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

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

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 was finally forced to upgrade from win7 (which worked) to win 10 (me no likey) because of a required program which would not even install on win7. After the upgrade, which obliterated my hard drive of several important things, I am reinstalling TB. I always used an NAS directory for Thunderbird, and have email records going back nearly twenty years. I installed TB 115 and have tried several ways to get it to recognize my profile directory on the NAS to no avail. I tried copying data into the default directory the 115 install is looking at. The about:profiles shows it is looking in the correct directory, it produces a parent.lock file in that directory when I run the program. It does not give me my email, or contacts. I do not use the calendar or to-do lists.

My system is an AMD K6-6400K with 16 GB and a 500 GB drive. Though programs are loaded on the drive ALL data is stored in an NAS. There is about 375 GB available on the C drive.

I have used the cmd line to pull up profile manager, added a profile, pointed it to the data that is on the NAS, a parent lock file is created there too but it shows me no mail.

I have edited the profiles.ini file manually to have the program look at the directories, both the NAS and a local directory which has had the old files entered. Neither worked.

I tried opening TB and creating a new profile and pre-loading the info there, nothing. I've been at this for days now. I have uninstalled and removed manually all TB folders and reinstalled older versions to give that a go but without effect. I am no Luddite (Many years ago I owned a system integration, assembly and install company doing networking for the military as a civilian contractor.) but someone has to explain this to me like I am a five year old. There is no reason having my email back should be this difficult!

PLEASE give me a hand?

My TB directory appears in C:\Users\owner\AppData\Roaming\Thunderbird My old data folder was on a network drive at M:\Users\owner\AppData\Roaming\Thunderbird\profiles\k5zbs5az.default When I manually enter the M: address in the profiles.ini file, it "corrects" it to C:\Users\owner\AppData\Roaming\Thunderbird\ even though the switch 'relative' is off.

[Profile1] Name=default IsRelative=1 Path=Profiles/zpfeu8eu.default Default=1

[Profile0] Name=default-beta IsRelative=0 Path=C:\Users\owner\AppData\Roaming\Thunderbird

[General] StartWithLastProfile=0 Version=2

[Install5D388C1349709B37] Default=C:\Users\owner\AppData\Roaming\Thunderbird Locked=1

Running the Mozilla application with a specific profile using command line arguments brings up the program but no mail. It creates a lock file in the correct directory, but no joy.

I get no pop up error messages.
