Thunderbird Community Forum

I was forced to erase my PC because it was infected with malware. I saved my Tbird profile to my HDD before erasing. I pasted the saved profile to %Appdata% >Thunderbird, copying 1,777 items. When I brought up Tbird, I got the Account Setup window, so I don't think the profile was actually there. What did I do wrong?

Not sure if I picked the correct topic for this...

I had to reinstall Windows 11 on my PC as the old copy was corrupt to the point I could not install updates, even with Microsoft's help. Before I made the plunge, I used Tools -> Export to create a zip file on my D:. After installing Thuderbird on the rebuilt copy, I went to Tools -> Import to recover everything.

About 19% in, I received error "Import failed unexpectedly, more information may be available in the Error Console." I found the Error Console but don't know how top proceed.

I have an image copy of my old installation. Can I simply locate the Thunderbird profile on the backup and restore it?

Hello fellow Thunderbirds,

I have been using Thunderbird for years and had thousands of emails in quite a few folders, with a shit-tonne of filters etc. My emails were running pretty well. I only use two addresses, but the folders help manage everything.

I just got a new computer last week. Prior to switching over to the new computer I read through the 'Export your Thunderbird Profile' help page, and the 'Move Thunderbird data to a new computer' pages. I've tried to follow all the info there (with a glitch, explained below).

I am using a Windows system and have gone from Win10 to Win11.

I have the following data:

• Mozilla Maintenance Service (in Program Files (x86) ).
• Mozilla Thunderbird (in Program Files (x86) )
• Thunderbird (In Users/Username/AppData/Local/Thunderbird) (Contains 'profile' and 'updates'

I tried to swap the above data into the same spots on the new computer, but alas, it's not working. I *may*, however, have fucked it up myself...

So... When I got the new computer, I immediately downloaded Firefox, but, alas, I entered my email's details before closing it down. It did download a few off the server, but only a day's worth (before I realised I screwed up).

As soon as I realised I'd mucked up, I uninstalled Thunderbird and deleted the files on the new computer (you know how when you download it doesn't always remove all the stuff, so I tried to do this).

I reinstalled Thunderbird, but closed it prior to loading the email addresses on (as instructed). I then transferred all the above data into the corresponding file areas on the new computer. However, everytime I try to run the program it just goes to the standard open screen (with the popup that prompts you to enter your email addresses and details into it - see image, below, in case I'm not explaining it right).

Anyway, I'd appreciate any help you might be able to give me as I'm desperate to get my emails running again and have access to all the saved emails which were in my system. Kindly. Larysa.

I tried the instructions at https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer, and watched the video. Copied and pasted exactly as instructed - nothing happened. Is it possible to transfer the data, including message filters and in-box folders, to the new PC? Old PC: version 115.18.0 esr (32-bit) - on Windows 7 New PC: version 153.0.3 (64-bit) - on Windows 11 Or is this data transfer impossible due to incompatibility of the different Thunderbird versions? Thanks. I also tried transferring the data from the old PC to a slightly newer laptop on Windows 10, utilising Thunderbird version 140.13.0 esr (32-bit). Nothing happened there either. Is it a lost cause? Do I just go ahead and create new message filters on the new PC and forget about trying to transfer the data and associated rules? Maybe that's the way to go for me. Thanks.

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.

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.

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.

I have followed the instructions for transferring the Thunderbird profile from my old computer to my new computer. However, the updates do not come across. I don’t get all of the folders that I created on the old computer. The email works fine.

My old Widows 10 computer died. All I have left of it is the last full Acronis 2020 backup. I have installed Thunderbird on my new Windows 11 computer and want to restore my Profile data from the backup. How do I find them? Have been searching for days and can't find anything like in your profiles help article.

If I can't recover the data can you at least send me my current license key?

