The import function does not work. I exported a Thunderbird profile in its entirety into a zip file that is only 127 megabytes when extracted. When I go to import the Thunderbird profile, I select the ZIP file, import, and it restarts, and nothing happens.

I have tried the method of going to the profile folder, manually copying the files from the extracted profile, and pasting them into the profile folder and overwriting all of the existing files, which will work for a few seconds- it briefly shows all the emails, and then they disappear. The top of the inbox indicates the correct number of emails, but no emails show up in the inbox, and when I restart Thunderbird, everything disappears.

Hi Folks,

I hope you can help me with my little problem.

Thunderbird was damaged during the migration to the new Mac, so I installed a new version of Thunderbird on the new Mac and now want to get the emails from my old Mac into the new Thunderbird. I think I know where the files for the new Thunderbird are: /Users//Library/Thunderbird/Profiles/xxxxxxx.default-release/imapMail/map.xxx.net, so is it as easy as replacing those files with the files in the equivalent folder on the old Mac?

Alternatively, I just discovered this function within Thunderbird itself: "Import Settings and Data from a Thunderbird Profile." Might this be useful, and if so, how would I go about it?

Thanks for any help you can give me.

Cheers! Chris

Ho effettuato un backup con la procedura guidata ma il file è più grande di 2Gb. Ha creato il file zip ma quando provo a dezipparlo per importare le cartelle dice che potrebbe essere corrotto. C'è un modo per recuperare il profilo? Grazie

Hi, Need help with maps that cannot be removed. Thunderbird downloaded my map configuration, after a new Thunderbird installation, from my online account/my internet provider which was OK. After that I removed all maps on my online account but the maps in Thunderbird is still there but out grayed and I cannot delete them?

I uninstalled Thunderbird and also removed Thunderbird associated maps under %AppData% and %LocalAppData% but when I do a new clean installation same maps shows up in Thunderbird again? I waited some days and did a new installation again, but same issue. I have also deleted everything in W11 cash memory.

Attached picture shows the out grayed "NyMapp and subfolders" I cannot delete. How do I get rid of those folders?

Any help is appreciated.

Bonjour est il possible q un développeur ai pensé à un manière de sauvegarder les comptes paramétrés dans Thunderbird ? et ne me parler pas du dossier profil puisque d une version a l'autre cela ne fonctionne plus!

(je viens d en faire les frais !)

Hello, is it possible that a developer has thought of a way to save accounts set up in Thunderbird? And don't even get me started on the profile folder, because from one version to the next it doesn't work (I've just had to pay the price!).

merci de votre aide thank you for your help

Hello,

We ARE on version 145.

I spend an ENTIRE DAY following this information, especially that section regarding to "alternative method for manual transfer between Windows 10 and Windows 11 computers"

[https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-com...]

IT DOES NOT WORK! I may not be doing something (I could not find it), but in this consideration, I'm wondering WHY it's left there? Does it work for 144. Can I FIND 144?

Thanks, Lizzie's mum

An alternative method for manual transfer between Windows 10 and Windows 11 computers

This section assumes you have a default Windows installation and will work on computers upgraded to Windows 10 from previous Windows versions.

   Locate the master profile folder on the source computer as above.
   Locate the master profile folder on the destination computer as above.
   Note out of interest that your username (indicated by ~ below) on the two computers might be different due to legacy issues, but it will make no difference with a manual transfer as below.
   Close Thunderbird in both computers.
   On the source computer, copy the Thunderbird folders in both Windows(C:)/Users/~/AppData/Roaming and Windows(C:)/Users/~/AppData/Local to your transfer media, in separate folders so you do not overwrite them.
   On the destination computer, remove (or rename if you need a data backup or to preserve an old profile) any Thunderbird folders in the destination folders Windows(C:)/Users/~/AppData/Roaming and Windows(C:)/Users/~/AppData/Local directories.
   Copy from your transfer media the correct Thunderbird folders into the two folders above to replace the ones you have removed or renamed.
   Restart Thunderbird on the destination computer and test it, noting that your inbox tab should be identical to source, but that other tabs may have opened with Thunderbird messages.

I am updating from an old iMac to a new MacMini.

My new macMini does not seem to like my old Thunderbird program so I have downloaded a current version. 

How do I transfer all my old email contacts and old emails to the new platform? I am, in no way, technically savvy so I need simple answers, Many Thanks, John

I'm reading this> https://support.mozilla.org/en-US/kb/thunderbird-export#thunderbird:linux:tb148 Looks great but all of my messages sit on IMAP servers and I don´t need a backup of those. I _do_ need a backup of settings, passwords, pgp keys, to move to another workstation. It is unclear what exactly is exported.

Hi, I'm having issues moving a 10 year old Thunderbird installation on a Windows 10 Pro computer to a new Windows 11 Pro PC.

