Thunderbird: форум сообщества

I have saved relevant e mails to local folders in my Thunderbird account on my Applemac. I opened up Thunderbird on my MacBook and downloaded my Thunderbird account but it did not copy those local folders, merely 1 empty folder. Without these also shown in my Thunderbird account when I am away from home, I cannot see those records. I am struggling to find a solution. Are you able to help please? Alan Dowler

I just upgraded my desktop pc from Windows 10 to 11, and before the upgrade I used the Tools Export function to export my complete Thunderbird profile, so I could import it after the upgrade. Unfortunately the export file cannot be read on my upgraded pc using the Import function - Thunderbird gives me error messages every time, that suggest the exported folder might be corrupted or invalid.

My IMAP emails are fine, as I have set those accounts up from scratch and the folders have now populated with all the emails - the problem is all my filed emails, dating back many years, which were all stored manually in a filing system under Local Folders.

I tried manually copying across the individual files from the extracted back-up folder into my live Thunderbird profile and then reopened Thunderbird...which worked to some extent...as in, all the folders are there, but no emails are showing! It shows no messages under each folder, even though if you look under the Profile you can see that the email files exist.

I tried various ways to bring them in, including zipping one of the folders and trying to import from the zip file (which also brought in a folder but no emails) but even though the email files are clearly there under my profile, Thunderbird shows 0 messages in all my Local Folders. It's as though it is unaware the files exist, so I suspect it needs them to be formally imported somehow?

I would hate to lose the emails, as they document important information and purchases etc over many years, along with archived emails for my charity work, social events, etc. As I said, I can see the files are there but simply copying the files to my profile has only worked to the extent the filing 'structure' is visible, Thunderbird doesn't display any of the emails.

I have included two images...one of my Thunderbird Local Folders as they currently look, and the other showing the backed up files existing in my Profile, which I hope are helpful.

Can anyone help please? I am running a desktop PC on Windows 11. Thanks, David.

When I reinstalled Thunderbird, I got my account back, but the Local Folders were missing. I found where they're hiding on my computer, but I can't figure out how/where to copy and paste that folder so they show up in Thunderbird. Can someone walk me through those last steps, please?

Thanks

I inadvertently deleted a mail sub folder named Shopping Oder Confirmations I found the folder in my acronis backup and copied it to my desktop I then pasted it in to the profile window of thunderbird in hopes that when i restarted it would show up in my mail folders which it did not I can send you screen shots of the different windows where I dropped the folder Can you help please?! There is tons of information in these folders I reference often. Thank you! BTW I did just make a donation :)

To be clear, I seriously doubt the problems I am encountering are TB's fault! The problems may be my fault since I've grown older, I've tended (believed) using new versions of software present my mind a BIGGER challenge than using the older software/version I have been successfully using? I'm still using Version115.10.1

After our ISP chose to start using Zimbra Oct. 7, 2025 and their tech support could not assist me in getting TB working the had me remove POP3 settings for TB and change to IMAP with their software.

FINALLY someone helped me get TB working with IMAP. For 3 days grrr. Now the ISP says I need to use their web mail, Zimbra.

So might downloading the current TB version and somehow get the In box, all the folder contnets etc. over - into the new TB help?

I was going to backup everything tonight, now I have little to NO hope, without help!

THANKS & remain WELL plus be SAFE!

On the 20, of October I was forced to re install Windows 10. Kept my data but I had to re install all my apps. With Thunderbird I follow the same procedure I used with Firefox: After installation I copied the profile folder from my backup and replaced the new one. That worked out well. With Thunderbird, I followed the same procedure, all my emails where there but not my local folders. I am attaching several snapshots to illustrate my steps. Image 1 "local folders now" Image 2 "Profile Folder". (why there are 2 sub-folders)? Image 3 "Mail in the profile folder" Image 4 " List of folders in my Local Folders" The are there, how do I get them back on Thunderbird in the correct place "Local Folders"? Thank you for your help again. Regards Ilio Pieroni

I converted my old Outlook emails in to MBOX using the Syscurve conversion software, and then moved the MBOX file into my Local Folder for Thunderbird. When I open Thunderbird it sees the file, but does not see the folders or messages inside the file. The Local Folder has the following three files in it (plus the trash, etc.): output_20251127110416.mbox 4,194,310 kb output_20251127110416.mbox.msf 2 kb output_20251127110416.msf 2 kb Thunderbird shows the output_20251127110416.mbox in the Local Folder but says no messages found when I click on it. How do I get Thunderbird to see the mbox files?

This is second request (can't find the first). I need to import multiple (bookoo) .EML files into TB 115.10 to later move into "folders". Several weeks ago I somehow found someway to import a single .EML file (downloaded from an old ISP) into TB -- and then got busy with other projects -- and now cannot figure how I did it. I did not use an extension (ImportExportTools NG) -- just the native tools in TB 115.10. If anyone is familiar with importing EML files -- sure would appreciate suggestions. Thanks.

