I'm trying to help an elderly friend move from Eudora OSE to Thunderbird. I found this closed thread on the forum - and I want to know 'how to back up the Eudora OSE Profile' - or any other help you can give re migrating from Eudora OSE to Thunderbird. (She has thousands of old emails.)

The tech person said,

"May I suggest, back up your OSE Profile, and give it a try.

And the other replied: "I took the tech's suggestion Backed up Euroda files and simply installed Thunderbird VOILA ! When I launched Thunderbird it simply accessed the same files and file structure (and settinge/etc) as Eudora and I didn't have to do anything ... awesome !"

I recently installed Thunderbird on a new computer.I set it up to use my Yahoo account. It does receive emails sent to Yahoo but will not send. Every time i click SEND it asks for a password and always says it failed.

Under settings, there are 2 servers, IMAP and SMTP. Each has a different password, but at one point I made them the same. It does not matter because the outgoing server keeps changing its password to about 20 random letter and characters. At one point I copied these random characters into the clipboard and posted it in after it asked for a password...and it still FAILS.

I am using version 81.0.19 Until I get this fixed it is useless. An annoying thing is that each time I start Thunderbird, it asks for the password...on my previous pc it remembered it. Both machines are Windows 10. Can anyone help?

I've been happily using Thunderbird for email for many years. Recently, the gmail OAuth2 requirement has made my POP3 accounts quit working. Currently on 38.5 for Windows 10.

Following various posts, I've tried to convert two specific email accounts to imap, and things are not going well.

My primary email is already imap and works fine. I've tried multiple times to convert the other two, and my current state is I've deleted those two accounts entirely (via Account Actions). When I try to install Existing Account, I eventually get to the point where the server config seems correct, but hitting "Done" results in the above message. I'd be surprised if imap.gmail.com can only support one email address. The emails are named differently, and use different passwords. Imap is enabled via browser based access to both accounts.

Incoming server imap.gmail.com:993 Outgoing smtp.gmail.com:465

Hello, today I was surprised with a update ver.88 -> 89. It completely changed the look. Few weeks back it was similar with Thunderbird.

I hate this look. I want old look back - how to do this. I tried rollback to 88, but it ask to create new profile - after copying all content of profile it dose not work...

Is there a way to change look of 89 to look exactly like 88 ?

why why why .. again ..

Hi, I hope someone can help me.

I'm using Thunderbird Version 102.4.1 on a 7 year old laptop and it's getting to the end of life with numerous driver and non responding problems. Also, it is not compatible with Windows 11. I have linked 3 Yahoo mail and 4 Gmail accounts to Thunderbird on it and they work really well. All are IMAP server settings. I have just bought a new laptop, an early Black Friday deal, and hope to set it up the same as my existing one, so when the old one dies, as it's likely to, I will still have access to the same programmes and emails.

I know I can access Gmail emails direct on any device and they are always up to date - is that called synced? What I don't know is if all email accounts will be synced or the latest - if I use Thunderbird on both laptops. If I delete an email on one device will it be deleted on the other device.

If this is possible, do I download Thunderbird on the new laptop, then set up the accounts for each email and just enjoy from there, OR do I have to copy the profile from the old device to the new one.

I love browsing, streaming etc. but hate trying to get my PC set up or sorting out problems with it. Presume I know very little if you are replying. I have never had two working laptops before so never had to worry about syncing.

Hello at Mozilla,

I tried the archives first and have the exact set up but the same error like others have had keeps coming up, server error, password failed, try again later, etc, yet all settings are correct. I closed my online email program, restarted TB, same error.

I also used SM for a long time, like over a decade I think. Every few years when I change out my laptop, I go through this and it takes days to re set up my email to a client.

I really like having my emails in my computer to go through on/offline. It doesn't appear SM will be supported anymore so on to TB, which looks very similar.

Any ideas are appreciated, thanks!! ~Kirch

I've just got a new Win 11 PC and have followed the method to transfer all the emails in my Local folders to the new PC. TBH I've tried many of the methods without success.

I've copied the folders from the relevant directory on the old Win 10 PC onto a USB. With TB closed on the new PC I've copied the folders from the USB to a new Folder in Local Folders directory.

When I open TB, of the ~7,500 emails I copy, only 282 appear

I've tried this many times now with no luck What am I doing wrong please?

I updated to ver. 102.1.2 from withing Tbird but had to roll back to version 91.12.0 because new messages showed only the Subject but not message body. Has this been fixed yet?

The Mac Mail client I've used for years is falling apart under Big Sur. I mentioned this to a friend and he reminded me of Thunderbird - I had used it MANY years ago. I've recently converted to Firefox so this seemed like something to explore.

I downloaded it and entered the account info for my personal email via Sonic.net (POP) and work (via gmail). I was pleased to see the emails syncing for both accounts.

