Thunderbird Community Forum

The theme keeps resetting randomly to "dark" - although it shows that the "light" theme is enabled - it still switches to "dark", i.e. the interface is the dark mode. I then have to Disable and Enable the Light Mode for it to be Light mode again. But, then even within a few minutes, while I might be doing something else - when I go to Thunderbird, it has switched to Dark mode again .... This is FRUSTRATING.

Because my previous Thunderbird profile appears to be corrupted, I am trying to reconstruct it without too much duplication of effort. I have started with a virgin profile and added 3 mail accounts by way of the account wizard.

1. One of the accounts is an iCloud (Apple) account. Thunderbird offered to add my iCloud "Reminders" to Thunderbird's calendar, but the resulting entry shows a yellow triangle with an exclamation point, which seems to mean that it cannot be synced. The corresponding iCloud mail account appears to sync without problems. What must I do to enable the "Reminders"?
2. I also need to import the mail from the "Local Folders" in my old profile. Under "Tools - Import", it looks as though selecting "Mail Messages" will import all mail, which will likely result in hosing my profile again. How can I import *only* the mail folders form my old "Local Folders"?

Windows 11 crashed trying to install Fedora Cinnamon. Had to uninstall and reinstall. Cannot setup Thunderbird without PW that I cannot remember. Just setup new PW for Mozilla, will this work to reinstall my Tbird? Thanks,

Hi,

Drag-and-drop of messages in my Thunderbird install has quit working (for a number of weeks now). I've put Thunderbird into Troubleshooting Mode, but it still doesn't work. Also, went ahead and permanently disabled all add-ons and reset Thunderbird settings back to default (actually removed a few out-of-date add-ons as well). Still not working. Tried uninstall and reinstall. Still not working.

Thanks!

tl;dr: How do I import Outlook Express messages?

Background: I used Outlook Express until Microsoft killed it, and have used Outlook 2013 since. Now Microsoft has forced me to abandon that due to Oauth2 not being supported, so I am looking for a replacement.

Thunderbird seems to be a recommended solution, but despite poking around in the community forums and help files, I am not finding straightforward answers to my questions on the current platform. (Side note: I have been using Firefox since it was Phoenix and then Firebird, and then Firefox, but never really used Thunderbird.)

I have a lot of really old .dbx files from Outlook Express. I heard that it is possible to import these into Thunderbird, but can't find any way to do so. These are low priority as they are archives and I just want to view them now and then, so not a deal breaker, but is that possible? It seems like it might require installing quite an old version of Thunderbird to make this happen? I thought I had found an article about it quite some time ago, but I just read through all of the search results for "Outlook Express" and couldn't find anything about bringing the messages in.

I cannot open my Thurderbird account. I keep getting an error "Non-overidable TLS error recorded. Handshake error or probably the TLS version or certificate used by server mail.atlantic net is incompatible.

I cannot get or send any emails. What do I do?

I’ve read all the archived queries about this issue. I’m running Windows 11, get my mail via POP, do use folders for sorting mail, but have an Inbox with way too many messages. Once this is fixed, I will do a better grooming the Inbox. The problem started three days ago as a result of my weekly backing up of Thunderbird using MozBackup. I found the very helpful reply by Toad-Hill on 11/7/23 to a similar query, and assume something got corrupted during the backup. (I’ve noticed that folder names get garbled sometimes after a backup.) Following Toad-Hill’s instructions, in Profile Folder > Mail > my-server, I’ve renamed “Inbox” as “OldInbox,” and a new Inbox shows as created in the folder for my mail server, along with a new Inbox.msf .

Now when I open TB, OldInbox exists, and I can read the messages in it. It contained multiple copies of one new message, apparently downloaded every time I tried to Get Messages. BUT ... Inbox continues to show the same old list of emails that used to be there, doesn’t allow me to read any of them, and I still get the error message. Somehow TB isn’t using the new Inbox that was created in Profile Folder > Mail > my-server. I’ve tried clearing the startup cache to no effect. FWIW, I see that in Profile Folder > Mail > Local Folders, there’s an Inbox.msf dated over a year ago. The Sent.msf, Drafts.msf, and Trash.msf in Profile Folder > Mail > Local Folders are up to date. What do I do now? Is it safe and appropriate to copy the new Inbox.msf from Profile Folder > Mail > my-server into Profile Folder > Mail > Local Folders in place of the old Inbox.msf there?

tl;dr: How can I import Outlook 2013 messages into Thunderbird?

Background: I used Outlook Express until Microsoft killed it, and have used Outlook 2013 since. Now Microsoft has forced me to abandon that due to Oauth2 not being supported, so I am looking for a replacement.

Thunderbird seems to be a recommended solution, but despite poking around in the community forums and help files, I am not finding straightforward answers to my questions on the current platform. (Side note: I have been using Firefox since it was Phoenix and then Firebird, and then Firefox, but never really used Thunderbird.)

I found and attempted to follow the instructions for import here: https://support.mozilla.org/en-US/kb/thunderbird-import but it must not work with older versions of Outlook, as I got a message saying "No profile found." (I ran it under the same user, an admin, that has the Outlook 2013 installed, so I don't know where it is looking for that profile). Import from a file doesn't give the option to use the Outlook file types.

