I use Thunderbird 115.18.0 on a Windows 7 machine. I wish to transfer all my Thunderbird data to a machine running Linux Mint 21.3 which has Thunderbird 128.12.0esr. I have not been successful after many tries. Could this be because the Thunderbird revisions are different? If so, can I get 115.18.0 to install on my Mint machine? If not how should I proceed? I have already tried creating a new .thunderbird directory with ********.default directory from the other machine. I have also tried a new .thunderbird directory with a the ********default-release directory as directed by one site.

Is there anyway of completely installing Thunberbird on a different drive and not have any stuff including symlinks in the users home directory?

Installing Thunderbird on a different drive/location is documented and straight forward but it insists on putting stuff in the users home directory C:\Users\<user>\AppData\ .

The problem can be fixed by using copying everything Thunderbird related in the C:\Users\<user>\AppData\ to the other drive and use symlinks from C:\Users\<user>\AppData\ directory to its new location. Thunderbird seems to be ok with symlinks.

In earlier versions, the calendar list button appeared in the left sidebar, so I could decide which calendars to display and change the default color. But I can't find this now. How can I change an existing calendar?

Hi Thunderbird, At the weekend we accidentally completely deleted some Gmail emails from Apple Mail . These were also deleted from Thunderbird (2 Gmail accounts) on our PC. We recovered the emails, in the process having to change my Google Password. Whilst the deleted emails returned, one Thunderbird Gmail account was not receiving new incoming emails. (one account is) The emails are arriving as normal into Gmail. After various unsuccessful attempts to to connect to the server I deleted the defective Gmail account from Thunderbird, using the Red Button in account settings, hoping to then be able to reinstall it as a new account. When I attempt to reinstall the now "deleted" account I get the yellow "Unable to log in at Server" message. . The password I am using to add the account is the same as the one I use to sign into that account on Gmail (set on Monday), but it does not seem to be working on TB. I tried the trick of not putting in the password when setting up the new account but this did not work either. I am using TB 140.6.0esr Any suggestion please John

Several days ago we inadvertently deleted batches of emails from our two Thunderbird Gmail accounts on our PC and Apple devices. The lost emails were duly recovered but only after having to change my Google password. However one of our Thunderbird Gmail account will not download any new messages coming in. Ultimately we deleted that account from Thunderbird, intending to reinstall it. We deleted the account by pressing the Red button in account settings. We confirmed that messages are received to Gmail's Web page Inbox Now when I attempt to reinstall the account and press Add Account, I get the UNABLE TO LOG IN AT SERVER MESSAGE shown below. The "Your Full Name" I am putting in is the name on the Google account deleted from Thunderbird, and the password I have tried is my new Google password. I have tried the process of not adding in the password until requested to do so but this did not work either. Any suggestions please?

Hello everybody. Since today or yesterday, my Thunderbird has stopped refreshing the list of messages. The number of new/unread messages in the Inbox and other folders is shown and updated right but the main window with the list of the messages does not get refreshed and only shows the last message from couple days ago.

I've tried to follow a bunch of guides and ideas (repairing folder, deleting .msf files...) and even removed the account and tried adding it again. The list of folders is right but now there are no messages at all. All folders look empty.

I've found out that in the folder on the disc where there are supposed to be the "INBOX.msf" and "INBOX" files, that the "INBOX" file without the file type is missing. And it's the same with every message folder, there are only .msf files on my PC where I removed and re-added the account. On my laptop, the "INBOX" file still exists but does not get updated.

This thing is happening with only one of my e-mail accounts, the others get updated fine and new messages are shown. It is IMAP server, imap.atlas.cz, Port 993, SSL/TLS with a password.

Can anyone help please?

I'm using Thunderbird 140.6.0esr (aarch64) on a 2024 14" MacBok Pro running MacOS 15.7.3 (24G419).

I manage fourteen email addresses, with most of the traffic going to one primary account, either by direct addressing or forwarders from others of the addresses. Maybe not the most efficient setup, but it means I don't have to scan 14 different inboxes to find the messages I most need.

I currently use ±89 filters on this primary account to file messages in a LOT of mailserver-based folders, and a few folders on the laptop. ±90% of the traffic gets filed in server-based folders so I can use any device to access message history. (I should probably note that these filters and message-threading don't always play nice together.)

For a long time, one of the message filters I'll call "Filter BS" successfully filed specific messages in "Folder BS," a server-based folder 2 levels below the inbox. Folder BS also has 2 levels of sub-folders within it for annual and monthly filing.

