Thunderbird Support Forum

I have two computers, one older with TB 115.9.0 32 bit, pop. The other has 115.9.0 64 bit, imap, same email address. I have tried to merge them, but when i do the Thunderbird Import folder has zero messages and no subfolders. I also tried changing the old TB to IMAP, didnt work: "configuration problem". Any help would be appreciated.

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

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

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?

I accidentally started the upgrade to 115 and aborted it. The "What's New in Thunderbird 115" now pops up every time I run the "old" version (102.15.1). It is my practice to close all running apps at night before I have the computer go to sleep mode. Consequently I have this message starting my default browser every time I restart TB. It has become annoying. There must be something I can do to stop this. I looked in all the appdata directories but couldn't find anything obvious. I also looked in the update directory but nothing obvious to me there either. Can you provide a fix for this?

I have not upgraded to 115 because too many people are having problems of one sort or another. I do not want to search for help to patch problems resulting from the upgrade process. When problems settle down a bit more, maybe then.

Give that I use TB as my desktop client to access my nyu.edu email (provided by google), and that recently I updated my password as periodically requested by nyu admin When I try to access nyu email a pop up screen come up asking to authenticate with imap.gmail.com. I click next and get a 403 Access Forbidden error (Authentication failure while connecting to server imap.gmail.com.)

Solutions I have tried: 1. Clear cookies, history and cache on browsers and TB; 2. Changed default browsers (Ffox, Ch, Edge); 3. Deleted account in TB and created it again using instructions here https://www.nyu.edu/servicelink/KB0016473 4. Accessed my nyu email on browser to check user name and password. It works. I can access the email.

Nothing seems to work. Still get 403 error. As a result I am unable to authenticate and hence use the email account in TB.

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?

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

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.

TB v115.8.0 (64-bit) Closed the app and went to dinner Came back and opened the app. All the tasks are GONE!!!

I know TB keeps everything in text files, so I found the "calendar-data" folder and opened some files using NOTEPAD.EXE to find keywords I know represent my tasks. Sure enough, the data is there in the sqlite files.

What's the secret code that simply decides to not open those files and populate my task window?

Hi, I use thunderbird ver. 115.9.0 on Garuda Linux Gnome (Arch based distro). From some time I noticed I cannot copy in app. I cannot copy text from messeges or copy text from popup window with thunderbird version. I try to change theme but it don'y help.

Regards.

Last week, sometime, I received ALL the emails, that have come into my "mailbox", from about the time I purchased my latest computer, several years ago. There must be hundreds, if not thousands, of the little critters. All arranged alphabetically, starting with the letter "a". So far, the ONLY solution I've found from "Thunderbird Help", is to 1. Open inbox 2. Select [left click] one of the repeated emails. 3. This high lights the email in BLUE. 4. Select BOTH "CONTROL & A" KEYS at the same time. 5. This highlights the WHOLE PRESENT page of emails in BLUE. 6. The instructions then say to press the "DELETE" key. 7. Question is- IF I PRESS THE "DELETE" key, will that just delete the emails on this page, OR delete EVERY email in my entire "inbox"? The only OTHER remedy I've tried, is to send the unwanted emails, ONE at a time, to the "TRASH" folder, then empty the "TRASH" folder, when I get 10-15 emails in it. That could take a VERY long time. Awaiting your suggestion[s]-Joel Payne P.S. Might this happen again? If so, it may be time to go back to Carrier Pigeons.

Hey there Team!

So I flipped my table because of the new Outlook update and I'm beyond frustrated.

Not only it does not show the unread email count but also stopped working for my work email, making me miss a serious meeting!

This is ridiculous!

So now I'm transitioning to Thunderbird however, my Inbox is showing the total amount of emails. This is not what I need. What I need is the unread amount of emails.

On top of this, if I minimize the email, the Inbox amount count merges with the amount count of Sent Items. This is not what I need either... What I need is to solely have the amount of unread emails.

How can I achieve solely unread email count with Thunderbird?

