Thunderbird Community Forum

Hello, I hope you are doing well.

I spent several hours yesterday and today moving all my Gmail messages to my Yahoo account in Thunderbird on Windows 11 25H2 Home in the United States.

I expected my emails to appear in my account when I logged into the Yahoo Mail site. Instead, my account has no messages at all.

How can I correct this? I don't want to lose all my emails, I want them in Yahoo instead.

NOTE: Please change my email address to JAL1862@yahoo. I am closing my Gmail account by the end of the day on September 30.

What do I have to do to get help in this Forum? This is the second time I've posted a Question seeking help, and yet again it is being ignored. Do I have join some secret clique or group? If so please tell me?

Due to issues with upgrading from Ubuntu 24.04.1 to 26.04.1, I decided to just start from scratch with a new clean install.

After finalising the install, I copied across my Thunderbird data to the new partition, merging directories as the data copied across. But, somewhere in the transfer I lost about the last two years emails, with only emails up until 12/24 being available.

There are a lot a important emails I need to recover, and I'm guessing they're still on my PC, in the old partition, and I desperately need help to recover them.

Dear Sir or Madam, I downloaded and installed Thunderbird. Then, I wanted to import my emails and email addresses from my Outlook 2019 (as part of Office 2019). The emails did transfer. Not sure if my email addresses (called contacts?) transferred. At the end of these transfers, I no longer had Office 2019. My taskbar icons for Word, Excel, and Outlook gone. The only "Outlook" I now had was the "Outlook app." Office 2019 gone. Apparently, it got replaced with Office 365. Not at all what I wanted.

Did I so something wrong? Is this something to be expected?

Thank you.

I'm having trouble with my provider when trying to send a message. I thought I'd save a draft and send it later -- after my provider problem is resolved. After "Save" ing it, my draft folder is empty. Tried this twice... same result.

Second issue: I am trying to convert to Linux. Currently I keep all my Thunderbird stuff on an encrypted disk (Dekart Prvdsk). while I can mount this drive and access this from within applications, PrvDsk will not allow me to copy the files to an unencrypted disk. Is there any way (like a tool) that I can use to export all my folders (everything in "Profiles\2kbxyxpa.default-release\Mail\shastaemail.com," not just the profile?

Hello, I retired in June. I asked my employer to allow me to archive my emails before they deactivated my work account. The Director of IT has been very helpful in recommending various apps that can do that. One was enormously expensive. One archived all my emails together (29K) and it is very difficult to locate one separately. The IT Director has also recommended Thunderbird. I have downloaded it but am having difficulty using it. I have saved all my emails using Google Takeout and the emails are saved in an mbox format. If you could help me get started with making sure the Thunderbird default settings are correct, placing the emails into Thunderbird and showing me how to access certain emails (and delete ones I don't need to save), I would greatly appreciate it.

Thank you, Susan Hook

Outlook for Mac will no longer support local folders sometime in October 2026. I need to move my local folders to Thunderbird. I don't see any options for doing this.

Hello people, I've just upgraded my Thinderbird because my inbox didn't load on opening the programme. I guess I have made a huge mistake somewhere in the process, because my whole archive has disappeared. I very much hope it still exists somewhere and that I will be able to restore it with your help. Thanking you in advance, Nele Ysebaert, Amsterdam

Greetings,

I perform a daily thumb drive backup of Thunderbird in the event that my PC crashes (which it has) so I don't loose emails and contacts. I'm aware of two methods to do this. I've tried both, and one method saves more file folders than the other. My question is: Which is correct to use?

One method is described here: https://support.mozilla.org/en-US/kb/thunderbird-export The other method is accessed from the main page of Thunderbird: Import/Export > Backup, select OK and then the location and folder where you want the data to be transferred.

The first method captures four main folders and other files listed below them. The second method captures ten folders and all of the same files as in the first method.

Because they are different, I'm unsure of which to use and, additionally, why would two methods be offered?

Thank you in advance for your comments and advice.

Thunderbird Mail Accounts Not Imported from 5 GB Backup

Hi everyone,

I’m trying to restore my Thunderbird setup from a 5 GB backup/export file.

Thunderbird already recommended that I manually extract the backup file and then import the extracted folder. I followed these instructions, but after importing the folder, none of my mail accounts are restored.

The backup file is about 5 GB in size, so I assume the data is there, but Thunderbird does not recognize or restore the email accounts.

Has anyone experienced this issue? How can I properly restore the mail accounts and their emails from this backup?

Any help would be greatly appreciated. Thanks!

Please help me log on to Thunderbird in order to open a mailbox file sent to me containing email messages to and from the church I worked for until the June 28, that were in an account they closed before I could archive materials in it.

My computer crashed and I cannot retrieve my e-mail and I don't remember how to get to it. Had it for many years and just had an icon on the computer so I don't remember anything about it except Thunderbird. The e-mail address is [redacted from public] @metrocast.net Can you please help me find it?

Hello.. I was deleteing some mail in my inbox and then the program burped and said there is no more space. I tried to download new mail and got the no space message when I noticed that the whole inbox was gone.

I managed to recover the inbox folder and now I'm trying to put it back into the email program through windows explorer but when I try to paste it into the folder with the index.msf file I get the error that I don't have permission and must have administrative permission to copy the folder. I went through the properties and security tab and gave "everyone" full permission for the inbox, but it still won't let me past the folder back where it belongs.

How can I get the Inbox with it's mail back into my Thunderbird program?....

I'm using a Lenovo laptop with Windows 11.

thanks, David

None of the methods listed, either via Thunderbird or on the Internet in general work. Or, if they are supposed to work, the directions are not complete or accurate.

I'm trying to move stored emails from Outlook 2019 POP3 Windows10 32-bit into your latest Thunderbird. NO luck. Yes, I get a .CSV file from Outlook, and change it to MS-DOS version, then nothing. Similar with names/address. There is a lot of talk about having to use EML as the transfer medium--but, Outlook can't create EML. Worse, within Thunderbird, even with you Import/ExportTools NG add-on, there is no commone EML linkage to make the transfers work. SO...where is a guaranteed method to make these transfers work?

As of now Thunderbird is just a crude mail client--I can receive emails, I can send emails (but have to manually enter the address). None of the old Outlook emails are available. None of the old Outlook addresses are available.

Don't mean to be so cynical; but, I'm so tired of software making promises and then not delivering.