Some time ago, I began to have problems with messages of many kinds (subjects/sources/etc.) going missing. Eventually, I searched and found them in Folder BS. In response, I deleted Filter BS, looked for but didn't find other filters responsible for these unexpected results, and managed incoming BS-related messages manually. But despite Filter BS having been deleted, non-BS-related messages still get "lost," meaning incorrectly filed in Folder BS, which is acting like a rogue black hole, sucking up everything that gets too close. I have not been able to identify any criteria for what turns up in Folder BS beyond "lots of stuff that doesn't in any way belong there."

Speculating that something's "off" with the BS folder's directory in a way that would be nearly impossible to fix, I'm trying to figure out the least inconvenient, least risky way to solve the problem.

Not knowing other ways I might compound the problem by making big moves with the MANY messages archived in the BS folder's 7 annual subfolders and their 12 each subfolders; and not knowing how to back up server-based in-box sub-folders, I'm stuck at an impasse.

How should I proceed?

Thanks in advance for any input.

I changed my Windows 10 Thunderbird password 3 weeks ago. Every day since then I have not received a single email on my S23 Samsung cell. When I go to log into my Micros account to enter my password I do not have and cannot add or replace an old password. How about I make a donation to Thunderbird for an answer that works?

While reorganizing and renaming a local mail folder it has become inaccessible from Thunderbird. All the other folders are fine.

The folder name is BSW and the BSW file is present, so are the .msf and the .sbd. 1. I tried repairing the folder, no difference. 2. I've tried shutting down Thunderbird, deleting the .msf and restarting. No change in behavior but the .msf file is recreated. 3. I tried shutting down Thunderbird and renaming the files. No change.

Is there another way to get Thunderbird to access the folder?

I have just installed Thunderbird v146.0, set up the first mail account (POP3) OK, then tried to set up a GMail IMAP account. I inadvertently gave it the wrong password, so the Account hub throws out the connection with an Authentication error "Unable to log in at server. Probably wrong configuration, username or password".

The problem is I can see no way of amending the password; if I try and set up the account again, it just skips the "enter password" step, presumably because TB thinks it already knows the password for this email account. I have tried the following:

- The "edit configuration" feature in the account hub doesn't have a change password option - The Saved Passwords section in Settings > Privacy & Security doesn't show the Gmail creds, presumably because it failed to set up this account in the first place - I reinstalled TB, having previously deleted the Profiles folder in C:\Users\<username>\AppData\Local\Thunderbird; everything I've read on this suggests this is the one and only place where TB keeps its data. However, when re-entering TB, the POP3 account I set up is still there, so there must be somewhere else that TB is storing its data, I guess the Registry?

Am I missing something? I can't be the only person who has had this problem!

Thanks

Dear community members, Since receiving the Thurderbird release 140.4.0esr on Oct 14th, I have not been able to send email from any of my accounts (2xIMAP and 3xoffice365 through OWL). Nothing has changed in the account settings. Receive works ok. The usual easy fixes do not seem to work (restart, firewall switch-off, etc.). Any ideas beyond having to rewind to an earlier version and rebuild the whole thing (hopefully not!)?

Thank you for your help! Heli

I'm using the latest version (145) and I've setup my office 365 email account. I'm trying to setup my calendar account as well but when I enter location, username and password it says that my credentials were not accepted.

I assume this means that TB is using legacy un/pw authentication which is no longer supported instead of OATH2. There is, however, no option to select OATH2 in the calendar setup process (like there is for email).

Are office 365 calendars supported by TB 145?

Hello, My SMTP server uses Let's Encrypt certificate. The website with the same domain has no certificate. Thunderbird refuses to connect to my SMTP server. Test connection to the server (STARTTLS) in account settings sais "The secure connection to the server failed" (or similar. I see bg localization). Another server with Let's Encrypt certificate. Test pases. Clicking View certificate shows webserver cert (from DigiCert Inc).

I can't send emails! :)

Hi All,

Just wondering what the roadmap is for multisearch functionality?

I might be a bit dim, but how do you actually search the support forums, as I suspect that this question has been asked before. There are no results returned for multisearch or RFC 7377 or ESEARCH.

Also is it possible to return search results as a vertical list instead of tiled responses, there's a reason why google doesn't do this.

I was working with thunderbird today. Was in a specific email folder I had named "reference" that I use to store various emails, probably around 50 emails in there. Suddenly they all deleted from the folder as I was watching the screen. Checked spam/trash folders and nothing. Also logged into my webmail provider and nothing there either. Any idea what could have happened here? They just seem to have literally vanished. Have used Thunderbird a number of years and never experienced anything like this.

we are unable to sign into tundsrbird using correct creditials. we worked with geek squad and they senr our mail to webnet. the tech told us we would not lose any email that were in thuderbird. when we ckecked they were all gone. there is very inpotant information in there. We would like to restore thunderbird and retrive our lost emails.
