I FINALLY was able to find the original profile, all messages in the In Box, plus all folders with their contents. 'Lost' when our ISP's ' tech support person ' had me close/remove the TB POP3 account and create an IMAP account).

I need to merge the new small profile (In Box & with basic folders) into - onto the BIG, original, profile. So each time I get/check mail everything goes to, ends up in, the Thunderbird account containing all the OLD data and new working account.

Please remember I am barely TB literate, so start at 1 (A), not 27 (Z)& no tech words. Nor acronyms please.

Thanks! Remain in GOOD health, be WELL, 'n be

My Windows 11 laptop became corrupted and the os had to be reinstalled with Microsoft's help. In the midst of all this I did not think of backups sadly. After the restore I started to put my apps back on and without thinking, I installed Thunderbird. I realized immediately my mistake when I saw only new email and no local folders.

The Windows restore created a windows.old directory and I see my profile and configuration files in it. I want to use those old files but I don't know where to copy them exactly. There is some confusion on my part about where the startup is happening for Thunderbird. I really need to have access to all my old mail and local folders.

I'd appreciate any help in this matter. Thanks, Sue

Hi, I am extremely frustrated at my situation: I have a desktop (main computer), laptop and mobile phone all using Thunderbird, with a GMAIL account (IMAP) On my laptop I accidentally deleted the contents of the Archive (Thunderbird folder) and promptly ALL EMAILS AND HISTORY of emails wer LOST on said laptop. They subsequently disappeared on my mobile phone also. The delete action was also uploaded to GMAIL.com and I could not recover them there as it said I am using a different program. I then went on my desktop in offline mode and all my emails are there in Thunderbird (minus approx 5 days worth while the desktop remained offline (no big deal).

I have tried EVERYTHING to back up/export the profile from my desktop (while offline) and upload the mails onto my laptop to recover them and hopefully feed them to GMAIL. Nothing happens, they do not appear. I see all my emails within the thunderbird profile folder in a "IMAP.GMAIL.COM" folder but not in a "Mail" folder (is that relevant)? Is the laptop loading the emails then immediately deleting them, because it is syncing with GMAIL? I am so so lost. Please help. Thank you

Hi I had a systems crash and did a windows 10 reinstall. Windows created a folder windows.old. In the folder is users/"username"/appdata/local and roaming/thunderbird/profiles/ In the profiles folder for example I have a profile 34eu8280.2020. I transfered this folder to the newly installed thunderbird folder under roaming/thunderbird/profiles/ Next windows+r entered thunderbird-p. Create profile, entered 2020 as profile name, chose folder, entered 34u8280.2020, select folder, finish. In profile manager selected 2020, work offline, unchecked use selected profile without asking at startup, start thunderbird. Profile not showing up only account setup page.

At a lost as to how to proceed.

Any help would be appreciated in restoring profiles

It started with duplicate Archive and Drafts folders...so I checked TB help, and it gave me several suggestions, including going to my Profile folder and deleting duplicate folders from there. Everything seemed fine...until I realized that suddenly TB has NO emails later than 2022! I went in to Gmail to see if I could recover them...but they're all missing there as well. In my business account--also through Gmail, but managed through my domain name--not just my Inbox, but EVERYTHING is gone. It's as if I never existed.

This is extremely upsetting: I teach and have my own business, and losing all my emails is catastrophic.

Can someone please help?

I am in the process of transferring machines to a new machine for Win 11 At the same time, I have moved from an older version of Thunderbird to the latest version in the .esr release channel. I have now a new default profile with the thunderbird upgrade but want access to the data of the older profile. The older profile was running under an earlier version, release 140. Can I change the existing default profile to be the profile from the older thunderbird version and what are the implications

I want to install Thunderbird on my new computer (Windows 11) from my old (Windows 10). But I cannot open the downloaded version of Thunderbird - it keeps saying there is no profile. Of course there is no profile before I have installed it! I de-installed and re-installed the Thunderbird program, but it keeps saying the same thing. How can I open Thunderbird to install the profile?

hi, if i sync 2 t/bird installs which one will install its personal data on the other pc?. the same question also applies to my f/fox install if anyone knows

win 10 tb145.02

thanks very much if anyone knows

Hello. We changed from the ESR channel to the regular release channel today by installing Thunderbird v146.0 (regular release version) over the top of our existing installation (which was the ESR version). The installation went fine and everything appears to be working perfectly. My only question is why the name of the profile didn't change. It still has a name of 'xxxxxxxx.default-esr'. I would have thought that the name would be changed to 'xxxxxxxx.default-release'. Is this something we should change, or should it be left alone. Thank you very much for your assistance.

Windows 11 Thunderbird 137.0.1

ARRRGGGH! I've been using Thunderbird for over 20 years and it's doing something new and BAD:

Every time I open it since yesterday, it keeps adding additional inboxes (7), drafts boxes (3), sent boxes (2) and junk boxes (6) and trash boxes (2). I don't know how to get rid of all of the extra folders. My profile is backed up, I just tried deleting the program and installing the latest version and it opened the profile (I thought it'd open a default profile and then I could reinstall the "real" profile). What's happening and how can I fix it? No, this does not have anything to do with multiple email accounts and I haven't added any new ones. Please help!

