Thunderbird Support Forum

Title. Thunderbird is a really cool client but it's pretty slow. I blame that on the thousands upon thousands of emails that my hotmail and gmail each hold. I don't necessarily want to delete these emails, but I have seldom a reason to have any email older than 2 months in my thunderbird client slowing and crashing the program whenever I want to combine inboxes.

To this end I went to "Synchronization & Storage" and told it to "Synchronize the most recent 2 months" but it didn't delete the huge cluster of older emails. The next option is to tell TB to delete these emails in the same menu but as I understand it that would also delete them in the server, which I don't want to do for posteriority.

What do I do?

I have an email account with IONOS and my wife has an account. We have had these accounts for several years. Recently my wife can not send email. We are configured the same and I do not have a problem. Server: smtp.ionos.com Port: 587 (tried others at IONOS support request) Security STARTTLS Authentication: Normal password. When she tries to send or forward with a simple text (one letter or larger, it does not seem to matter). She gets the following reply: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Transaction failed Reject due to policy restrictions. For explanation visit https://www.ionos.com/help/index.php?id=2425&ip=198.177.53.191&c=hd&r=0MQ4Bx-1rqmFh0x4l-00ErW3. Please check the message and try again." When trying to go to that web page, it does not exist. I have gone to IONOS support and we have both looked at the configuration and can see no differences between my set-up and hers. I have deleted all email address from her machine and reloaded Thunderbird (115.9.0), restarted her machine and added back her email. Same results, she can receive but not send. If she uses her phone, it works, and if you go to the IONOS web site and use there service it works. I'm at my wits end and can not figure it out. I have also opened an incident with the IONOS Postmaster, which I think is their second level support. Please help.

I updated Thunderbird to the latest version and now I have a problem that continues to remain after closing the process.

Thunderbird 115.10.0 64bit (Build ID 20240412173147) OS Windows_NT 10.0 22631

I have latest Thunderbird version (115.9.0 64bit) on fully patched Ubuntu 22.04.4 LTS.

I'm trying to get it to display Day-of-Week for old messages - is this possible? I have tried all sorts of combination as detailed HERE to no avail.

I'd like concise instructions on how to do this (if it can be done). I do not believe trying a new profile will work as I need to test this for old messages - at least for messages older than a week.

From the link above, I can the Day-of-Week to work for the current week - but that only displays the day and time. What I'm after is as shown in the attached Outlook screenshot. Also see the closest I can get that to match in the Thunderbird screenshot.

Thunderbird ściąga mi cały czas pocztę i dubluje. Zapycha mi komputer. WIem, ze mam skrzynkę 50Gb a na dyzku mam prawie 200 Gb w pliku, wg mnie ściąga raz na jakiś czas pocztę. Co mam zrobić? Arek

I'm about the 100th person to have this problem, so I have spent the better part of two days looking at all the threads and possible fixes. Like all the others, with no warning, my TBird stopped being able to send messages through Spectrum. It did NOT start immediately after I updated TBird to 115.9.0 (in March) but just three days ago. I have three roadrunner addresses in TBird, and one other one associated with a website I have. All have the same problem. My phone and my iPad send messages just fine.

I tried all the fixes that worked for some. They didn't work for me; I continued to get various, inconsistent Send Message Errors. I have come back to the recommended Spectrum setup for the outgoing SMTP server: mail.twc.com, Security is STARTTLS, Port 587, Authentication is Normal Password, my username is my email address. Of course the problem is not fixed.

What DID work was putting TBird in Troubleshooting mode, using the Spectrum setup above. While that is adequate, I would much rather find out what is wrong. I have Matt's 10/7/23 11:56 AM answer to someone, asking for the Troubleshooting Information. I will be glad to supply that but I need an answer to this message in order to do that. Thanks! Demaris

I can't use Thunderbird any more. I open an email and I get 7 copies up across the top of the screen. Delete does not get rid of them, and I am up to over 50 at this point. Please contact me directly at [removed phone# from public support forum] when you have fixed this. For reasons I have just outlined, email is not a good way to communicate.

I assume that everyone else is experiencing this disaster.

I have had message filters set up for a long time. Recently I tried to make some changes (adding one filter, deleting others, changing the response). I find that if I close Thunderbird and reopen it, all my changes are gone! How can I get the filter changes to stick?

OS is Win 10 64bit TB is 78.4.0 (32 bit) (is that a conflict?)

For NO known reason TB had to be restarted. Opened, BUT only one folder, NOT the Inbox, is displayed. Cannot see NOR access the Inbox, nor any folder (none displayed). Restarting TB produces the same result every time.

If searched any - all TB headers / options. HELP & support yield no clue(s) nor solution(s).

