Thunderbird Support Forum

Heya:)

I am a webdesigner and I'm currently designing a website for a client that uses Thunderbird for his mails.

Previously, Domain, website, and email had been hosted with the former agency.

Now we are gonna split this up into 3 different providers:

Webhosting: Squarespace Domain hosting: Cyon.ch E-Mail hosting: Would be great to keep using Thunderbird :)

How can I ensure that my client can still use Thunderbird? Do I just need to change some DNS-records? Otherwise I will have to switch to gmail :(

I have a Windows 10 pc, which is current with all Microsoft and manufacturer (Lenovo) updates. Thunderbird won't run since the last update. It just gives a message saying, "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you want to reboot now?" After several reboots, I have given up. A support forum solution from 4 years ago recommends deleting a file (global-messages-db.sqlite) at a location (C:\Users\user\AppData\Roaming\Thunderbird\Profiles\8charstring.default) that seems not to exist (hidden?) on my pc. What do you suggest? Thanks.

In Thunderbird [Ctrl]+[B] doesn't initiate Bold text, in fact those keystrokes don't do anything at all. Any ideas as to why and how I can make this shortcut work? The other shortcuts for Italics and Underline work fine. Thank you for your time.

Tell me how I can continue to use thunderbird with the above account and also Denis.Clarke.hotmail.com after September 18. I have 4 individual historic E mail accounts and thunderbird joins them together. What do you need to do? To deal with threat below.

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Hello:

So how does one do that?

Attempting a search online results in all about how to copy the PROFILE; haven't found how to get all of my emails over to my external drive where I can access them.

Thank you, Nels

I have read that in earlier versions (TB 102) arrows would appear on the left of the message header indicating that a message had been replied to or forwarded. I'm using TB 115 and there are no such arrows. I tried safe mode, but that made no difference. It would be helpful to see which messages have been replied to or forwarded, and which not.

I recently patched to Thunderbird 115.12.2, and discovered that threading has been turned on everywhere. Reading through the forum, I disabled threading by default in the config editor via mailnews.default_view_flags, and manually went through every folder setting "View" -> "Threads" -> "Ignore threads".

However, it appears that disabling threading is only honored for the inbox. Setting "ignore threading" on any other folder is ignored, and Thunderbird continues to thread.

For example here is the "Sent Mail" folder with "ignore threads" set (see screenshot) and it still displays with threading. Apparently, "ignore threading" only works with the inbox. I would like threading disabled on all folders, not just the inbox. If there was a switch to disable threading universally, that would be easiest for everyone who dislikes threading.

Thanks in advance. John N. jnyhuis@gmail.com

I use Thunderbird for all my emails. With gmail accounts, Thunderbird has an 'all mail' folder but that folder doesn't exist for my yahoo mail accounts.

Is there any way to create an 'all mail' folder (or functionality) with Thunderbird/Yahoo ?

Thanks for any help ! John

Hello My friend is visually impared and is having great difficulty seeing to read emails. Is there any way to use Thunderbird to get the emails and then read them with text to speech to audio. Or can anyone think of another way. I will have to be simple too. Thanks.

Several upgrades ago, I created message filters in Thunderbird to forward emails received from specific senders to other email accounts that needed to get copies. While running version 115.12.1 32bit on Win 10, I had need to delete one of the filters. When I went to Menu Bar > Tools > Message Filters the Message Filters window does NOT show ANY filters regardless of which account (I have 20 and checked each) is selected. I have also searched my HDD, located all copies of msgFilterRules.dat and opened ones that might be related to the account in question. ALL of the msgFilterRules.dat files that I checked had only 2 lines.... version="9" and logging="no", except for the problem account where I had turned on logging and the .dat file showed "yes". I also went to yahoo and checked to see if I might have created the filter on the server side. However, according to yahoo, they discontinued the forwarding filter in 2021, so it's not happening there. I need to know how to find the forwarding filters and edit them.

