My Thunderbird upgraded and my 1 of my 2 emails accounts stopped working due to a change in password security. (GMAIL). I saved my profile and unistalled TB and installed a older version hoping this would work . However after copying and paste my old profile over the new profile it stated "profile data were no longer compatible with the older version and to create a new profile".

I did not want to do this. So I kept my old profile uninstalled again and reinstalled the latest TB back again only to find when i copy and paste my old profile it now is no longer compatable with this version either .

How do i get my profile to work again? (even if it means just the one email account works).

re :My Thunderbird upgraded and my 1 of my 2 emails accounts stopped working due to a change in password security. (GMAIL). I saved my profile and unistalled TB and installed a older version hoping this would work . It will not work on any version because it is Gmail who made the changes. You will have to make the necessary changes - enable cookies in Thunderbird - set Authentication Method: OAuth for both incoming and outgoing important both are done at the same time - restart Thunderbird and enter password at prompt in the google window.


re :now is no longer compatable with this version either . What exactly have you got saved - it is just the 'profile name' folder or the entire 'Thunderbird' folder that contains the Profiles' folder?

In the saved 'profile name' folder there is a file called 'compatibility.ini' You can open it using a text editor like Notepad.

It will say something like this: [Compatibility] LastVersion=102.1.2_20220808204007/20220808204007 LastOSABI=WINNT_x86_64-msvc LastPlatformDir=C:\Program Files (x86)\Mozilla Thunderbird LastAppDir=C:\Program Files (x86)\Mozilla Thunderbird

What does your 'compatibility.ini' file say ? Post the info in this forum.

Hi many thanks for your reply. The profile i saved was the entire contents and I moved this to a back up folder. I tried to copy and paste over new profile FROM THE NEW INSTALL and it stated profile no longer compatible. Even though this was the newest version of TB.

[Compatibility] LastVersion=103.0.2_20220808125904/20220808125904 LastOSABI=WINNT_x86_64-msvc LastPlatformDir=C:\Program Files\Mozilla Firefox LastAppDir=C:\Program Files\Mozilla Firefox\browser

re :LastVersion=103.0.2

That is not the latest release. The latest release is version 102.1.2 https://www.thunderbird.net/en-US/thunderbird/all/

Actually you have not even posted Thunderbird information. You have gone into your FIREFOX Profile and posted info on Firefox.

You need to post the information for THUNDERBIRD
