Thunderbird Support Forum

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)

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.

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.

Thunderbird is often asking again to log into Gmail and Outlook accounts.

A few days ago the accounts I have were "disconnected" and a few days later, randomly some accounts ask me again to log in and allow access to email.

I have about 20 emails managed with Thunderbird and after a few versions (about 3-4 months) this problem started to happen.

Has anyone else reported something similar?

An observation is that I use MozBackup to make complete backups of emails (including login and password) and restore them after formatting the computer.

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?

After some moment thunderbird cant receive sended emails from server. Its downloading messages and after that, when im trying to open a blank message the new is arriving. I was trying to "repair" folder and also completely reintstall thunderbird - nothing changed. Could someone give an advise how to solve this?

Juno very suddenly refused to accept my password yesterday which is saved on the computer, so I cannot get to my email. Why would they do that and how can I get into email. I got the box that asks for a new password which I filled in, but the site still refused to accept it. Please send the answer to GrandmaDonnaPowell@gmail.com. Thank you.

Currently using MacOs Big Sur 11.7.10 and Thunderbird 115.6.1 and every time that I restart laptop or the Thunderbird app I have to re-enter the passwords for the email server accounts, sre-enter message filters, and Thunderbird preferences such as PDF reader for PDFs. Any suggestions most welcome.

I have tried to re-download previous versions that worked just fine, but I still receive an error message every time I access my email ["Login to server imap.secureserver.net with username ________ failed"]. I've updated my password multiple times but nothing seems to work. Any ideas on how to get this fixed since there is no customer service line to call?

Running TB 115.7.0 on an iMac. I've made no changes to any of the setting recently. Overnight it stopped being able to send messages. Instead I get this error message:

"Sending of the message failed. An error occurred while sending mail. The mail server responded: Requested action not taken: mailbox unavailable Sender address is not allowed.. Please verify that your email address is correct in your account settings and try again."

I have checked my email address in account settings and I have checked my SMTP settings and all seems to be correct. What could have caused this sudden change in TB's behavior and what can I do to fix it?

Thanks, Ted

I am able to still search and easy view my emails and their contents. However, if I attempt to open the email the contents of the email are gone and in accessible.

I need help fixing this issue as I am losing important correspondence.

I have an IO group account, and mail delivery from messages sent to/from them is erratic. Sometimes they arrive within seconds; other times it takes over a day. I know the messages are sent, because I can see them on the IO group, but not in my inbox. I don't seem to have issues with any other emails, only IO groups

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.

Hi there, I am having a problem with the latest version of Mozilla Thunderbird. When I try to print a message from the Sent folder, everything looks fine in the preview, but when I print it to my printer or even to PDF, then I have headers and the first 2 words from the mail, the next is the blank page (should be my message) and on the next page is the message I'm replying to.

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.