I looked at all the guides & prior support messages and followed the instructions carefully. My old Windows 10 installation was in a custom directory (G:/Program Data/Thunderbird). I ensured it was updated to the most current version and closed it before moving files. I installed Thunderbird on the Windows 11 machine, went to Troubleshooting Info and found the folder that it used for the profile (when I go to profile editor, there are 2 profiles listed in the new build - I verified that I was in the directory for the default profile). I then closed Thunderbird on the new PC.

The two computers are on the same network so I moved all the files from the old location to the new location via just drag and drop. Of note, I couldn't "go up 3 levels" on the original machine's directory as per the instructions because, well, there weren't 3 higher levels of directories - I just moved the Thunderbird to Thunderbird on the new PC.

When I open Thunderbird on the new PC, it still acts like it's a new installation, except I do have my Address book. I tried deleting the second profile it had created; no different. I tried creating a new profile and specifying a directory somewhere else (eg. C:\Program Data\Thunderbird) and moving the files there - no different. I tried copying (presumably inactive) Thunderbird folders from the old computer C:\Users\~\Roaming and \Local over to a similar location on the new PC - nothing changed.

Anybody have any other ideas of what I'm doing wrong? Thank you!

Hi, Not sure where to begin. Had issues w/mouse and decided to reimage. Copied all files from C:\Users\user\AppData\Roaming\Thunderbird. Now have no msgfilteres, folders in Local Folders, or an Address Book.

I used info from https://windowsloop.com/backup-restore-thunderbird/. Was this wrong? Where did I mess up?

Thanks

I need to copy my Thunderbird profile from my Linux partition to the MSWindows one. All the tutorials I've seen claim I can just let MSWin create it's AppData directories, exit TB, then copy my profile and profile.ini over to there.

Doesn't work. It ignores my existing profile and starts creating a new one, and wants me to enter a new account. have 10 different accounts, filters, and other customizations, and I am *NOT* going to manually recreate everythin

I have many years and email accounts on my old WIN10 workstation running all POP installations.

I have a new workstation with WIN11. Is it possible to install TB on my new workstation with my accounts installed as IMAP and keep the same folder configuration? I have many email folders and filters setup on the old workstation installation.

I would appreciate any installation recommendations. I've been using TB for years and would like to keep as much of the current configuration as possible.

I have everything I need from my old machine except my e-mail filters. If I copy the whole profile I will lose all of the sent messages and saved messages I have generated since I got Thunderbird up and running on my new machine.

Any user views on Betterbird over TB. The developer has done a great job and has one thing I do like and that is the ability to colour the highlighted email account rather than just the envelope icon. Experiences are appreciated so I can make the informed decision on which to use. Should I decide to use it how does one just port TB and its settings over to Betterbird.?

Thanks for views.

15.18.0 how to export to mobile from settings in the desktop thunderbird so i can use my android phone--if it will help, on my desktop there is no Export to mobile in settings!!!!!!!

I have a huge and vital archive of past emails in Thunderbird on my old Windows 10 PC. The hard drive containing the Thunderbird profile has now failed and I can't access its contents. I have a new Windows 11 PC and have installed Thunderbird on it. I thought I had backed up my Thunderbird profile on an external drive, so have copied this backup onto the new PC, and have tried to use Thunderbird's Import function, but I get an error message each time, saying 'import failed unexpectedly'. The backup I'm using was saved using a data backup program called Bvckup2 and consists of folders called '$Archive', 'Cache2', 'Safebrowsing' and 'StartupCache'. Am I doing something wrong? Is it possible I've been backing up the wrong thing? Am I going to have to send the failed hard drive to a data recovery specialist and hope that they can access it?

Hi,

I make extensive use of saved searches in Thunderbird and find them extremely useful. However, I have not found a way of exporting/importing the searches, so when I set up a new install I have to start from scratch with the search folders. This can take quite a while.

Does anybody know a way to do this?

I have tried using the profile folders, but they do not seem to save the search properties.

Any help would be very welcome.

I'm sure this is a really dumb question but I'm all set to unzip my profile backup into new machine. I see it named in the Quick Access window, but a double click on it brings an error message that I have to unzip it first. Clearly I'm learning both my laptop and win 11 at the same time, and I don't know where/how to unzip it. I'm confused, I hope my question isn't. Can anyone talk me thru getting it unzipped so I can import it into Tbird in new machine? Thanks, Stacy

With a new Thunderbird installation on Windows 10 Pro, I attempted to import my profile data from a Postbox on another machine. The process failed, citing two errors (see attached screen shot), EmptyDatabase Error: "blocklists/addons-bloomfilters" has not been synced yet Uncaught NS_ERROR_FILE_NO_DEVICE_SPACE: Component returned failure code: 0X805200010

The profile being imported is pretty large -- around 20Gb, so I wonder whether I have surpassed some capacity limit. I was doing this via the Import Tool on the Tools menu.

Porting my legacy mail folders is crucial. Any help would be greatly appreciated.
