Thunderbird Support Forum

Hello - I think I may have lost all my old emails. Also, I cannot set up a new copy of Thunderbird because it tells my that my configuration does not match, and I must supply the setting manually for imap and maybe other things - probably my settings for my local year-by-year archive since 1998 or thenabouts. Which I stupidly never made a copy of. I do have a copy of my latest default profile from 1st January 2024. Is there anyone who can help me, please ? Happy New Year from Sarah

I had a huge problem with M Outlook. In addition it has locked me out of my Office 365 package and I'm not getting help or support. Luckily I had backup completed before the problem. I changed to Thunderbird (using pop3), which I find very good. The back up is approx 8 GB but with many duplicates which I need to clean up. When I click import it seems to limit the file size to 2 GB. How can I import this backup file into Thunderbird to enable me to access the emails, clean up the many many duplicates and reduce the size? I await help, Thanks in advance

Good morning, I can't get to my stored emails. After reinstalling Windows, my profile could not merge with saved on my computer emails. I've moved profile folders to (...AppData\Roaming\Thunderbird\Profiles...) and inbox/sent/spam/trash .msf files to Thunderbird instalation folder. Unfortunatelly, I still don't have access to my saved emails. Could You please help me with this issue?

Hi,

Just checking if the Tools> Export is the correct way to download emails from Thunderbird. Not sure if the available articles on this topic are updated.

Thank you in advance!

Hi Just currently reinstalling windows and trying to import my old thunderbird files. i've exported the whole profile into a 12Gb zip but for some reason i cant extract it without errors. I've tried the latest winzip 28, beezip and 7zip and can only extract 4gb. 7zip listed these errors. screenshot: https://imgur.com/a/y4YjtYi

Are there any other apps i can use to extract this? thanks Z

I am replacing my old PC with a Mac that is running Sonoma. I’m a new Mac user so this is brand new to me. I have moved my Tbird profile from one PC to another. But moving to a Mac is brand new to me.

I have no idea where a Mac stores files or how to download to the right place.

Would you please walk me through, step by step, how to download my Tbird profile from my PC to my Mac so I will have all of my old email?

I have been using Tbird for decades and do not want to lose that email in my move to Mac.

Many many thanks in advance for your support.

Is there anyone "out there" with recent experience with S/MIME Entrust? I've migrated to a new laptop and imported my certificate. I've had people with whom I exchange encrypted emails on "old" laptop send me digitally signed emails, but I cannot get their certificates. Since Entrust has outsourced this product to a German company, I find they are not particularly helpful in this area. Can anyone step me through verifying steps and troubleshooting? Thank you

I tried to access a shared Gmail account via Thunderbird, let's say shared@gmail.com. I don't have a password for this account, but when I log in in the browser, Gmail knows it is a shared account and says "log in using another account" and then I can use personalmail@gmail.com to log in.

I tried this in Thunderbird by adding shared@gmail.com and then using personalmail@gmail.com as the OAuth2 option. I found some tutorials at university websites that use this, but all with Exchange and not Gmail. At first this didn't work; I got an "incoming server already exists" error. By using imap.googlemail.com I circumvented that and the account was added, but it showed the personalmail@gmail.com inbox, not the shared@gmail.com one.

Is there a way to make this work or is it simply not possible?

I'm trying to migrate old messages (stored under pop) in an outlook .pst.

choosing Tools, Import, then selecting Import from Outlook, immediately gives a "No Profile Found" above the import tool.

I'm not even clear if this is referring to a Thunderbird profile, an outlook profile, or possibly a file in an import directly somewhere?

anyone have suggestions?

Hello ! I have just had a new hard drive fitted to my old PC after a horrendous OneDrive incident. I have installed Thunderbird on my new drive but it does not seem to have loaded a Profiles folder in my AppData/Roaming/Thunderbird - just Adobe, Microsoft and Mozilla (Firefox). Can you tell me where else it might be so that I can paste in my old Thunderbird folder (with years and years of emails)  ?

All of a sudden 4-5 days ago I no longer can receive my Washington Post, only way is to scroll way down to last known one. What in blazes is going on at Tbird? Who is responsible? Is there anyone who can put it back at once? Yes my subscription is valid. If all of you refuse my small request, it means I have to PAY my own tech support, which is not fair of you. I don't care who messed it up; I only want my paper back NOW. I have noticed that Tbird is now run by volonteers; is that the problem? PLEASE help. Thank you

I am getting an error that "you have launched an older version of Thunderbird" Every time I try to open my email. I was using the latest beta version up to three days ago and the program got corrupted for some reason. I did try to install the latest beat online beat 2 .

Thanks, Al

Hello everyone,

Does anyone know how to import an outlook pst file?

I tried Local folders/Import/Import from Outlook, but Thunderbird says "No profile found".

I have set up a mozilla profile. Where to insert account details in a way Thuderbird recognises me and allows me to import outlook files - I would like to see my e-mails in Thunderbird, which I have previously received and sent off with Outlook.

Thank you all for your help in advance!

Have a wonderful year 2024!

Best, Farkas

Having trouble transferring local folders, address' and calendar to new computer. Have followed the Mozella instructions and the only folders transferred are Hold and Trash which are a fraction of the folders I have. What am I doing wrong?

I have installed Thunderbird on a new (Windows 11) lap-top. When I get to "Account setup>>Set up existing email address", and enter my password, I get the response "Configuration found in Mozilla ISP database", but when I click "Done," there is a long hesitation on "Checking Password", and finally the message pops up "Unable to log in at server. Probably wrong configuration, username, or password." I know my username and password are correct. All configurations appear to match those on my old lap-top. Server is att.net.

I prefer Thunderbird for composing, reading, and replying to emails, and have a decade's worth filed and stored locally on an older lap-top, which I will want to import.

サンダーバードを起動したときに、２回に１回ぐらいの頻度で、 左下に「**@gmail.comの全てのメールにメッセージをダウンロードしています」と表示され 今は2/13000のように、13,000通のメールがダウンロードされているように出ます。 2か月前から症状が出て、そのダウンロードが終わるまで、ゼロになるまで待機したことがあるのですが、 数日後にはまた同じように、１万通ほどのメッセージをダウンロードし始め、挙動が遅くなる状態です。 設定を色々触ってみました。自動削除をオンにしたり、自動受信ではなく手動の受信に変えたり。 gmail以外のアカウントも取得していますがそちらは特に変わったことはないです。 gmail自体が重い、メールが届きすげているのかと思い、googleアカウントから全てメールを削除したりも試みてみましたが状況は変わりません。 10年ほど使っていますが今までこのようなことはありませんでした…どこに問題があるのでしょう。

I have finally had it with version 115 and have downloaded version 102, but now states wrong profile!! How can I get around this problem? How to permanently stop TB from constantly trying to upgrade, and reinstalling the TERRIBLE 115 version??

At 82 I am too old for changes,just leave as it was and make me still happy with Thunderbird.
