I am having issues with Thunderbird accessing emails from Comcast.net. This issue started over the past weekend. Nothing has changed with our Comcast setup or our Thunderbird setup. Please advise.

Thanks. Sam Orner

For my work email, my microsoft exchange uses a different server address besides the default microsoft exchange. When I put that in in the server address, it does not work. When leaving the default, the account also will not get any messages. Are there different settings that I need to change that I am unaware of? Thank you.

In Thunderbird 128.8.1esr (32-bit) Danish language version, on Windows 10, when a list of past notifications pops up, I cannot close them. Whether I use "Turn off" individual notifications one by one, or "Turn all off", nothing happens, except the first time I try, I can see at the bottom left of the screen that communication takes place with the server. But the notification doesn't disappear. On following attempts, nothing happens at all, until I restart Thunderbird, then again I get a long list of notifications from the past that have never been turned off.

As for individual notifications popping up at the scheduled time, I can mostly, but not always, turn them off.

The calendars are no google servers. The problem started occurring 2-3 months ago.

What to do?

I am trying to add a gmail account to thunderbird. I have the following three configurations. They all have thunderbird 136.0.1.

desktop windows 10 laptop windows 11 update 2025-03 23H2 desktop windows 11 update 2025-03 24H2

The desktop windows 11 version fails, and the other two work without any problem. I enter the account name/password, and thunderbird identifies the gmail server info. I enter 'done' and a gmail window opens. It says to allow thunderbird to connect to gmail, enter 'done'. After that, there is a google window that says 'Error 400', and it dies.

Note that the windows 11 version that works is older than the one that fails.

Any help would be appreciated.

Dear community, some days ago my Thunderbird calendar stopped working. It's all greyed out and I cannot add or delete events or tasks. Any help is much appreciated. Best, Wolfram

After Update 128.8.1esr installed on 3/19.2025, I cannot receive or send messages. Worked fine in the morning on 3/19 and after update I get nothing. I have an AOL account for my email. I can get my email by going through the AOL internet site, but nothing through Thunderbird. The previous update was 128.8.0esr installed on 3/7/2025, and that worked fine.

Please put Thunderbird back the way it was. I have several different email accounts in Thunderbird, I'm obviously logged into Google on one of those accounts, but for a while now TB constantly asks me to "Login to Google" - when I already am. i.e. It's asking me again and again, to login to one of the OTHER email/google accounts - and I don't want to, because I bet the moment I do, TB will popup the window again, wanting me to login to previous one. And so round and round we go.

Also the popup is poorly designed, because not all of it fits on the screen. i.e. It's oversized, so you can't see the top or bottom "bar" and there's no way I can see to adjust it. I detest this pointless popup, constantly appearing, having to first click on the white space, and then hit the ESC key to get rid of it (until next time). Why would you do this? We've always been able to have multiple email/gmail accounts, all with different login details, and all the email accounts still seem to be receiving email okay... so why add this annoying popup? Please remove it.

Hello! I am developing an application for an organization that uses Thunderbird in a Windows environment. Among other features, it is necessary to implement the transfer of mail client settings from one workstation to another. Built-in Mozilla Thunderbird tools are not suitable. I am still considering implementation options (autoconfig or direct work with files), and I have several questions. I will be very grateful for any help. 1. What is the minimum required files in the appdata folder that I need to create (transfer) so that the profile works without errors on the new workstation? No need to transfer messages, they are all on the server, and offline work is not used 2. How does the installs.ini file work? I need to avoid creating a new profile when starting Thunderbird for the first time, do I need to create an entry in installs.ini, and if so, where can I get the correct installation code? 3. Is it possible to transfer saved passwords to a new workstation? What are the requirements for this? I am very grateful for any answers

How can I search messages' Date field for a time? e.g. to find all messages at a certain time in any day.

"Date is 18:51" fails to match.

If I create a custom field "Date" which apparently presents the field as plain text, "Date contains 18:51" matches e.g. Date: Sun, 5 Nov 2017 18:51:34 +0000 but I believe fails to recognise time offset.

Thanks.

I got a new PC with Windows 11. I installed Thunderbird, activated the private calendar, and entered events there. For events with a reminder that have a specific duration (e.g., Wednesday from 10 AM to 11 AM), I receive notifications. However, when I create a full-day event and want to be reminded, for example, 1 day before, I don't receive any notification. Additionally, events with a reminder are not shown in bold in the calendar overview (whether they have a specific duration or are all-day events). Can you please help me?

Thunderbird email client 128.7.1esr (64-bit) running on Fedora 41 does not open email attachments except of pdf. The attachments are shown, context menu appears, but click on Open does nothing (except of PDF files, those are opened and shown). All other types of attachment I have to save somewhere and open from there. How to repair it? Thanks, Jiri Rohlicek

Trying to set up a Thunderbird account on a surface book 3 and it refused to accept the password. I did a manual configuration and all the settings are copied from my desktop app so the server settings should all be correct. Now it does all the right things when I click the get messages button i.e. it says 'connected to mail.xxxx.net.au' but that's it. Nothing is sent or received.

I have messages which the message list shows as Date 2024-07-01, 18:00.

But Search Messages with "Date is 2024-07-01, 18:00" fails to find any messages.

Is this a known bug? Any workaround?

I migrated one (just one) of my personal email accounts (from Outlook) to Thunderbird - around 6 months ago. I have other email accounts such as Gmail and Yahoo that I DO NOT use with Thunderbird.

Ever since I migrated that ONE account, I have been inundated with junk/spam emails sent to that same migrated account. No change in junk/spam volume received on my other non-Thunderbird accounts, just this one. I'm asking as it's seems strange, and is the ONLY account that suffers this major annoyance.

Any thoughts as to why?

Thanks,

Hello, this error message appears regularly. The accounts are managed in maildir format.

"The file mailbox:///C:/Data/Email2024/Mail/Post/Inbox?number=28959 could not be found. Please check the address and try again.

Please check the address for spelling, capitalization, or other errors.

Please check if the address has been renamed, deleted, or moved."

What is the problem?

Hi @ all,

When using TB as a LDAP-User, logins.json and key4.db are NOT created on the (mounted) home directory.

here's my setup: Debian 12 with a local user as well as remote users, administrated via LDAP. PAM-login for local and ldap users has been setup and is working. Automounting of network drives is working. Each LDAP user has their home directory stored on a Fileserver and mounted upon login. All applications are working as intended except thunderbird.

So far I've tried to run gnupg locally instead of having it start a session from the (mounted) home directory, assuming that gnupg is the corresponding means of de/encryption. I've copied the profile of the local user to be used as the profile of the LDAP user, logins.json is completely ignored by TB.

Upon starting of TB, passwords are asked for and are remembered in the session. But passwords/logins are not stored and available for the next session.

Any ideas?

Every time I read an email, a tab shows up at the top of my screen. Soon there is a long string of tabs. What is the purpose of these? I have no use for them and they confuse me. How can I delete them all easily and quickly, such as using a keyboard shortcut?