I have been struggling with this problem for about 6 months now and no-one I've asked has been able to help me. Even my computer guru failed me! I think it was after an update about last June when I started having this problem An nothing I've tried has had any effect. I had a Geek Squad guy on the phone with me for about 45 minutes to no effect. He said he'd never seen the problem before. I have business emails on that account so I don't want to risk losing them. Can anyone help me please? Christine

Hello My Thunderbird failed pop access to my Gmail account, at beginning of month. Any try to fix, and even change from pop to imap don't work. I get the windows as shown i images as result. I don't like see oauth/legacy/consent in the URL. - Change setting in Google from pop to imap - Cookie setting updated as forum suggest - JavaScript true as forum suggest

Any hint on forwarding step? Thanks Lars Granath

I am an e-mail packrat.... I have a pop e-mail but keep years and years worth of old e-mails (inbound and outbound) some with big attachments. My backup for the few e-mail accounts I have within my profile is approx 13 gigs. I've moved machines... and currently running Ventura on my imac.

I have to force-quit all the time to get my e-mail working again. It hangs-up.... sometimes will recover... but then... I type a few words or maybe sentences... and back to HANGING-UP again. Sometimes after a Force-Quit... it will behave for awhile. Other times... it takes 4-5-6 force quits in a row to get the program working again. Been having these issues for months... and have taken out all the add-ons etc.... HELP... pulling my hair out! Thanks

Hi, Excuse my poor English (I am French). Linux Mint 21.3 Cinnamon (64), Thunderbird 115.9.0 (64) no added module - Installation from the Mint list of software. My problem : regardless of the provider (Proton, Gmail, Outlook, GMX - in IMAP), the message menu bar (see <https://support.mozilla.org/fr/kb/personnaliser-la-liste-des -messages#thunderbird:linux:tb115>) does not appear. How to make it reappear ? I think I have tried all the configuration menus and possible right clicks within Thunderbird ; I haven't found anything on the Net ; starting in safe mode did not change anything. I come from Windows 10 where I didn't have this problem. Thanks in advance for your help

I use Thunderbird as a central repository for 5 different email addresses. Recently 1 of them stopped getting Sent messages that were created on Webmail or my Phone. I used to work fine, now it doesn't. This account is the only one I have that is set to POP3; the others are IMAP.

I'd change the settings to be IMAP but don'e see how to do that. And, I don't want to lose any messages and would like to capture the ones that have not been captured.

Any thoughts?

Thunderbird runs slow...ie when I type an email I can easily type faster than thunderbird will accept characters....(this does not happen in other applications)...this happened about a month ago, and then stopped ( I have no idea why)...but the problem is back. I am running Ver 115.10.0 build 2024012173147. Rebooting windows 11 makes no difference.... I just tried to enter Troubleshoot mode and thunderbird stopped responding....Top line says Mozilla Thunderbird (Not Responding). Thunderbird is connected to my gmail account. ...and I run IMAP....with 'store all messages on the computer', but thunderbird wants to load every email from the server'

Any advice would be appreciated Rick

I've been using Thunderbird for years and have never had this problem. Since the upgrade today, after I run Thunderbird once and close it I can no longer start it up again. I have to reboot or use Task Manager to kill it in order to run it. This is on Windows 11. Please help - not an acceptable workaround for long. Optionally, how do I downgrade to previous version? I should know better than allow automatic upgrades.

Adding a couple images below, when it has started successfully it shows as one of the Apps in Task Manager. When I close it, Thunderbird drops into the Background Processes but doesn't end. I have to kill it here in order to start it again.

Hi

I have used local Thunderbird folders for my Gmail accounts for a long time, and have now started using Protonmail (via Proton Bridge to Thunderbird) as well. Sending and receiving Protonmail via TB works fine.

I want to keep my single local inbox, sent folders etc. I set up a filter on the TB Protonmail account to copy all incoming emails to the local inbox. Works fine. I have also configured TB's Protonmail account to copy any emails created in TB's Protonmail account to the local 'sent' folder. All good.

I now want to get any emails sent via the Protonmail app to be copied to my local 'TB sent' folder - but have failed to get this to work.

If I create a TB filter to run on the Protonmail IMAP 'sent' folder, it CHANGES the separate TB inbox filter from running on the IMAP inbox, to run on the IMAP 'sent' folder!!!

I want to have two separate filters for Protonmail IMAP - one for 'inbox' and one for 'sent' - but they keep resetting so that both run either on the IMAP inbox or 'sent'. I thought filters were separate entities, but clearly not.

Am I missing something, or have I stumbled across a bug?

Thanks in anticipation.

When I click on an email, I get a bunch of copies across the top of my screen. They are impossible to get rid of, even if I close Thunderbird and re-open it. Please fix it quickly, as it is almost impossible to use!!!!!

when I try to send an email you ask for a pass word for jojack@dslextreme which I havent had for years