I am trying to run Thunderbird on my laptop. I currently have it on my PC and my Phone. I just installed Thunderbird on my laptop and zipped my profile (60GB). I tried to open the zip file to make sure it was good. I could not open it, so i did not transfer it. I was looking for an easy way to get all my email accounts and passwords onto my Laptop. I would appreciate any help. Thanks! Kelly

I downloaded Thunderbird to my new machine, followed instructions to copy the Profile Folder from the old machine and pasted to the new machine. I didn't get a message asking whether I wanted to replace the data on the new machine. When I started Thunderbird, I am not seeing all the data I expected - no address book, only 200+ emails, no sent emails. What did I do wrong?

I have a window home computer that was upgraded from w10 to w11. I had to buy a new w11 machine at my vacation home because the old one was not upgradeable. I was successful in moving the profile from home to vacation home. But a month later I corrupted w11 on my new vacation machine while loading my earlier version of Adobe Photoshop from their instilling disk. W11 could not be repaired and I had to reinstall new w11 while keeping my files etc. This time Thunderbird would not let me move/use my old profile file. No mater what I tried!!

In the past, I've always moved the profile file "Thunderbird" in Appdata file to the new machine and renaming the installed Thunderbird file with XXX after it. It always worked in the past. My profile file is over 2mb. I've tried using all of the logical import options in this new instillations and only get error messages that it could not import the data and to look at the error console? Which I don't know where that is located. I will look for it in w11.

I think that the only difference (which I don't think should make a difference) is the directory name file difference after "users"

Any help would be much appreciated!!!!!!!

Hi all

I have the good C:drive out of a failed computer which is now unusable, with my profiles on for that PC. They go back a while and are useful for referring to. There is some important information there. How do I move them to the current PC? N.B. I have been using the current PC for a couple of weeks and already have quite a few emails on it which I would like to keep.

Suggestions please Thank you Keith

Someone suggested BetterBird would be better for me than Thunderbird, but I'm not sure it was the right decision. They said I should be able to just open Thunderbird and it should work as they have the same base code, but it doesn't. Any ideas? I have 8 email accounts, so I'd hate to start from scratch.

Hello. I have followed the instructions to copy the profile file to a drive and take it to the new computer so my Thunderbird will be the same on both laptops.

BUT I get a message that the profile file is not available. And I searched for the file by name and found nothing!

The actual message is attached.

I need to copy my emails to the new laptop.

My Thunderbird Desktop Version 140.9.0esr 64 bit. Help please. Installed Mobile T'bird on android mobile. On Desktop (MS Win11) T'Bird followed Settings - Export to Mobile - included all email accounts and Passwords - Export resulting in pop up box requesting Pin number. Don’t know a Pin nor can find a Pin nor find Settings - Accounts - Sign in options to change it.

The summary says it all. My T-bird acc't combines both outlook and gmail and now I wish to transfer the data into a new T-Bird (account?) on a new computer. I'm going from an ASUS Zenbook to a HP Omnibook AI.

Many thanks ! I should sign my name as "Totally Lost". Regards, Andre

I currently have the following:

Mozilla Thunderbird version 152.0.1 (64-bit) installed on a Windows 11 Pro computer. Within this installation are five E-Mail accounts configured and working.

I have selected Export for Mobile.

On Android (Samsung Galaxy S24 Ultra - 5G) One UI Version: 8.5 Android: 16 Kernel: 6.1.145-android14-11-33419968-abS928USQS6DZF2

Thunderbird Version: 20.0

I click on the Import Settings: Try to scan the QR Code from my laptop which says 1 of 2 QR Codes and I get nothing. No pop-ups, no approvals, it just sits there. Clicking done takes me back to the main screen.

Hallo, ich habe meine E-Mail-Konten in Thunderbird umgestellt von POP zu IMAP. Meine Filter-Einstellungen waren bisher gültig für "Lokale Ordner" (die Filter musste ich manuell starten) Wie kann ich die Filter-Einstellungen auf den Posteingang meiner IMAP-Konten kopieren/migrieren? Danke, und Grüße aus Berlin