Please keep me posted as I'm losing my last screw over setting up something as basic as this. -Val

Yesterday I downloaded Thunderbird to Windows 10 (64-bit), added my Office 365 (for work or school) account, rocketmail account and iCloud account. I created unified folders for the three accounts. I have downloaded the TBSync add-on with the required CavDev (?) one to connect my iCloud calendar.

After successful use the first few times, now Thunderbird becomes unresponsive within 5 seconds of opening, every time, rendering the program unusable.

Troubleshooting mode does not fix the problem, so I assume it's not the add-ons, nor does starting my PC in Safe Mode (F4 at startup ie no networking), so I assume it's not antivirus.

I uninstalled Thunderbird and re-installed from the website today. All my accounts were there (so I wonder if the uninstall didn't work properly, although I assume that it's just the files left on my computer that the new Thunderbird installation is accessing).

All these attempted fixes leave the problem unchanged: the window freezing within seconds of opening.

Because the program becomes listed as 'not responding' and greys out on further clicks, I have to hard-close the program using Windows, selecting 'Close the progam'. Clicking 'Wait for the program to respond' leaves the screen greyed out, and nothing changes for at least 20 minutes (the maximum I've tried waiting it out). This also means that it does not yield a formal crash report, because Thunderbird does not recognise it has crashed.

On one occasion it did create a crash report, which I submitted. I am not sure what behaviour allowed this to happen, and I have been unable to reproduce it. That particular crash ID was as follows:

Crash ID: bp-41096385-eebe-4ccc-a47e-f76300240417

Any help much appreciated! I'd love to stick with Thunderbird if possible.

Hello all together,

i just reinstalled my whole pc, win10 64. I exported my profile including all possible data, the .zip was too big to import so i copied it into the profile folder, on my desktop, in another foldet etc. But i always get the error message shown in the picture. This is my only chance to have access to my (partly) old email accounts... that's why i followed all steps, but i cannot import everything. I REALLY need your help and would appreciate it A LOT.

Thank you in advance!

I have installed TBSync for my addresses/contacts. Syncing works correctly between Thunderbird and iCloud (both ways). However, new entries created in Thunderbird (although correctly syncing with iCloud on the net) do not appear in the Mac Contacts app on the Mac desktop. Strangely, these entries appear on my iPad Contacts app. It is only entries created in Thunderbird that do not sync through to the desktop Contacts app. Yet I can create a new entry in my desktop app and it syncs through to Thunderbird correctly. I can also edit any entry on Thunderbird created on an Apple device and the changes go through to all my devices. It seems that the format used when creating a new entry in Thunderbird is creating a problem in the syncing process between my iCloud account and the desktop app. Any ideas?

I used the "A" key on a message in my yahoo account and it did not go to any of the Yahoo archive folders. Can't find it in the trash either. Any ideas about where this message might have ended up? Thanks

I've got a Fastmail account, and have set up CardDav according to Fastmail's guide to get set up with Thunderbird.

Once my contacts synced, I was unable to see my contact lists in the Thunderbird contacts sidebar, nor can I add a list (the button is greyed out). Is this a known issue? Is it Fastmail specific, or a CardDav thing?

Running macOS 14.3, Thunderbird 115.9.0

When encountering a problem with a new release and wanting to downgrade back to an older (working) version - especially if some plugin I depend on hasn't been updated yet. The current version is well marked, but it would be helpful if the older versions had a subject line like "Release 115.x.x (github commit id)" so we can do better than walk back one release at a time. All flatpak examples for rollback show meaningful subject lines, but Thunderbird and other flatpaks I actually use don't seem to.

1. flatpak remote-info --log flathub app/org.mozilla.Thunderbird

Hi!

I presumed that the settings for copies to self when sending works for both replies and forwards, but I just discovered that it only works for replies. That is NOT satisfactory, and not logical - if you ask me.

I think it worked until about 2 years ago, when Thunderbird was seriously damaged by "updates", and has not yet recovered fully...

I have attached an anonymized screenshot of the "Place a copy in" settings. The sending email address is behind 3 of the erased areas. Only "Bcc these" is different.

Any solution would be appreciated. Thank you.
