Thunderbird Support Forum

Thank you in advance for your time.

I have been using an older version of Thunderbird for many years, in part because its seems certain upgrades caused problems with my emails. Nevertheless, I am very happy with Thunderbird, hence the reason why I still use it.

I backuped all of the required files (Profiles) and then did an unistall and re-install as I was having problems with 1 specific email (its an office 365 email and seems like always problems with them).

In any event, after reinstalling and making sure I have the right local directory, I am still not seeing my email accounts or folders.

Again, local directory name is correct as:

C:\Users\Name\AppData\Roaming\Thunderbird\Profiles\frjfw3yx.default\Mail\Local Folders (note I changed my first name to just Name for the purpose of this post).

Anything I am not doing correct or forgetting?

Help would be greatly appreciated.

Many thanks.

I had a functioning thunderbird, but due to my host provider I had to change some of the configuration (new has (owl) suffix). This left 2 profiles. The new profile wouldn't work until I deleted the original. I did a save so I have all the files, now which ones need to be restored and where. I want everything under the new profile.

which are the actual files to be moved, msl, sqlite (-wal.file, -shm.file, msf file, .

Trying to transfer email accounts from old to new computer, but cannot access any messages on two accounts, both gmail, but a third has transferred correctly. One of those accounts contain additional folders accessible via the inbox. Followed instructions as shown on your transfer information page. Both Thunderbird instances are the same version. I can send and receive to the empty accounts and all others within Thunderbird. The account data is contained within the transferred Profiles/Mail folder but does not show within the program. All other data, including calendar events, have transferred successfully. Where have I gone wrong, or how can I remedy the situation?

Hello, I just installed Thunderbird 102 over a previous installation on Windows 10. I had 6 account/mailboxes. At the restart of Thunderbird, I had only 5. The account "katamail.com" is gone and I cannot see my messages. But they still are inside "E:\POSTA\Mail\pop.katamail-1.com\" . Or, at least, I hope so. There, there are the file Inbox and Sent of several megabytes. How could I recover that account? The other 5 have been read/recovered automatically... Many thanks for the support! Matteo

In the course of having my computer rebuilt, the techs had to wipe the C: drive and install a fresh, up-to-date copy of Windows 11. Needless to say, I have had to rebuild my software, one program at a time. After setting up Thunderbird, I was able to import the mail from a second machine on my network. However, that left me missing a large chunk of mail from earlier in 2023 and later 2022. In looking through all the profiles, I find that the messages whose date matches my missing mail are in appdata/roaming/thunderbird/profiles/default.sja. That directory contains two subdirectories, cache2 and mail. Under cache2 I have directories called doomed, which is empty, and entries, which has all of the messages whose dates match those that I am missing. My question is really simple -- how do I get those messages into my current user profile? I've tried the import tool, but that fails. I am at my wits end on this one. Any help would be appreciated. Thanks!!

I had to reinstall Thunderbird due to a computer issue. Thunderbird was uninstalled then down loaded and installed. I have confirmed with Spectrum, email server provider all the correct setting for the incoming and outgoing configurations. For the incoming the are IMAP, mail.brighthouse.com, port 993, connection SSL/TLS with authentication by Auto Detect. Outgoing is mail.brighthouse.com, port 587, connection Auto Detect, authentication by Auto Detect. Thunderbird program will not connect servers, message indicates email address, password or server information is incorrect. This information with Spectrum has been confirmed twice, multiple attempts have been made utilizing Spectrum's protocol and Thunderbird will not connect to servers. The latest attempt stated "Login to server mail.brighthouse.com with username failed" and is prompting me to provide the password, which is provided correctly and confirmed by logging in directly to Spectrum email with required password. Failure continues and I have been working on this for close to 4 hours. How do I solve this issue?

Thunderbird. Trying to export filters by copying and saving msgFilterRules.dat then pasting into settings for Thunderbird on another computer. The file is greyed out and inaccessible. Advice on how to be able to copy this file from one computer and then paste it into second computer Thunderbird.

Many Thanks

Hello,

Recently changed from GoDaddy Microsoft 365 to Gmail. Changed the POP settings on both incoming and outgoing servers to match the Gmail settings. Whenever I check email, it pops up a Microsoft 365 login window. I cannot find any references to the old MS365 settings in the Thunderbird account setup.

Any ideas? are there hidden settings someplace I need to change?

I had a backup failure and had to patch together my Thunderbird installation along with stacks of emails. All good except that I have a copy of msgFilterRules.dat related to my Inbox but it is not detected and consequently no filters. Being lazy, I don't want to retype 15 years of accumulated filters. I suspect that the name on the primary Inbox is different than before and that is causing the failure to associate the filters with the current Inbox. How is this association made? What could be stopping it now? Is there some way to force the filter file I have to be associated with the new Inbox?

Am trying to import my .pst files from outlook 2019 into thunderbird. Have tried using import tool. Get to step 2 and does not asllow me to specify location of the .pst file. what am I doing wrong?

A problem has arisen with Thunderbird. There are solutions for problems like this, but none quite like mine or current. I have Windows 10 64 bit OS, x64-based processor and Thunderbird 32 bit 102.10.1. I do not know why 32 bit Thunderbird is installed; 64 bit seems more apt.

I have run check disk, bad sectors marked on the C: SSD, which has a 99 per cent health reading on Crystal Info. Data is on an external drive, also good with no percentage cited.

There are two active email addresses on Thunderbird, both IMAP. The one that is not Gmail works fine. Gmail does not work well. Occasionally headers are downloaded, which does not matter much. The main problem is that Gmail emails vanish from Thunderbird, causing them to be downloaded again, much data volume. This has happened several times.

There's a folder C:\Users\Owner\AppData\Roaming\Thunderbird\Profiles\tb.default\ImapMail\imap.gmail-1.com\Painting.sbd that seems to hold the painting emails. There's another folder C:\Users\Owner\AppData\Roaming\Thunderbird\Profiles\tb.default\ImapMail\imap.gmail.com with painting.msf painting painting.sbd There are similar and identical folder names in TB for Gmail and non-Gmail, so the above three may refer to the non-Gmail folders. The ~\imap.gmail.com folder (the second one above) does not have many folders with the TB folder names.

One solution may be to delete all the ~imap.gmail-1.com\*.* folders and download the emails again. I'm unsure about this and advice is sought. Thanks.

I am reading emails from my ISP on G-Mail on my desktop, laptop, and phone while using Thunderbird on my desktop to hold all my messages as a backup. I want to leave G-Mail and use Thunderbird as my sole e-mail app. I have not done so because I can only access Thunderbird on the desktop. With the arrival of an Android app for Thunderbird, I would like access to my profile files from the cloud so that I can get my messages on all three of my devices. Can this be done, and if so, how?

I'm using Thunderbird for the first time. The problem I have is following: I have about 6 GB mails stored in gmail. When I have start using thunderbird, I was able to upload automatically about 3 GB mails on the local folder of my computer. After that the automatic upload has stopped. When I click "Get message" button only 2 or 3 new mails are uploaded. Obviously this isn't solution for transfer of another 3GB mails from gmail. Wondering how to proceed further and what is the problem? I have about 150 GB free space on my pc. Thank you in advance for your advice and help