Copied Thunderbird Profile from Windows 10 PC, pasted to Windows 11 PC - No email history or address book

I followed the steps to copy the profile from the old PC and paste it into the folder on the old PC.

Thunderbird is using that profile, but there are no email history or address book.

Hi, I've set up TB successfully on a new PC and been using it a while. Then I noticed my local folders archive group of subfolders was missing. I followed some instructions about moving local folders file across from the old to the new version.

Now I see the individual archive folders without the folder group name 'archive'.

Also, there are a couple of other files not visible on the new platform although they were in the original installation local files and were copied across.

I was careful to ensure the same version running on both PCs. Also that TB was closed when copying files across.

Any pointers appreciated!

Hello all:

Transferring Thunderbird from the system above to the system noted above. Follow the instructions from here on the Mozilla Support page (copied both "Thunderbird" directories into the Roaming and Local destination directories. When the destination machine installation opens, it is functional (i.e. it picks up all the existing e-mail accounts, downloads new mail, etc...). The problem starts when we get to the local folders.

All of these have a date and time appended to them in the destination installation. For example, if the original folder is "Prosperity Bank" the destination folder is labeled "Prosperity Bank (2025_09_21 23_06_33 UTC)" and will not let not populate (shows no messages inside).

As I am typing this, it seems I may have identified the problem (or at least part of it). It seems the destination system install is slowly working its way through the local folders randomly (not in alphabetically order), as it seems to be slowly populating them with the old mail stored therein on the original system. It is going very slowly. Very slowly.

Has anyone else experienced this? Is it normal? Is there any way to quickly eliminate the dates now appended to the local file names? (Visually this is very annoying and I do not want to try modifying the individual folder names yet until I'm sure its populated as much as it will populate.)

Thank you for any assistance.

Hello people, I've just upgraded my Thinderbird because my inbox didn't load on opening the programme. I guess I have made a huge mistake somewhere in the process, because my whole archive has disappeared. I very much hope it still exists somewhere and that I will be able to restore it with your help. Thanking you in advance, Nele Ysebaert, Amsterdam

I have Thunderbird on the old computer. For twenty+ years I have read the instructions for moving it to the new computer. i cannot understand/am not at all confident in my ability AND I have only ONE keyboard/mouse. I have to move it from one computer to the other to operate them.

Right now all email is on the old computer, no email is on the new computer. No email has ever been on my cellular telephone. One set of periforals - keyboard/mouse.

I DO have the Bravura, the Plugable transfer cable and accompanying software, and many other things came across, but not the Thunderbird.

I want to do the move/installation correctly so that not one stored email is lost or corrupted.

I need help.

My Thunderbird (windows) is really not working, so I want to reinstall the whole thing. I have 4 accounts and a local folder. I don't want to backup all the profiles before reinstalling, as I am having an annoying issue with g-mail (I don't HAVE a gmail any more, but Thunderbird wants to login to gmail every time I open it). I only want to backup the "local" folder, as, so I want to reinstall the accounts one by one from scratch. In that way I hope, I can purge Thunderbird of the gmail. Now the question: How do I backup the local folder in a way that makes it easy to import it back after all the reinstallment?

Tuesday Oct. 7, our ISP converted to a new e-mail program. I could NOT log in/on I called our ISP's help desk. The 'technician' could not help me log in to our Thunderbird POP 3 account. He had me, WITHOUT asking if I had essential - legal - medical-etc. e-mails in the IN BOX or in folders! He NEVER warned/cautioned all ?would? be lost - GONE.

I URGENTLY need to recover all TB POP3 IN BOX & e-mails in folders. I need to access legal messages today, if possible.

If Mozilla does not have a recovery program, what do I do? I am not seeking to recover ' deleted messages (unless his having me change from the POP3 account to a 'new' IMAP account is the same as ' "delete" '.

Any & all prompt responses APPRECIATED! Remain WELL & Be SAFE!

I changed POP3 email password to an app password and Thunderbird would not recognize it even though I updated in Security. I was told to delete the Thunderbird account then set it back up which I did--I did not check the box to delete files. Finally the new account was able to bring in new emails (POP3) but the old folders/emails are not there.

I read that I should go to %appdata%, roaming, Thunderbird but the dates are from years ago--do I go further to find my data or is there another path or something else I should do?

Unless they were backed up somewhere within Thunderbird, I don't think I have any backup.

Can you please help? Thank you.

I would like to download hundreds of emails from Thunderbird to my PC for archiving purposes. How can I download one of my folders from local folders? I tried using AI but it didnt help me at all.

Mon compte thunderbird a été supprimé En réinstallant Thunderbird, j'ai récupéré la réception des mails récents et le carnet d'adresses mais perdu les messages envoyés, en instance , les brouilons, les archives. Je les vois toujours dans C/Utilisateurs/nom/Appadata/roaming/Thunderbird/Mail/pop.sfr.fr et ensuite dans archives.sbd et inbox.sbd . Comment les importer dans thunderbird. J'ai essayé l'importation du profil sans succès. Merci de votre aide
