manually) any setting. Other mail servers (including wanadoo.fr which is an orange.fr mail server) seem to work ok. Thanks for any help & BR Max.

Hello. I can't send a message, the settings are correct. The hoster checked the data, everything is working for him. For some reason the program refuses to work, what should I do?

Here's the error:

Error sending message. Error sending mail: Outgoing mail server (SMTP) error. The server responded: Cannot connect to SMTP server ip (ip), connect error 10060.

Hello,

i have an issue with my email, i have made no changes but from today, my thunderbird takes very long time to open. In bottom taskbar it says building summary file for the inbox.. and it takes about 5minute to load inbox list, "26000 letters." Also i can send but cannot receive any letters and i am missing last 3 months inbox mail.

How can i try to solve this issue without causing more damage or loss.

Thank you.