Until a couple of hours later when I noted that ALL my mail was gone on my laptop running Mail. I traced this to a DEFAULT setting of removing the emails from the server.

Please insert an expletive here.

You've got to be kidding me - this is the default? Is there ANY way I can get those emails back on the server? Luckily my work account still has the emails on the server.

I hope you can help.

I've just upgraded, automatically, to the latest Thunderbird. On opening nothing exists, no address book, no folders or emails, nothing. No idea what's happened as this was an automatic process. I have found a profile folder where it should be but I'm not confident to start trying to change things as I'm happy to find what looks like the data but don't want to do anything that might affect it. Any help? As far as I'm aware my install is 'normal'.

tried upgrading/clean install, 32b and 64b, version 102 when came out and now 102.5.0 always end up with a non-usable , no folders (sent, trash etc) top right menu does not open either had to go back with system restore and today even reinstall old version

does the new version require any windows component that the old one did not? (i may have disabled some features i dont need). all other programs work perfectly.

any advice will be appreciated, thanks

I have had this issue before and uninstalling and reinstalling has fixed it in the past. Today when I opened firefox it prompted me to update , which I did without thinking. Subsequently, it stopped working. I have tried: restarting my PC, running in troubleshooting mode( it wouldn't even open when I tried this), uninstalling and reinstalling using the internet installer, uninstalling and reinstalling using the offline installer ( tried on multiple hard drives, so I don't think hardware failure is the issue), installing an older version of fire fox, and installing the 32 bit version instead of the 64 bit version. The attached images show what displays upon trying to launch firefox. nothing loads, not typing an address into the search bar, not clicking on a bookmark, the only UI element that will display is the 3 horizontal line setting menu.

Yesterday my firefox updated to version 96.0. It changed to screen to dark theme. I prefer the light theme and need help to change it back. Thanks

Email me at [email]@Hotmail.com.

When I try using the box to align fields (First Name, Last Name, etc.) I get a couple of lines to match up and then after that as I continue they all start to float around. What is the method for setting the left side with the right side of the box? I'm importing my address box from Gmail.

Hi All, I would like to change my laptop, so I would like to export my saved passwords, but I am unable to see such option to export all saved passwords. Please help me Asap.

I have used Eudora for years, about 20 or more. Now I find myself with a dilemma. A secure email program I signed up for must have ports assigned to incoming and outgoing servers. Alas, not possible with Eudora, but possible with Thunderbird.

However, after reading several of the threads of migrating to Thunderbird from Eudora, it appears to be problematic--new addons, missing mailboxes, etc. It's hard to tell whether that's the norm or the exception. One of the threads I read was https://support.mozilla.org/en-US/questions/1228297 "Migrate Eudora mail to Thunderbird mail", which suggests starting with Thunderbird 17.0. That thread is from 3-1/2 years ago. Is this still the best way to migrate? Or is one of the Thunderbird migration tools a better and safer option.

I have literally thousands of saved emails and dozens of separate mailboxes and I don't want to lose them.

I have been able to move my profiles and Thunderbird is working correctly. However, I cannot find/get my local folders (the TB equivalent of a PST file) to move to my new system so I can still have access to all those save emails and records. I have searched here and cannot find a clear answer on how to get those files moved. Any help (please dub it down a little for me :) is greatly appreciated. Thank you.

Hi, new updates on Version 98.0.1 quite a hassle for me. It auto-download all my files even when I just want to view. Is there any other way to disable this feature? I opened Setting>Download but there is no disable button or checkbox for that. Please help me. Thank you in advance.

Happy New Year all volunteers, In W10, after crash all my applications, and their setup/data got wiped out. Tbird worked before like charm. Then it was a new installation 2 years ago. I moved mail data from Vista Mail on a Toshiba PC to my then new GP PC, with W10. Now, I have to re-install all the apps, and try to import/collect data. Luckily, my Vista PC is still working, so I can recover things from there. So, in Vista Mail i exported contacts, tried .csv, and .vcf. Csv seemed to work, however the import in Address Book was not functional. The names and e-mail addresses were mixed up. Then, I tried .vcf: with a single contact it works fine, but not with a list of .vcf files. Then, I found the advice to create one .vcf file for all contacts via copy *.vcx merged.vcf. The file got created, and looks fine. The windows contact too can open it, one-by-one. Windows10 Mail can handle it also. But, when I try to import this in TB I got as far as START import. Then, the message "Import failed unexpectedly, more information may be available in the Error Console". I do not see error console, and more hints. I must tell, extracting contacts from GMAIL works too. But, unfortunately I do not have set up gmail so that it saved all contacts upon referencing, so I just have a subset of contacts there... Do you guys have a working solution, or is this a new chart again ? By the way, the TB version is the newest one, a guess it is 102. Cheers, Zoltan
