Thunderbird Support Forum

I have been using Thunderbird for several years for my GMail accounts, and have always preferred to download my messages using the POP and SMTP protocols, rather than use the IMAP protocol which leaves them all on the web. Google now inform me that "To help keep your account secure, Google will no longer support the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password. Instead, you’ll need to sign in using Sign in with Google or other more secure technologies, like OAuth 2.0. What do you need to do? Email software, like Outlook 2016 or earlier, has less secure access to your Gmail. Switch to Office 365, Outlook 2019 or newer, or any other email software where you can sign in using Sign in with Google." These changes are due to take effect from May 30th. How can I prepare for them and still use the POP and SMTP protocols after that date? Is OAuth 2.0 appropriate?

Most of my emails suddenly got erased from the server (I checked in cpanel). Thankfully i took backup few days back, and thunderbird still has them saved offline (Not POP3, its still IMAP configured). I recovered most of emails but those are visible only on my system. How can i put back those emails back into server, so it can be accessed from other devices as well?

Hello! Using Thunderbird for some years now and very happy normally. Although after trying to send 1 email with a special character "å" in the address, that did NOT succeed, now everytime Thunderbid launches, it pops a dialogbox:

Dialogbox [Unsent Messages] [X Close] Do you want to send your unsent messages now? [Checkbox, Checked] Always ask me when I go online [Send Now] [Later]

Everytime I launch Thunderbird, it now welcomes me with the dialog box!

I have ZERO messages in [Outbox] folder and [Queue] folders. (Is the latter an official Thunderbid folder?) Both are empty. I have repaired ALL folders. I'm always online.

The email was never sent away, probably due to impossible character in email address, and I never saw the unsent email so I have not been able to delete it. Clicking the [Later] button dismisses the windows but then brings the problem back in the future.

Where is the list of log or index of unsent and still to be sent emails? Apparently Thunderbird knows something, despite [Outbox] folder being completely empty!?

I've manually gone offline and back online and sayed online like normally.

PS. read this topic which did not solve my problem! https://support.mozilla.org/en-US/questions/1072963

Any and all help is welcome. Thanks

My email address and password were hacked today, so I can't get access to Thunderbird. I contacted my Webmail provider (Telstra - Australia) who have issued a new password that works in Webmail. However, apparently TB is only updated(?) once a month, and until then, my password isn't recognised by TB, so I can't get access to send and receive emails. I hope that makes sense. My questions are: is it true that I may have to wait up to 1 month to get this sorted; if an update is needed, when is the next date this will be done by TB; and is there any way that I can get my password sorted before the next update.

A probably related issue is that my Instagram account was hacked about 3 days ago and I got a scam email saying that my laptop had been accessed.

Thanks, Graham

Every day I notice this message pop up on the status line of TB. It's always the exact same message, compacting saved 1.5GB. Now, I'm pretty sure that I don't actually get 1.5GB of space savings every day, so why does this keep popping up?

My TB is running the current version.

I am running TB 91.7 in Win 10, with Bitdefender AV and firewall. When attempting to send an email, I received a popup indicating an issue with the SMTP outgoing server. (original message attached) (also original in and outgoing server settings attached). Upon checking the ISP's recommended settings, I discovered some updates (settings attached) and made those to TB (settings attached); I had to do some interpretation here, hopefully correctly. Attempted resend of message, still error messages (two popups attached). The webmail version works fine. Thanks.

I set Thunderbird up for the first time earlier today and wrongly opted for POP. I realise now that it means I can't see my Sent folder, etc, so I'd like to change to IMAP. Unfortunately the article explaining how to do this on your website does not relate to the newest version of Thunderbird, as installed today. I've tried deleting the programme and reinstalling but it's remembering that I chose POP and not letting me start with a clean slate. Please can you help me with this, as I'd love to use Thunderbird!

I have a friend whose G5 Mac Tower is running OS X 10.4 / System 9 and he needs to install ThunderBird.

ALL Of the System requirements for releases prior to 31 are missing. https://www.thunderbird.net/en-US/thunderbird/31.1.0/system-requirements/ None earlier than THAT.

Which Version of Thunderbird runs under Mac OS 10.4 ?

This issue shows up randomly, affecting a random number of messages. Issue is that one message will take over other messages following. Message notification will look normal in the inbox, but click on the message following X message, and the X message is what will appear. The subject line at the very top of the page will be from Y, but the rest of the information following will be from X. Two, three or more messages may be affected. Deleting X will make no difference. This time, four messages were affected.

