Three horizontal line menu bar is missing. All I have on top are three dots. … Home icon is also missing. Can’t find any way to fix this. Deleted the app reinstalled and still have the same problem.

I have just started getting this error message when sending email from my @live.ca account. I do not get this message when sending from a @gmail or @company.ca address.

Quote: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Non-Compliant sender address. Code : -1. Please check the message and try again."

I can send and receive email using this address from my Android phone or from my Windows eMail client, so why is Thunderbird causing this? I have looked through all the setting and cannot find anything different from the settings for the @gmail accounts.

Thanks. Dave

When I try to open "Inbox" on one of my accounts, I get an error message:

Unable to open the summary file for Inbox on jonathandsalk@gmail.com. Perhaps there was an error on disk, or the full path is too long.

I have tried right-clicking, going to Properties, General Information. But there is no option to "Repair folder"

Can anyone please help?

In Draft area, when I ask to save the item, it disappears every time and I can not find it anywhere. The same thing happens on another email account on a different computer. I am unhappy.

i have always used thunderbird and am now up to 64 bit thunderbird 144.0.1 on windows 11 25h2

everytime i am sent a pdf file as an attachment i'm having to get thunderbird to open the file before i can actually save it to disc

everything else, while asking me for a name & location to save the file simply doesn't

btw thunderbird is now configured to ask me what to do with the pdf file and it ALWAYS behaves the same

i don't want to have to open files like pdf's that may not be safe / virus free before being able to handle them

way passed the time you fixed this stupidity terry

My anti-virus reports that 30 to 100 times per day, it blocks firefox.exe attempts to establish a connection relying on an expired certificate to to www.temu.com. Can you please stop your attempts ? Or tell me how to stop them ?

Hi,

Today I installed Thunderbird to backup my Gmail account because I am getting warnings that my gmail account is running out of space. Everything seemed to work flawlessly. Until several hours later when checking my Gmail on my phone, I realized that I had not received any messages, which is odd. Then when I got home, I see on my laptop that Thunderbird had been receiving my gmails just fine. How do I get both Gmail and Thunderbird to receive new messages as I am often away from my laptop and need to check my Gmail on my phone.

Thanks,

From Microsoft: "Recent Outlook Mobile updates introduced a stricter and more standards-aligned S/MIME message structure. The messages themselves are valid, but some third‑party mail clients such as Thunderbird do not fully support the way Outlook mobile structures the encryption. As a result, these clients may display a blank message body even though the encrypted content is present.

As a workaround, if you need to send encrypted mail to recipients who use third‑party clients, use Outlook desktop or Outlook on the web instead of Outlook mobile. These versions generate encrypted messages in a format that is more widely supported. "

I couldn't find this reported anywhere in these forums. Is there a solution being worked on to address this issue? Or has anyone found a workaround? We are stuck with using the Outlook app until the Thunderbird app supports S/MIME.

I have recently switched computers, and since it has been a while, I can't remember the setting on the 'about:config' page that I need to change to where when I open a new browser tab, it opens at the end of my list of tabs, rather than as the next tab. Thanks!

There is an old question just like this here and the answer doesn't work for me.

I would like to see my tasks appear on my calendar ie a task due on the 26th should show up alongside any appointments I have in that date slot. Google Calendar does this.

The answer to the question linked to above says to use View - Calendar - Current View - Tasks in view

I have those options and I tried them. Nothing. I have a task with a date and time on it and I am looking in the calendar for the right date and I don't see it. Is this feature still working? Is there something else I need to do to turn it on?

Thanks

Hello to everyone.

I hope I'm able to describe my frustrating situation.

It has to do with online buying via Internet combined with a transaction confirmation over my Banking app. The problem occurs when I try to book or buy anything with the use of my banking Visa card. After I filled every field necessary and proceed the transaction, the process "secure by Visa" starts, where I have to commit, that I am the proper owner of the card. Concrete: I receive a message from my banking app where I have to confirm the transaction. After I confirmed it and the return to Firefox, the page reloads and everything I did before is gone... means: no buy, no booking was made... This can be repeated until the end of days without any success. The bank is not able to help me. According to them, everything work fine with any client.

One question for the start of the discussion... why is the page loading, why the page doesn't stay "stable" until I return from the banking app?

Thank you for your help.

For the last month I have been unable to send outgoing messages from my Thunderbird program. Initially I also stopped receiving messages, but a local commputer technician helped resolve that. I can now receive messages but, if I try to send an email I still get this message: "Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: p-impout003.msg-pkvw.co.charter.net cmsmtp 68.235.43.158 blocked. Please see https:// www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1120." I have tried to resolve this through Spectrum and was told I would have to go to Thunderbird Support.

I'm getting used to using Thunderbird but I can't enable spell checking. I've gone to settings and then composition and selected the "as you type" option but this has not enabled the spellcheck.

Can anyone help, please?

I bought a Windows 11 computer that I am transitioning from a Windows 10 computer. I like to start out with a clean slate and install from scratch. I exported my feeds into a.oplm file from the Windows 10 Computer. Opening up the .oplm file is see text as "xmlUrl="https://feed.podbean.com/potcast name/feed.xml". Is that the url entry that I used to enter in the URL for the feed if I manually subscribe to a Thunderbird RSS feed?

I would like to know, if there is a reason that the Thunderbird Flatpak still remains on a version published on July 7. Iam switching back to Thunderbird, because of the new Microsoft Exchange Feature.

Is there a Timeline for how the Flatpak updates are delayed or anything that can be done to push the current version into Flathub?

Hello Everyone,

Background: Using Thunderbird for almost an year and extremely happy with the product set. I use it to access GMAIL via POP and use the settings "After the email gets downloaded to my computer, delete the GMAIL copy" (Settings attached).

My usage pattern which changed recently: Earlier, I will always download emails using Thunderbird every day and it was working perfectly. Recently I have to travel for few days and during those days I will access my GMAIL via my android mobile primarily and I download all the emails after my return.

Current Issue: Now after I return, all the mails gets downloaded, but it does not get deleted at GMail side (online). From the time I started using Thunderbird after my return, the newer emails from that time are getting downloaded and deleted but the old emails stay in GMail. Current inconvenience is it takes time to validate if all the important emails are downloaded and I cleanup the GMAIL manually and then we are all in sync. This continues until my next travel. I tried resetting the GMAIL POP settings and there is no improvement.

Any pointers or suggestions to resolve will be gladly appreciated. Thanks in advance!

It very important to me to be abler to Turn OFF Dark mode when a recent TB update defaulted to that mode.

Why? Because I have vision problems. So I run everything under Windows' "High Contrast" mode, which changes all displayed colors and backgrounds.

Given that is how my system is set,  Windows "flips" your new Dark Mode into a light and low contrast image that I cannot easily read. 

SO For users like me who must depend on Windows High Contrast settings, everything is fine as long as Thunderbird retains the option to TURN OFF DARK MODE. Please be sure to maintain this option Forever, or TB will become unusable to users like me.

Thank you.
