Thunderbird Community Forum

My Thunderbird installation (159.0/Windows11) has evidently just updated, and my Calendar tab is suddenly a complete blank space. There's a support article here that appears to discuss exactly this situation, and gives precise steps for getting into "Config Editor" in Advanced Settings, entering a long search string, and issuing a Reset command. (Mail and contacts are just fine.)

Which I tried...

But there is no "Config Editor" button in the dialog I get when clicking Advanced Settings at the bottom of the Settings tab, only a mostly blank screen with no list of settings and a dialog box in which one can enter text (with options for "Boolean", "Number" and "String"). And entering the search string given in the support article produces, with a bit of finagling, a toggle that will change its setting from True to False and back again (and a trash-bin icon that offers to delete it), but neither "True" nor "False" produces any instance of a "Lightning" extension in my list of extensions (which is short and uncomplicated), so (a) I can't delete the extension as instructed, because it's not there, and (b) restarting Thunderbird only continues to give me the unhelpfully blank Calendar tab. (And I do mean "blank" here - there isn't even an empty calendar grid on that tab at this point.)

I *think* the article is probably right that my data is still there (I can see .ics files with current dates in File Explorer), but at this point I can't get at it and can't seem to get the interface unstuck.

When I attempt to send an email in Thunderbird I get an extensive string of gibberish that I have to delete before I can send the email. What can I do to get rid of this huge irritation? Thanks

My local Thunderbird program (159.0 (64-bit) on Windows 11) is set to auto-install updates. Upon the update completing earlier today, the inbox and other folders were completely empty. They remain so following a program & computer restart, and also opening the program in troubleshooting mode. I have checked the following: - logging into the online mailbox directly works, and shows all emails - sending a new incoming email to the email address does have the email show up in the remote mailbox but not the local mailbox - sending a new outgoing email from Thunderbird does appear in the local Sent folder, as well as on the receiving email account - the local Thunderbird instance is still able to connect to the IMAP Mail Server (mail.talktalk.net) - the following settings are configured, and I believe haven't changed since prior to the update:

 - Check for new messages at startup is **enabled**
 - Check for new messages every 10 minutes is **enabled**
 - Clean up (Expunge) Inbox on Exit is **disabled**
 - Synchronization & Storage: Keep messages in all folders for this account on this computer is **enabled**
 - Synchronize all messages locally regardless of age is **enabled**

I have ~100gb of space available on my hard drive

I'm not sure what other settings might be helpful. Please let me know if there's anything else I should add.

My issue has two parts. The first is that I want new emails to appear in my local email client upon arriving, as they did previously. The second is that I want to have the full set of emails on my remote account available locally, which is currently no longer the case. There is also no sync activity happening, and apart from establishing the initial connection to the mail server I can't see any activity in the bottom left corner.

I am using Thunderbird as an email client. I have the option set to normally send emails as plain text. If I receive an email that is formatted and then reply, the email is composed as unformatted. I wan the reply to be formatted.

Is there anyway Thunderbird can detect formatting and automatically format the reply the same as received?

How can I reply to an already formatted email so that the reply is formatted?

I had to buy a new computer and reinstall my Thunderbird. I'm running version 158.0.1 (64-bit). When I have an email with a bunch of replies, it always opens each reply in a separate tab. In the past, the solution was tools -- preferences -- general but when I got to tools, there's no preferences option and I have clicked on everything possible there and in settings. I need the email to open as a single tab, closing a bunch of tabs is a real pain. I'd appreciate if anyone has a solution they can share.

My e-mail stopped working a week ago. I get as far as "connecting to IMAP but then get a "Login to server imap.orange.fr with username [redacted]@orange.fr failed" message. I have changed the IMAP and SMTP passwords several times but none seems to work. What am I doing wrong?

Hallo,

ich bitte um Hilfe, seit dem letzten Update von Thunderbird auf 159.0 (64-Bit) sind meine Mailaccounts verschwunden. Eins konnte ich wieder einrichten, das von T-Online bringt als Fehler ständig "Fehler bei der Authentifizierung" obwohl alles korrekt ist. Thunderbird kann sich automatisch die Serverdaten für IMAP holen, aber sobald ich das Passwort eingebe kommt der Fehler. Das Passwort habe ich jetzt bereits geändert, dennoch funktioniert es nicht. Was kann ich tun?

