When I upgraded from MacOS Ventura to MacOS Sonoma, Thunderbird stopped working. Getting it to work the first time required me to use Apple's 2 Step Verification process to create an app-specific password. After the MacOS upgrade, that process was no longer available. Apple switched to 2 Factor Authentication, which is apparently different and incompatible with 2sv. The other websites and applications on my iMac have already switched to 2fa, and I'm not sure I can have both methods active on the same computer (but I've asked, Apple, anyway).

Is there a recent change in Thunderbird that would allow me to use 2fa instead of 2sv to access Thunderbird?

I have many years worth of emails in Thunderbird that I can no longer access. I can see the directory structure, and some of the email lists, but not the content.

Thanks for the help!

created new accounts but sub-folders different, missing, new, & new icons(?)

For many years I have had 2 Accounts in Tbird. They are POP. I just created two new accounts, and am confused by some differences in appearance. These are IMAP. Do IMAP accounts populate the sub-folders based on a structure present in the IMAP provider?

1) there is a new sub folder "All Mail"

2) No Junk folder. There is a Spam folder. Did some idiot change the name in an update to Tbird, just to fark with long time users? If so they did a poor job, since the Account Settings still has a tab for "JUNK Settings" and the toggle asks where to move the JUNK. Creating synonyms is bad practice, because nobody knows if they are in fact synonyms. One would presume they are not.

3) In the index listing of accounts, each account has an icon to its left -- concentric circles with a padlock. And I have not noticed that icon before, I'm wondering if my old accounts suddenly have a different icon (which strangely matches the new accounts' icons). The sub-folders all have unique icons for each type (Inbox, Sent, etc)

In choosing where to place sent mail, there are two toggle choices to Place A Copy In: 1) "Sent" folder on { [circle&lock icon] ACCOUNT_NAME 2) "Other { [SentFolderIcon] Sent on ACCOUNT_NAME I don't grasp the difference. Would 1) keep the messages on the remote IMAP system? I notice that my old POP accounts are using option 1) & mail is kept locally.

3) The new accounts have "greyed out" italicized subfolders "Folders" and "Labels." Are these associated with being IMAP, or did some Tbird update add them? What are they for?

I can still receive and send e-mail from my phone and tablet (using BlueMail or GMail), but I can't do either from my Windows laptop with the new Thunderbird 60. If I reinstall the earlier version, (Thunderbird-Setup-17-0-8.exe), everything works. Going to Yahoo to change my password, as one solution suggests clearly does NOT address the problem, as the only thing that does not work is Thunderbird.

Outlook says that it will no longer let third party mail apps like Thunderbird to access Outlook email as of September 16, 2024? What do you recommend?

"Action Needed – You may lose access to some of your third-party mail and calendar apps

Update your sign-in technology before September 16th, 2024 to maintain email access.

The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

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.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

I am trying to get my contacts from Windows 10 Mail , to Thunderbird , first off , i cant find the contacts in Windows 10 mail ( i can't find the actual CSV file/folder/location , second , if this is a common issue why doesn't Thunderbird make it easier to transfer contacts , just like all the other email programs do ??? , i am confused as to why its such a pain , i am also not impressed with the speed Thunderbird has in actually sending emails , Widows 10 Mail is 10 times faster at actually sending the mail.... , the only reason i was going to switch to Thunderbird was so i can send more than 1 picture at a time in a email , which Windows 10 Mail has a problem doing and its taking forever for support to help , but if i can't easily get my contacts transferred , i am back to square 1 ,

I need a step by step in getting my contacts saved/found in Win 10 Mail , and get them into Thunderbird ... any help that actually explains the entire process is needed , as some of the links i have seen in other posts just say to save the file , but it does not tell you where the file is and where to save it (some said something about Office ???) , it makes no sense why this has to be so complicated , all i should have to do is go to "Import Contacts , choose the email program they are in , select it , and import it , that is how every other email program does it , if this can't be done without spending hours trying to hunt down the info , maybe it was a bad idea thinking this is a good email program , so far , i am not impressed , if it gets better then fine , but if it continues like this , its getting un-installed and was a waste of my time

I have installed thunderbird, but the sub folders in my webmail are not downloading into the thunderbird application. Thunderbird automatically did imap when I added my accounts. I have no idea what the problem could be. Thank you for your help.

Can current Thunderbird (52.5.2) still import old mail from Outlook Express (on Windows XP SP3)?

Or should I try to install an older version like v38.5.0?

I also have my mail in Outlook 2003 & 2007, but I read Thunderbird hasn't been able to import from a .PST for a long time (since v.17 or so). Let me know if I'm on the right track (and which track is best). I stuck with Outlook far too long. Any help would be greatly appreciated.

Help! TB 60 continuously crashes on all of our machines so we're using 52.9 until the bug is figured out, BUT TB insists on auto-updating to version 60 despite turning off auto-update settings. These are the exact non-default update settings we have. Can you help me figure out why TB continues to auto-update?

user_pref("app.update.auto", false); user_pref("app.update.channel", ""); user_pref("app.update.enabled", false); user_pref("app.update.lastUpdateTime.addon-background-update-timer", 1536598499); user_pref("app.update.lastUpdateTime.background-update-timer", 1536598626); user_pref("app.update.lastUpdateTime.blocklist-background-update-timer", 1536598371); user_pref("app.update.lastUpdateTime.search-engine-update-timer", 1536599735); user_pref("app.update.lastUpdateTime.telemetry_modules_ping", 0); user_pref("app.update.lastUpdateTime.xpi-signature-verification", 1536599607); user_pref("app.update.migrated.updateDir", true); user_pref("app.update.service.enabled", false); user_pref("app.update.showInstalledUI", false);

Fx 124.0

Why am I getting these notifications? I have the latest version, but this prompt not only asks me to update, but there's no mention that it will install the beta 125.0 beta 1

I've - I hope! - followed all the Thunderbird Support instructions on moving a Profile from one computer to another with a different OS (save a copy of the profile file from the first computer, download and install TB on new computer, locate its "Profile" folder, and then either paste the contents of the former profile file into the new profile file [thus overwriting the latter]), then open TB . . . but it didn't work.

