Thunderbird Support Forum

I'm running Windows 10 Pro (64-bit). I have two different versions of Thunderbird installed on my system; one is installed in Program Files (64-bit version 125.0.0.0 dated 04/23/2024—old version) and the other is installed in Program Files (x86) (64-bit version 115.12.2.0 dated 06/25/2024—the current version). The shortcut icon on my desktop (which I never use) runs the older version located in the Program Files folder while the shortcut icon on my taskbar (and also the one in my Start menu) runs the updated version located in the Program Files (x86) folder.

As an aside, there are 21 .dll files in the Program Files (x86) folder (all starting with api-ms-win and dated 09/27/2023) while none of those files are in the Program Files folder.

FYI, I have been using Thunderbird on this PC for almost five years.

How do I fix this problem so that I have only the current version of Thunderbird run from the proper folder, Program Files?

I would like to know how I may transport Thunderbird from an old computer to a new without losing data. The old computer still is working. I do not have gmail, though I am considering going over to it.

I tried a few times to copy the thunderbird folder from my windows machine to my mac machine but every time I start Thunderbird after that it just creates a new profile folder and ignores the existing one which was already copied. Any help and insight will be greatly appreciate it!

OS: Windows 10 and Sonoma

TSO Host migrated all my email accounts to a different server. All my emails have stopped downloading to Thunderbird. I cannot find a way to configure my TSO Host email accounts since they upgraded their servers to Cpanel deluxe yesterday and neither can anyone at TSO Host.

All of a sudden I get: Thunderbird failed to find the settings for your email account

and so I have no access to my local folders where I store all my emails. Any ideas what has happened? And more importantly how I get back to my email interface on launch. Thanks in advance

Not sure of the best way to ask this. I am using TB 102.13 on a win 7 pro desktop machine.

Cox recently ported my email acount to Yahoo. There are about 100K emails in my cox inbox that were ported to yahoo. After modifying the server settings in TB so that I can use TB with the Yahoo server (I use POP settings), TB now sees all of the 100K emails as new, and each time I click the "get messages" button it starts downloading all of the 100K emails. I closed out of TB to stop the download.

I am told that in order for TB to only download actual new emails from the Yahoo server, I must let this process run. However, my official TB inbox uses about 30 filters to place incoming emails into the correct folders as they are downloaded.

All I want is to download the emails currently on the Yahoo server into a new created "dummy" inbox folder so that after the massive download, I can delete the folder and get back to being able to use TB appropriately. Can someone provide a 'how to" for doing this? TIA

The latest update of Thunderbird somehow made this message appear "This is an unsupported version of Thunderbird!!" (see attached picture). Is this a bug? I've checked the version on the homepage and it's the same that's running on my PC (Windows 11).

Greetings, recently our pc was attacked ,malware. A new windows program was installed. This resulted in some apps being deleted. One of which was the Firefox email. Inspite of many attempts to reinstate it I have had no success. There is great difficulty in finding what to do to reinstall. There are assumptions that I have particular information. Other than our 3 email addresses we do have any code numbers or passwords, as these to were also lost. As it has been several days since the "repair" the inability to access Firefox with historic emails is now creating a number of serious issues. I need urgent help in reinstalling our Firefox email. My inability to find that one person who I know can help is out there. The FAQ were of no help. The request how to reinstall Firefox does not appear to be a FAQ. Ross.

Hi, I love this email app. but now I starting to get this msg. What I need to do NOT to have this msg every time that I open the app. = Dear users, ThunderHTMLedit will no longer be hosted at addons.thunderbird.net. Please head to www.betterbird.eu/addons/ to install the new version. The extension “ThunderHTMLedit” is requesting to be uninstalled. What would you like to do? Thank you very much Pini

Hi,

I have six IMAP email accounts that will cease to exist in a few weeks when I don't renew the domain/hosting where they reside.