I followed the instructions in the aritcle on the search page and it still didn't work. I worked with Geek Squad. They completely did all kinds of different settings and they all failed. When I click the test button, it says it connects successfully.

It tells me to retry or update the password.

I am absolutley typing in the correct password.

I installed the newest update this morning - and since then, the background color in all areas have turned black? I tried to change to white in settings (html selections) - but it does not change. Still black. WHat can be wrong?

For the first time I am trying to add several different email accounts to Thunderbird on my Windows 11 laptop. One worked fine (i.e. second email account). The next, from a different email provider, only has an inbox, no other folders. Local folders now appears below the this last email account, and includes copies of the primary email account Sent folder and my Invoices folder. There are more items in this copy Invoices folder than in the version listed straight under the primary email Inbox.

My aim is to have several different email accounts, each with their own Inbox, Sent, Drafts, Deleted, and the capability to add Folders as I wish. But I am thoroughly confused, having tried and failed to add the usual and any extra folders to this email account. Would be grateful for any advice.

I am trying to migrate from Microsoft Outlook 2021 to Mozilla Thunderbird. I have successfully imported the email from a number of different email accounts. I would now like to import the archived emails held in a number of PST files. The import tool would seem to be what is required, but it does not seem to allow me to select the PST files that I wish to import. I am concerned that it will try to import all email messages from my Outlook 2021. Is there a way of restricting it to just individual PST files?

When I launch Thunderbird via icon ( version 158), it always brings me to sign on page for Thundermail.. If Thundermail is by invitation only, how do I get back to the real TB page. I can access webmail, my account, and portal. I only see Version 156 in download folder and only have default-release and default in the profile. I have no clue then what is happening. Will bringing back an earlier version. "ABOUT" shows version 158 and nothing else.

Also, my android email & passwords have remained constant and I did not have to change anything.

I was a COX cable Email customer, when they stopped providing Email my account went to YAHOO, but the Email address stayed the same. I have been using TBird for years. My old computer died, the person that set up the new one could not set up Tbird. I am trying but it says my cox.net site could not be found. PLEASE HELP ME! I love Tbird and hate YAHOO!

So long as I investigated, the problem is,

After version154, received emails in Japanese encoded by 8bit causes misconversion (mojibake). Emails encoded by base64 is not misconverted. Only 8bit encoded shows the problem. Version153.5 is no problem. Version154 and newer shows the problem.

Here are OK/NG by sender/receiver combination. Sender version154 8bit - receiver version154 - NG Sender version154 base64 - receiver version154 - OK Sender version154 8bit - receiver version153 - OK Sender version154 base64 - receiver version153 - OK Sender version153 8bit - receiver version154 - OK Sender version153 base64 - receiver version154 - OK

Emails encoded by base64 is OK, but some senders can encode by only 8bit. I cannot find how they can use base64. It would be helpful to know to use base64 encoding in version154 (or later).

However, the best way is that version154 (or later) can read 8bit encoded email in Japanese. I would like to thank anyone who help the problem.

Over the past couple of days, I've discovered new mail in my inbox but the new mail icon (with the red dot) doesn't show in the system tray.

I get notifications of new mail, which is fine if I'm sitting at the computer. But the icon in my system tray doesn't change, so I never know if mail has arrived while I was away.

I've tried everything - both in Thunderbird settings and Windows system tray settings - and nothing is making a difference.

Is this happening to anyone else? Might it be a bug?

I have this problem since a couple of days, it is new . When I move my emails in local ordners then they stay in the web.de Inbox on the server and in the app. What can I do that they are automatically deleted when I move them in local ordners?

meine abgespeicherten passwörter werden bei jedem neuen windows-update gelöscht. in firefox wie auch in thunderbird. ich muss dann beim senden sowie beim empfangen in thunderbird die passwörter für alle email-accounts neu eingeben und abspeichern. dann funktioniert es einwandfrei bis zum nächsten windows-update. das geht bereits seit c. 3 monaten so. davor wurden die passwörter bei den updates nie gelöscht. was ist passiert?
