Thunderbird Community Forum

I'm having trouble taking the contents of TBird and IMAP-ing it to a Gmail account (~60,000 messages). I have added the Gmail account as per the instructions on these forums including Advanced Config for IMAP and OAuth2, but no messages appear in GMail. Am I missing something obvious? Do both accounts have to be the same UserID? I don't want to mistakenly transfer the contents of an empty GMail account to the TBird account wiping out 20 years of messages. (I do have exports of all messages, btw) I'd be very grateful for any breadcrumbs that point me in the right direction. Thank you in advance. aj

Using Windows 11 and recently activated Windows Security and removed McAfee antivirus. Since this was completed, MS Outlook would not send emails so I was instructed by my ISP to switch to Thunderbird. Now using Thunderbird and I am able to receive emails but cannot send. Attached are the mail settings that were given to me by my local cable company (MCTV Ohio). Any ideas how to fix this so that I can send emails? The message just "clocks" showing sending for hours...never actually sends the email. I know the issue is not on the end of the ISP because I am able to send on their web, just not through Thunderbird.

I don't seem to be able to get threading to work for me in card view. I have downloaded the add on and i am still having challenges. Can you help me understand what i am missing?

Adding a Google Calendar causes Thunderbird to be non responsive!

I have added several other calendars, and these all work fine, just this one Calendar causes the problem.

The calendar seems fine when viewed in Google itself. It is a busy calendar with events going back several years and forward at least 2 years.

I am using the Provider for Google Calendars. I am on the latest stable version of Thunderbird.128.5.2esr on Windows 11.

Closing Thunderbird and restarting does not remove the issue; TB stays unresponsive.

Is this a known issue? How can I diagnose the issue with the calendar.

Thanks in advance.

David, thank you. I think with your help, I have it fixed. I only had one prefs.js. (I had to go look for the file.) Anyway, just the one file. It was dated in 7/x/2023. No files named prefs-1.js or ........ prefs-46.js. So I checked the properties of the prefs-js file. It was marked read only. I unmarked read only and closed Thunderbird and reopened it. Twice now. The account I wanted to delete did not reappear and the account I wanted to add came back!! I am very pleased the solution was so simple but I would never have found it without your help and clues.

How to permanently set line spacing to "Single Line Spacing" in emails, any online solutions do not work in Thunderbird version 128.5 64 bit.

I used to able to do this easily and effectively but with the new version of Thunderbird I don't seem to be able to get it to work.

Any working solution would be most appreciated. Thanks.

Hello,

I have several email addresses with Thunderbird. When I open Niels.Wichmann@gmx.de a password is requested which I no longer know. Under privacy and security => saved passwords there is no imap for the account, smtp exists. I can access the account with my app on my cell phone. How can I set a new password or how do I get the password? I can display all other passwords.

Regards N. Wichmann

bold textI share an info@ ..... e-mail with colleagues. We used to be able to mark = colour e-mails so e.g. I could colour blue to my colleague an he could colour green for me.

My two colleagues can still use this function but I can only use it on my own laptop.

What can I do to make the marking seeable for my colleagues as well as myself? We have tried updating and restarting which does not solve our problem.

Not sure there is anyone answering questions in this forum now. Maybe Thunderbird doesn't exist now? I have used it for years but can't get a response from anyone on what my problem is. Keep getting message the the connection to sever timed out. Before that the message was the certificate wasn't valid for the server. Can anyone help??

I am just a non-computer-literate old woman. I have tried to follow advice from the community forum. All that SMTP stuff is Greek to me. Since the last update to Thunderbird, I can't reach my daughter or my neighbour. One uses Hotmail and the other Yahoo. sometimes after about 4 days my neighbour will tell me he finally got a message.

Please change this. The only way I can reach them is to leave Thunderbird for webmail. It's a nuisance. Can someone please advise.

I am about to set up a new Windows 11 laptop. The old one is a Win10 one, running Thunderbird 128.4.3 32-bit. Note I haven't upgraded to 5.2esr yet. My Thunderbird profile as recorded by Mozbackup is about 16GB - most of this is archived in Local Folders. I have 15 email accounts (using four different domains, none of them are gmail or hotmail etc) and a newsgroup.

I've looked at various answers (and problems!) around these factors and cannot see the wood for the trees. Can anybody tell me - or direct me to - a clear description of how to go about this? Some questions are:

1. Can I install 64-bit on the new laptop and copy over the old 32-bit profile? If not, is there any problem in continuing to use a 32 bit Thunderbird? I am getting a lot of hanging/not responding in the current TB. Note I haven't upgraded to 5.2esr yet.

2. How do I ensure that all the archived mail is transferred without problems? I haven't compacted anything lately, since I noticed that sometimes a message stub is retained where the message body seems to have disappeared, and that compacting risks deleting even the message stub, which can be useful.