I set up Thunderbird on Debain 13 OS "Trixie" and then migrated (or tried to) my profiles.ini and attendant email folders to Ubuntu 24.04. I have done this before between Linux and even Windows installs, copying the folders over. Usually that is all you need to do to migrate emails and 'set up'. However, migrating from Debian to Ubuntu causes issues, namely the import is rejected by TB. At first, I thought perhaps Debian is using a newer version of Thunderbird and Ubuntu uses an older version, so I upgraded Thunderbird to a newer version. Import of profiles and folders still crash. This is using the profile import tool in TB.

I have a lot of emails via IMAP and it takes a long time to set them up and about ten gigs worth of emails. Is there anything that can be done?

My C: drive is almost out of available memory and the following profile, jrqu4wd0.default-release, is the culprit. If I delete it what affect will it have on Thunderbird.

Systemordner Thunderbird umbenannt und neues Profil erstellt, alle E-Mail Konten neu integriert, Teste i.O.,

Aus alten Thunderbird Ordner war plötzlich keine Profilordner mehr vorhanden? Wieso plötzlich das? Sicherungen hatten leider auch keinen Profilordner von Thunderbird gesichert. Warum werden diese nicht gesichert?

Thunderbird switched automatic to Freedom. No possibility to avoid. All connections where lost. After input connection data mail where downloaded. But over 2000 old local stored mail are gone.

How to restore all old local mails, structure and archives?

I've been wanting to access Thunderbird's encryption ability on both my laptop and desktop. However, in setting up Tbird on my laptop I notice the user Profile should stay on one computer. Can I use the same Profile on more than one computer using the same source and password? Can I open a new profile on a second computer, even though I would have to use the same email source, a local provider? If not, is there an online source of email data I can use on Tbird on my laptop. Thanks much, Bruce Bartrug

Hello, i am currently woking on an issue inside of the latest version of thunderbird. We have the data file for thunderbird located on the desktop. It shows as 37gb of data. however when we try to open the data file from inside of thunderbird. We cannot see any of the information from the folder. If i go all the was into the data file directory and select sub folders, they will open inside of thunderbird and show correct data. however, when i set thunderbird to open the entire directory with its sub folders, the application does not display any of the sub folders or information from inside the folders. We have attempted to go into properties and repair the file from inside thunderbird. It shows as 0kb file inside of thunderbird. it shows as a 37gb folder on the desktop. Once again to clarify, i can access specific directories inside the data folder but not the data folder as a whole. Any support or suggestions would be greatly appreciated. Thanks You

I had to install Windows 11 fresh because of multiple issues with my PC (I upgraded from 10 to 11 6 months ago). I installed Thunderbird fresh, and am trying to get it to see my existing data with is on my D drive. I browsed to the folder in Account Settings, but it's not showing up. I have years of mail and don't want to lose it.

There are too many options in the help for me to know which are actually related to my situation. I thought I was ready to do this, but am surprised at how difficult it is compared to the last time I did something similar.

Any help, even just pointing me to the right place to look for help, is appreciated!

Thanks!

I have a Windows 10 machine, have been using Thunderbird and pobox for years.

In case you're not familiar with pobox, it is a mail forwarding service; I pay for an email address and they forward email to up to three servers. I've thereby kept the same email address for a very long time, just changed the address(es) they forward to as I change ISPs, etc. At some point I quit using my ISPs server for my email and just used the one at pobox.com. Pobox was purchased by Fastmail, and so they have some new server names; my old ones have continued to work on my current system.

I use POP3 instead of IMAP because I want the email on my machine, not on a server somewhere. I configured Thunderbird to do this long ago, and so I don't remember details; I've been depending on being able to extract any needed information from its configuration. I am confident I have the password correct; I can log into the web interface to my email, and the password works there.

My new machine is a dual-boot Win11/Ubuntu; my plan is to use the Ubuntu machine almost exclusively and only boot Win11 when necessary. I want to move email operations to the new Ubuntu machine.

I've read info on moving Thunderbird; I find the profiles on the source machine, move up two directory levels, find the equivalent directory on the new machine, copy with replace. I found:

c:\Users\name\AppData\Roaming\Thunderbird

on the Win10 machine, and

Home/snap/thunderbird/common/.thunderbird

on the Ubuntu machine, so I copied the files from the first to the second.

Having done that, when I start up Thunderbird, it displays a page saying "Set up your existing email address". If I do that, of course, it will create a new profile, and I still won't have the old one. I've tried creating it manually, but (a) I don't know how I will then merge it with an old profile and my thousands of email messages, and (b) I'm having trouble figuring out the incoming and outgoing server settings. I remember struggling with that back on Win7 or whenever it was.

Anyway. Anyone got suggestions on what might be going wrong here?

I assume there was an automatic update overnight. When I started Thunderbird this morning I was asked to enter our account information - which I did. However I had no Local files. I have a copy of the Thunderbird directory from two months ago - I copied this in to the Thunderbird directory in Local Apps/data but i still have no local files data. I have several years of saved emails that I want to keep available. Any Suggestions how I can resolve the problem.