After installing the latest update 91.0.9 (I think), TB starts, shows my 'folders' in the left column and 'event's in the right column, then, instead of showing the selected email folder, an hourglass appears for a few seconds and then nothing. I've sent multiple crash reports. I tried uninstalling and re-installing to no avail. I've used TB for 10+ years on both PC n MAC - first time it's left me high and dry. HELP !!

Is there an add-on for Thunderbird version 91 for importing emails from Windows Live Mail?

I tried "importexporttools-3.3.2" and it says it is has been corrupted, and besides it says it is for Thunderbird 14.0 - 60.

Thanks Murray

I have two email accounts. On the first one I cannot send or receive emails. I get message "login in to server imap.telstra.com with username *******@bigpond.net.au failed."

On the second I am receiving and sending emails but it is not saving my sent emails.

Any suggestions?

Hallo, i've updated my Thunderbird to 91.8.1 on my Kubuntu 18.04 Lini9x machine. I have some *.ics files attached as calendars via ftp (ftp://192.168.1.1/Kalender/xxx.ics). After the update Thunderbird/Lightning tries to open them in firefox.

Every time Thunderbird/Lightning syncronises the calendars, different tabs occur in Firefox trying to open the files. Thanks a lot in advance, Gruß

I am having difficult connecting to mailboxes in Plesk Obsidian on a VPS. I can set up the mailboxes in Plesk and make a note of the password. I then go into TB and start the 'Add Mail Account' process. All goes well at first. I get a green message saying 'Configuration found by trying common server names' (automatic connection). When I click 'Done' TB whirrs for a bit and then comes back with a green message showing a tick and 'Checking Password' but an orange message saying 'Unable to log in at server. Probably wrong configuration, username or password'. If I try manual configuration I get a similar sequence (using ports 995 and 465, SSL/TLS and 'Normal password').

I do not have this problem when working with cPanel (on a different server, but very similar mailboxes and security settings). This suggests to me that there's something amiss in my Plesk settings, but what could it be?

I have searched around without success. Most articles that might help are for TB 31 (even the Plesk Obsidian on-line manual). Any suggestions, please?

When I reply to an e-mail using Thunderbird, quoted text appears (in Thunderbird) with a quote bar on the left as expected.

However, when the recipient gets the message in Outlook or GMail, the quote bars are missing. In GMail quoted text is indented and a slightly different color (though it's hard to see the difference). In Outlook the quoted text is just indented.

How do I get Thunderbird to include quote bars for quoted text in the sent message?

If I format the message (with quote bars) using markdown in a browser, and then cut/paste the formatted message into Thunderbird, then it appears as expected to recipients using Outlook and GMail. But that's a painful way to compose replies to Outlook and GMail users (IOW everybody I reply to).

I'm using Thunderbird for gmail in IMAP mode. In my IMAP folder, I have a Junk subfolder, and in my Gmail subfolder I have a Spam subfolder. What is the difference between these? Does Gmail determine Spam, and Thunderbird determine Junk? Are BOTH Spam and Junk used for the Thunderbird adaptive junk filter log?

I am getting daily phishing emails from .gmail where there are obviously no Google controls to prevent. How can I block the entire domain in Thunderbird? Thanks

In the email client I have just come from the Unread folder contains all unread messages irrespective of the folder they might be in. The Unread filter in Thunderbird appears to relate only to the highlighted folder. I have many folders, the list being long not all are visible on the 'home' view. This means that messages in folders far down the list are only visible if I scroll down looking for them. Is there a way to modify the Unread filter to ensure that all folders are searched for unread messages and displayed together? I am using TB 91.8.1.

Hi,

I, like a gjillion other people, received a notice from Google/gmail saying I'm likely to lose access through Thunderbird unless ... blah blah.

I was running TB v59. If stuff works I don't make changes. It makes life simpler. I did a heap of online reading and research about this and found lots of advice. I did the following;

• allowed cookies
• removed passwords
• changed authentication to OAuth2 in both IMAP and SMTP

I got the pop-up gmail/Google window asking me to login. My password is accepted. I am asked to allow access to gmail through Thunderbird. I allow. TB hangs sending security information and then crashes.

I assumed that it must be because I was on an older version of TB. I updated to the latest v91 and checked that the OAuth2 settings are as they should be. All good.

I got the pop-up gmail/Google window asking me to login. My password is accepted. I am asked to allow access to gmail through Thunderbird. I allow. TB waits of a bit and pops up a failure notification. This happens every time. If I click on "Get Messages" or I click on any of my folders, I get the gmail login popup, and I am asked to allow TB, AGAIN, and then failure. I cannot get past this.

I have done enough searching again, but I cannot find anything that helps. Can anyone here help with some guidance please.

I have uploaded shots of the various windows.

Thanks.