So, given that, how can I import my email and address book from Outlook 2013?

Thanks in advance!

Even though Thunderbird is not my default email client, when I create an email out of my Access database, Thunderbird intercepts the outgoing email and loads instead of Outlook. If I uninstall Thunderbird, Outlook opens as usual.

I recently donwloaded and set up the thunderbird app on my windows PC, but I enconter a issue which I cannot fix. Indeed it's impossible to connect my @outlook.com account ("User is authenticated but not connected") altought I succeed to connected with my @hotmail.com account I really not understand why I looked for on the web and no solution worked. Any solution to propose me ?

Thank you

Bonjour à tous,

J'ai un problème depuis ce matin avec thunderbird. Je n'ai absolument plus accès à la messagerie et ne peux plus rien faire avec l'application (installée sur Mac). Tout d'abord, voyant ce problème, j'ai redémarré l'ordinateur, pensant que l'application s'était mal ouverte. Ensuite, comme rien n'avait changé, j'ai pensé que le problème venait de la mise à jour de l'ordinateur, alors je l'ai effectuée. L'ordinateur a redémarré, seulement, le problème persiste. J'ai téléchargé en double l'application thunderbird afin de pouvoir utiliser de nouveau mes boites mails en faisant bien attention à ce qu'il n'efface pas l'ancien. Le nouveau fonctionne mais pas l'ancien et j'avais tous mes mails en dossiers locaux que je dois absolument récupérer ! L'application fonctionnait très bien vendredi.

Ci-joint une copie de ce qui est affiché sur l'application et donc sur mon écran. Peu importe sur quoi je clique, rien ne fonctionne, y compris sur le menu du haut. Quelqu'un saurait ce qu'il se passe et comment récupérer toutes mes données s'il vous plait ?

I am experiencing an issue when importing `.ics` files into a Google Calendar integrated with Thunderbird. Specifically, when I attempt to import an `.ics` file containing multiple events into my Google Calendar through Thunderbird, only the first event is imported; the subsequent events are not added. However, when I import the same `.ics` file into a local calendar within Thunderbird, all events are imported correctly.

Steps to Reproduce: 1. Open Thunderbird and navigate to the Calendar section. 2. Ensure that a Google Calendar is integrated and active. 3. Attempt to import an `.ics` file containing multiple events into the Google Calendar. 4. Observe that only the first event is imported, while the others are omitted.

Additional Information: - Thunderbird Version: 128.4.3esr (64 bit) - Operating System: windows 11 64bit - The `.ics` file in question has been validated and functions correctly when imported into other calendar applications and local calendars within Thunderbird.

I have researched this issue and found that other users have encountered similar problems when importing `.ics` files into network calendars, such as Google Calendar, via Thunderbird.

Request for Assistance: Could you please provide guidance on how to resolve this issue? Is there a known workaround or a planned update to address this problem? Any assistance or recommendations would be greatly appreciated.

Here, as a sample, the ics structure that I've tried to import: BEGIN:VCALENDAR VERSION:2.0 PRODID:-//Your Company//NONSGML v1.0//EN BEGIN:VEVENT UID:event-2@_EXPORT_ICS.xlsm SUMMARY:prova 1

Hello I have a problem where I get an error message "Unable to use profile when you launch an older version of Thunde...."

I noticed that I had 2 versions of the program installed, 115.16.0 and 128.3.3. Thunderbird must have been running okay up to v115.16.0 as I had to do manual installs from then to now. Initially there seemingly was no indication of any problem. I'm not sure how many manual installs I did as it was only 15th Oct that this issue started. I was on holidays for 6 weeks Thunderbird was unused between about 28th Aug to 15th October. So, my Thunderbird was running at 115.16.0. I tried to uninstall 115.15.0 but it said I had another version that needed to have the uninstall completed by rebooting the PC. I did that but 115.16.0 still remained. I uninstalled 128.3.3 successfully. 115.16 still wouldn't uninstall, so I used a program to cleanup all of this version. I reinstalled 128.3.3 and still get the same problem I started with. "Unable to use profile when you launch an older version of Thunde...."

How can I get Thunderbird running? Regards Alllan

I recently changed my password to a passphrase. Thunderbird 115.16 ER Linux could not/would not handle it. By changing to a password based on the passphrase, Thunderbird sometimes works fine.

I had to change my Microsoft password and I believe it didn't change for my TB email account. I no longer know the old password (I use Keeper to make pw changes). I get a pop3 account password error and no longer can get email in TB. I am currently unhappily using Outlook. I made changes on my pc to meet the new requirements mandated by Microsoft: incoming server - pop3.live.com:995; SSL/TLS; 0Auth2 and outgoing server - smtp.office365.com:587; STARTTLS; 0Auth2. Appreciate some help. Thanks

after latest update nov 12 128.4.3esr 32 bit my wife can not access our same email server mail.patokalakemarina.com. Gets security alert of invalid certificate. When I try to add an exception says is good and don't need an exception.

My 64 bit machine took the upgrade ok, no alert, and her android phone still accesses. Every box is checked the same as my 64bit. How to roll back an update?