Most of these accounts include invoices for purchases, and serial numbers etc that I need to have access to after the accounts will die, so just being able to read them offline. Even down the track when I inevitably build a new PC, I'll still want to have access to theses messages offline.

What is best practice for archiving or backing up these so I can still read them in future? Is there a way to archive so that I can read them in other clients in future? or I can only archive in a way that will be Thunderbird only?

Also... how do I get Thunderbird to allow me to read the messages from these accounts, without checking for new messages on these accounts, which would give error popups every time?

I've never had to do this before, and when I've searched around the results seem super confusing.

Any help would be greatly appreciated.

In case its relevant, my current Thunderbird version is 115.12.1 and running latest update of Win 10.

I have been using Thunderbird a long time and I have emails going back about twenty years. This means that the built in import/export feature is hopeless. So I copied the entire Thunderbird folder to the new computer. I was able to transfer thousands of emails, but when I looked more closely I saw that my new Thunderbird only went back about 2 years. I would be very grateful if someone could tell a way to make it include the missing older emails.

I am trying to setup an Outlook account on Thunderbird and I get an error: "Unable to log in at server. Probably wrong configuration, username or password." I have an existing Outlook account which I am able to use on the Outlook app on Windows, the Android app and the web version on outlook.live.com I wish to have an e-mail client on my Linux Mint machine from which I can access my Outlook e-mails. To do so, I went to the 'Account Setup' page on Thunderbird and used these to set up my account: Your Full Name: <My Name> Email address: <email-id>@outlook.com Password: <My Microsoft password which I use to sign in to Outlook> Under Manual configuration: INCOMING SERVER Protocol: IMAP Hostname: outlook.office365.com Port: 993 Connection Security: SSL/TLS Authentication method: OAuth2 Username: <email-id>@outlook.com OUTGOING SERVER Hostname: smtp.office365.com Port: 587 Connection security: STARTTLS Authentication method: OAuth2 Username: <email-id>@outlook.com

I am sure that the password I am using is indeed the correct password. I still get an error as shown in the screenshot on the Account Setup tab. How do I resolve this issue? Thanks a lot!

I used the same password I have been using for a long time with my Verizon account and now I get this message: Sending of password for user k.machv@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later. I can open and download my email messages via AOL but it will not recognize my password to allow me to download my messages to Thunderbird.

When I migrated Thunderbird from a Windows environment to my new Apple Mac it did not migrate my local folders. Can someone explain the process?

I have the mozmsgs and sbd folders on my new Mac and have manually put them in the "local folders" directory but they are not recognised.

Regards Joe

Please advise what settings will work with Thunderbird for all NETWORK SOLUTIONS imap and POP accounts Also please advise the proper settings for all AOL accounts IMAP and POP

Hopefully this will reach Thunderbird support though I know Mozilla no longer supports this but the Thunderbird team does.

I would like to install Thunderbird on a MacBook Pro 2024 which I assume is running Os 14.5. It is not clear to me what version, if any, can be installed. I have used Thunderbird on Windows for many years but now wish to install it on this Mac.

Thanks,

 John

Do I install the 64bit option or 32bit ?? The installer gives me a choice.

After installation on the new M3 mac, I will be migrating my Thunderbird profile from a 2021 iMac that runs BigSur on Intel silicon.

I'm anticipating updating the iMac to Sonoma, but long experience has shown me that major s/w version upgrades are often very unfriendly to 3rd party s/w apps&data, so I wanted to get my tBird profile (all my mail history) working on the new Mac before doing the major upgrade on my iMac.

I was stupid and loaded down what I thought was an updated version, 115, of Thunderbird. Many of the folders with saved emails has dissapered. How can I get them back? Why is the number of saved emails shown on some of the folders. How to make the shown number to dissapear? How can I take away old emails in the infolder. In the previus version was that possible. I had to make all accounts once again. Shall it be that in an update? How can I get back the previous versin? I am not pleased with this new 115-version.