When I click on a link from thunderbird mail to a specific website, it takes me to a log in page in the specified website where the email is automatically filled in. In firefox browser, I have cleared history for all time, including "form and search history", cookies, cache, browsing and download history, active log ins, site settings, and offline website data. I have deleted my log in for the specific website (the id and password for the site in settings, password section. In Thunderbird, I also deleted, in the Privacy and Security section, all "saved passwords" When I open up the page of the specific website in question, through Thunderbird, I continue to see on the log in page, that an old email I no longer use is entered automatically. When I type in firefox browser the same specified website, the old email address does not show up. That makes me think that the log in information is stored somewhere in Thunderbird, not firefox. What is the solution to remove this information whereever it has been stored?

Hi Cannot send emails via Thunderbird. Sending an email via grahamg.d@ntlworld.com failed (as do my others addresses - not tested this time) with message "Mail server responded - Authentication Code Require (VM401). can you help please? Have been having email problems with Virgin Media for some time now and it has got worse I can receive emails

As of Sunday, Thunderbird can no longer reach my ATT server to download email. It has behaved for ten to fifteen years. Last time someone at ATT fixed it. I have been on the phone or on screen with ATT most of my waking hours since Sunday. (In the process I lost my internet, my landline, my cell connection, etc.) Everything is restored except the connection between Thunderbird and ATT. Everyone thinks changing my password will do it. Done it four times. It gets me into the ATT mail. I have replaced the password in Thunderbird settings with it to no avail. Is there anything you can think of? Not only is Thunderbird more attractive than ATT, I have thirty years of mail boxes there, a continuation from Eudora. I will appreciate your wisdom.

My calendar is Baïkal 0.8.0 running an a debian 10 server. My thunderbird is 115.12.0 (64-Bit) running on Ubuntu 22.04.4 LTS My other devices are two thunderbirds 115.12.0 (64-Bit) running on Ubuntu 22.04.4 LTS and aCalandar 2.8! running an Android 14

It does not matter on which client I add or change calendar entries then synchronize them (I can see on my Baikal dahboard, that the synchronization has succeeded!) the other thunderbird clients don't show the changes, even after explicite synchronization, only after unsubscribing and then new subscribing.

Please advice for help!

Thanks in advance

Please Someone help ?

I have followed all the suggestions I can find, but my Thunderbird Calendar will not sync with the Outlook Calendar on Windows 11. I am using TB Sync, but every time I try to add my Outlook Calendar ? It refuses to accept my Password, even though it is correct, and the User name and email are too ! It shows as error code 401, and cannot authenticate ?

I have tried a suggestion to create an 'App Password' to use in my Microsoft account, but the options described do not exist in my account !

Can anyone please help ?

Updated from Windows 7 computer to a new HP running Windows 11, downloaded Mozilla thunderbird from my old computer I had used it successfully for years, & received all my In-box email but nothing was received in my Sent box. The Thunderbird application works as I sent myself an email and received same, but the entirety of my sent email history never arrived. What to do?

There's an article that says we can change where attachments are stored by going to tools, options, attachments. However, I have no "options" under "tools." Thanks in advance.

Microsoft sent email last night announcing the end of "Normal Password" for Hotmail, and warning that Hotmail would REQUIRE "modern authrentication" beginning 9/16. I have personal desktop subscription to Microsoft 365. I have set Microsoft account to 2FA and checked in Tbird that cookies are enabled.

I have spent hours and days trying & failing. With server imap-mail.outlook.com using OAUTH2, Thunderbird won't sync and shows message saying that server doesn't support the authentication protocol please enter another one. With 2FA still turned on and using Normal Password setting and entering an App Password from Microsoft, the Imap connection is fine about 85% of the time, needing re-entry of the App password about once a day or so (usually requires several tries until App Password gets accepted.)

The 0AUTH2 fails with Norton Smart Firewall turned Off or Turned On-makes no difference.

(Sending email with Outlook and 0AUTH2 DOES work okay.)

I've also tried Imap connection with a different server: Outlook.office365.com, using 0AUTH2.

In this case, Tbird shows me a Timeout error and never makes an Imap connection to the server.  

I've been limping along with the app password, and "normal password" authentication, but now Microsoft announces they will stop accepting connections that are not 0Auth2 ("modern authentication") from Tbird or any other software after 9/16. The clock is ticking. I've tried every remedy I've seen online from Tbird or from Microsoft. Nothing has yet allowed a QAUTH connection for Tbird to a hotmail IMAP server. Please help! !