I then tried the same, but with a slightly different method: I copied the name of the new profile file, gave it to the old computer's profile file, then renamed the new profile file, and pasted the old profile file -- now with the proper new name -- into the new directory. . . that, too, didn't work.

I've spent a few hours trying to get this to work, and am nearing the point of giving up on TB as an email solution.

Any help would be very welcome!

My previous question on this was not resolved.......can anyone help please?

I have an old vista 32 bit PC with windows mail. I have bought a Windows 10 32bit PC I have followed the instructions from this link https://support.mozilla.org/en-US/kb/switching-thunderbird#w_switching-from-windows-mail-or-windows-live-mail-to-thunderbird for exporting the emails on the Vista PC into a folder on a My Book Essential drive. Looking at the properties of that folder it has 3GB and 18,333 files. I then plugged the My Book Essential drive into the Windows 10 PC and followed the instructions (from the same weblink) to import the folder into Thunderbird. The export took about 10 or 15 minutes on usb2. The import seemed to be far too quick and only took about 15 seconds, albeit on usb3. It appears to have imported the folder structure but none of the folders seem to contain any emails. Please can you suggest what I should do?

The files on the USB have an EML extension When I double click on them from the windows 10 pc with Thunderbird installed, they open with Thunderbird.......although not in the same screen as the one in Thunderbird that opens up with my accounts set up.

Thanks David

I am having trouble manually configuring an AOL email account (username@verizon.net). AOL's instructions say to manually configure the account. I tried to do that twice, once with IMAP and the other with POP.

Now, I have two email folders in Thunderbird that I cannot use. They are both empty because I get a message box that says "Login to server imap.aol.com with username@verizon.net failed." when I try to use them. When I use the same login credentials to login to the website mail.aol.com, they work.

I have to contact AOL as to why when I try to access the account with an email client (Thunderbird and Outlook) I'm getting password errors. In the meantime, how do I delete the two email folders created incorrectly in Thunderbird?

Thanks for your help.

Hey folks, I recently started the process of migrating my accounts from POP to IMAP. I have several accounts set up on Thunderbird which have been getting mail via POP for years. The idea is to migrate all these accounts to IMAP and I've started the process on one of the smaller accounts, but have already ran into issues with server time outs due to the quantity of mails I'm trying to copy over.

I set up both the POP and IMAP account for the same address on Thunderbird and manually set up the folders (or labels on GMAIL) on the IMAP account to replicate the set up of the pop account. Setting the folder structure manually is not a problem, the problem I've run into however, is that when copying any large amount of mails from the POP account to the IMAP account, it just doesn't seem reliable.

The progress displays in the status bar, but on transferring a folder with about 2,000 emails, it seemed to time out and not transfer everything over. I then had to go through a long process of comparing emails in each folder to know what was left to transfer.

I'm yet to transfer much larger accounts, some with tens of thousands of emails and I need to be sure everything gets transferred properly.

Can anyone suggest a tool or add on or method that even if the server times out, that it can just continue where it left off and I can be sure that all the mails will transfer eventually? I understand the upload process can be slow and I don't mind having to wait or doing it overnight, just as long as it's done right and I'm not left having to compare thousands of accounts, folders and mails.

Any help would be greatly appreciated!

I run Mac OS X version 10.11.6, El Capitan. I have used Apple's Mail.app for many years. I'm trying to convert to Thunderbird, version 52.5.2. I have successfully created a TB account, but I have not been able to create usable copies of any of my Mail.app mailboxes in TB.

I have faithfully followed "Importing Apple Mail messages" in the page titled "Switching from Apple Mail to Thunderbird". That method thinks it works, but imports exactly 0 mailboxes.

I also went through all of "Install, Migrate and Update" multiple times, but nothing there helps.

Finally, I tried TB's Events and Tasks --> Import... path, but that processes only files of types .ics (for calendars) .csv "Outlook Comma Separated Values (*.csv)" (or .ics for calendars).

I did discover that Mail.app has an "Export Mailbox..." option, which will produce a mname.mbox directory for each exported mailbox. I've tried getting TB to use that as input by copying it to the Local Folders directory before starting TB. TB somewhat recognizes the .mbox folders that are there, but it doesn't show the mail to me when I select them.

So the question is: How DO I get my current mail copied to TB?

hi i'm at my whits end trying to get my data across from windows mail. I paid someone to sort this, and he said it will continue to say the connection is lost while getting data across from windows mail. its been a week now. i cant get it to work properly. none of my addresses are there, mail continues to not arrive at my PC (when I've got it on my phone), it just keeps saying loading message 1 of 3457. but never gets to the total. the number has remained the same for many days now so obviously its loaded all the emails, but it still appears stuck. also the preview window seems to not work (has worked once or twice). frustrated...

dont want to buy stupid microsoft products but i just cant work this way?

I am using Kubuntu 13.10 64 bit OS and Thunderbird Ver 24.4.0.

I transferred my old profile in to the new system and eventually found where it goes but as advised previously I went to "Help | Trouble Shooting" and clicked on the "Open Directory" button alongside "Profile Directory" tag... the button does nothing. That's the bug, "the button does nothing"

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

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?