3. I've been using MozBackup for ages now but it is really ancient - is there a more up-to-date backup that would be reliable?

Thanks in advance! I'm planning on do the new installations at the weekend but anything I can do to prepare would be useful to know!

I am trying to turn off the message that I get saying "Mozilla Thunderbird Email wants to access your Google Account". I cannot figure out how to turn this off.

Just make it stop. I reply to deny but it keeps coming up.

Just make it stop.

I use Microsoft Outlook for Windows from time to time and discovered it is possible to sign/encrypt emails with an S/MIME certificate even if the email on the certificate does not match the "From" email address. Although this is disabled by default, it can be enabled by following these steps: https://learn.microsoft.com/en-us/previous-versions/troubleshoot/outlook/how-to-turn-off-email-matching-for-certificates

I wonder if there is an equivalent mechanism for S/MIME and/or OpenPGP certificates imported into Thunderbird, whether by changing settings in the config editor or otherwise?

Just wondering if this is a bug or user error/misunderstanding. See attached images. I have entered the address for a contact and listed the gmail account as the default. But when I start typing the name you can see that the sbcglobal account comes up first.

What' up?

My Thunderbird installation has started hanging (unresponsive) more than 50% of the time that I waken my computer from sleep on Windows 10. It's been going on for over a month; I am currently running 128.5.2 esr. Never had this problem in the past - I've been a Thunderbird user for years across multiple devices (Windows, MacOS, iPhone, iPad).

What steps or information should I be taking to either resolve this issue, or collecting to help understand what's going on?

Suddenly I cannot open Hotmail in Thunderbird. What to do? Note that I have Owl installed in Thunderbird Here is what I am seeing when I open Thunderbird

I'm migrating Thunderbird from my old Windows 10 computer to a new Windows 11 computer.

I've installed Thunderbird v115.12.2 and successfully moved all my accounts, emails, calendars, etc., to the new computer.

Several things are NOT working correctly, though:

1 - Settings will not open. Here is the message from the error console:

Error: No such tab mode: preferencesTab

   openTab chrome://messenger/content/tabmail.js:758
   openTab chrome://communicator/content/utilityOverlay.js:257
   openPreferencesTab chrome://communicator/content/utilityOverlay.js:295
   openOptionsDialog chrome://messenger/content/mailCore.js:628
   oncommand chrome://messenger/content/messenger.xhtml:1

   openPreferencesTab chrome://communicator/content/utilityOverlay.js:295
   openOptionsDialog chrome://messenger/content/mailCore.js:628
   oncommand chrome://messenger/content/messenger.xhtml:1

2 - Customize menu does not open

3 - The hamburger menu in the upper right corner does not open

4 - The spaces toolbar on the far left is missing

5 - Events and Tasks are missing from the menu

6 - My calendar is nowhere to be found - I can't find a way to access it (on my old computer, I clicked on the calendar icon in the spaces toolbar on the left side of the window)

Thunderbird on my old computer was also running v115.12.2 when I backed up the profile folder to move it.

I tried downgrading to Thunderbird v102. I had all of the same issues listed above PLUS all my accounts and emails disappeared. -- I've brought it back up to v115.12.2.

Could someone please help me get Thunderbird working correctly?

Hello,

I try to create a TB account for a mail account *@outlook.fr. The account is not the current MS account of the windows session.

Every thing is well set (joined screen capture). Following [https://support.mozilla.org/fr/kb/microsoft-oauth-authentification-thu...] I should get , as described (french translation of the article): Selon la documentation Microsoft, les administrateurs et administratrices doivent visiter « https://login.microsoftonline.com/{tenant-id}/adminconsent?client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753 » et accorder les autorisations suivantes afin d’autoriser Mozilla Thunderbird : IMAP.AccessAsUser.All, POP.AccessAsUser.All, SMTP.Send et offline_access.

But I get the "connect to an MS account" (see joined screen capture).

If you validate (giving the password) then you have changed the current account of the Windows session which cannot anymore operate in normal conditions (particularly changes the current user of MS365 applications).

Imagine that you have to activate several *@outlook.fr sessions, what could be the issue. In another way, as it is an IMAP account which is a "multi-user" function, several users are normally able to connect simultaneously which is opposed to MS account which cannot (must not - built for) be connected with several Windows sessions simultaneously.

Consequently something goes wrong when you setup an outlook.fr mail account. It looks like the two connection : - connect MS365 account (linked to and id by *@outlook.fr) for contextual use of MS365 applications - connect to *@outlook.fr mail IMAP account to manage mails are somewhere confused.

for now, I am unable to setup the configuration of mail for a team where several are using Thunderbird as mailer and others Outlook, while everybody of the team must have access to the e-mail of the team which is an outlook.fr mail account.

Best regards, Trebly (trebly_auth)
