Thunderbird: форум сообщества

I have 3 computers. Two are running Windows, and one is running Linux. I was pleasantly surprised to find that Linux Mint has Thunderbird built in. I keep the two Windows computers in sync with a file compare program, "Beyond Compare" Are my local folders compatible between the two operating systems so I can sync my Linux Thunderbird local folders with the ones I have stored in Windows Thunderbird local files?

Are txt files stored the same in both NTFS and ext4 systems?

I have this issue with my reminders for peoples' birthdays. I have an event on their birthday that comes from my Google contacts. That event has a reminder 1 week in advance. When the 1-week mark hits, I get an undismissable notification from Thunderbird. I can close the reminder window, but it'll show back up within a minute or two. I've tried removing and re-adding this calendar but it doesn't matter. When I look at the details for the event, I see that the Organizer field is Unknown Organizer <unknownorganizer@calendar.google.com>. My regular email address is listed as an attendee. This has been happening for at least the last several months, perhaps more than a year.

hi :-)

My Thunderbird uses between 19 and 34 GB of RAM. It's cyclical (with a period of about 10 minutes).

What do you suggest?

Do I need to perform a performance diagnostic? https://support.mozilla.org/en-US/kb/profiling-thunderbird-performance

Do I need to follow all the steps listed on https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems#Diagnosis_Steps, or can I skip some of them?

Hi!

I have configured a EWS email account that requires manual configuration (I need to pass the override Office365 settings with application ID, tenand ID,...). When I select manual config I can configure the EWS server settings OK and the receiving part works OK. The problem is the outgoing server is not created OK (it is imap with password setup). I need to use the same EWS to send the email, imap is not allowed in the account. And I cannot configure the account to use EWS as the outgoing server. The outgoing server cannot be EWS and I need to setup one. So I'm in a loop.

For what I have read, thunderbird can send the email using EWS (https://support.mozilla.org/en-US/kb/thunderbird-and-exchange), but my feeling is that using manual setup (which I need to do to configure this account) breaks something internally and the outgoing is separated from the EWS receiving part. And I cannot configure back to use the internal EWS configuration in the receiving server part.

Can I do something to send emails using the same EWS configuration? What does the automatic setup to use the EWS configuration? Is there any bug for this situation?

Thanks in advance!

Hi,

I used to scroll up in current message using Shift+Space, but it stopped working for a few days now. it's not mentionned in moving around TB, so I don't know if it was normal behaviour or a feature added by TB's arch maintainer.

Thunderbird 1 of 7 working Spectrum email accounts stopped retrieving email. Tried to setup the account on new computer and it will to connect to Spectrum's mail server. Able to setup the other 6 on new install Tried under windows and Linux same problem.

I have an email account that was establish 30 years ago that suddenly stop working in Thunderbird but it is accessible through Spectrum's web server.

Spectrum wants me to verify Thunderbird is not the problem. Sounds like passing the buck to me.

I need some help with this one.

I have set a custom theme on my Thunderbird on Linux. As you can see by the attached image though, the menu bar is hard to read when you get to the right side. Dark background and dark text doesn't really go together. Is there a way to make the background of the menu bars a solid color or something less see-through so the text can be read? I want a light theme, but I need to be able to read the menu.

This happens regardless of whether message is moved to trash or junk folder. My concern are this also marks spam, phishing and/or malicious emails read which allows read receipt to be sent when enabled. I don't want to be forced to use remove immediately or disable read receipt option to ensure these messages are deleted unread.

I have just installed Thunderbird on a replacement computer (running Linux Mint). The version I have is 140.7.1esr. I use a POP Gmail account. For a change it installed and connected seamlessly, but I cannot persuade it to download anything other than the messages in my Inbox. I have right clicked as recommended on my Gmail address, but see no 'Subscribe' to select. What am I doing wrong?

I've successfully connected to a hosted Exchange server through EWS and NTLM authentication (kudos BTW). But there is a problem - often during operations against EWS I'm presented with "Login to account XXX failed" "Login to server YYY with account XXX failed". I can ignore it (cancel) and it will work for seconds or minutes but eventually reappear. Sometimes it's very frequent, sometimes is here and there. TL;DR; connection works, I can read directories and e-mails.

From looking at development tools I see these scenarios: 1. POST requests return 200 always (no messsage of course) 2. Eventually a POST would return 401. Then Thunderbird issues a GET, it returns 401 as well but response includes header WWW-Authenticate: NTLM XXXXXX. Then another GET is issued containing header "Authorization" with the value from previous response. This time it gets 200 and continues without POST requests without a dialog. 3. Sometimes there are more POST requests with 401 (I assume in parallel) before a GET is issued and then I see a dialog. Sometimes it recovers (regardless of whether I cancel or retry), sometimes gets stuck with 401 with dialog reappearing each time it tries something. This case it's similar in sense that thunderbird issues GET with 401 and WWW-Authenticate header, issues another GET with Authenticate header but still gets 401.

If I had to guess I'd say the problem happens when POST requests are issued in parallel, not sequentially. OTOH it might be a problem at the server, but it isn't very likely.

Yesterday I found that I can't send mail using Yahoo.ca. I was able to get my wife's computer working by sending an email. A message came on the browser and I logged in to Yahoo. She can now send email. When I tried the same thing on my computer, I get a message "No apps available". I have spent hours trying and can't get around the message. The simplest test is as follows:

• create a new profile, and open the new profile
• enter my name and email address, and continue
• I get a message "Configuration found in Mozilla ISPDB." It uses SSL/TLS and Oauth2
• I hit next. Yahoo opens a page in my browser to log in. I enter the password and the security code sent by text
• The browser sends a message to allow an app. When I allow it the message "No apps available" appears as shown.

The release notes on Thunderbird are Version 153.0 | Released July 21, 2026 For now, I can use a second account on gmx.com to send mail, but prefer to use Yahoo when it works. Any suggestions?

Dear Foristi, after updating to V. 135 Oesr (64Bit), neither AOL mail nor Yahoo mail cooperate any longer. Passwords checked, correct. Other PC, not updated, still connects to AOL and Yahoo addresses without flaw. OS: Linux Mint, both PC have 8 GB RAM. Where did I screw up?

Thanxalot in advance -rick

Linux Mint 22.3, Cinnamon Thunderbird 153.0 esr

clicking on 'get messages' produces no response. zero. Nothing happens. two email accounts are affected.

Consistently Reproducible.
