Hi I'm curious if it's possible to use the same Thunderbird profile, stored on a NAS, form an Ubuntu based PC as well as from a Windows based one. Anybody out there with some experience?

Since one month, I now use a setup, where I have stored the Thunderbird Profile on my NAS and use it from different PC's under Windows. I would like to keep it like this, while switching one of the PC's to Ubuntu 11.10 (just done and it runs quite well) and use the same profile.

I share the exact profile I already had with WinXP before installing Ubuntu as a dual boot.

On Ubuntu, Thunderbird stores your profile.ini file in .thunderbird under Home (show hidden files enabled in nautilus to find it).

On WinXP, Thunderbird normally stores your profile.ini in c:\Documents and Settings\username\Application Data\Thunderbird\Profiles (Different versions of Windows store this folder in different places)

Before you start, make a complete copy of your profile folder, subfolders and their files in Windows as a backup.

To share your existing Windows profile with Ubuntu, navigate to your profile.ini on Windows, open it and make note of where the path to your profile folder is. Navigate to that path in Ubuntu and copy the complete path name (if you're using Nautilus, open a terminal and drag the path folder icon to the terminal to get the complete path name).

Once you've copied your complete path name, open the profile.ini in your Home .thunderbird folder and enter that as the "Path=" parameter. Change "IsRelative=1" to "IsRelative=0". Save and exit.

Now you can use your existing Windows Thunderbird profile in Ubuntu and back and forth.


You have to make sure your Windows partition with the profile is mounted before launching Thunderbird in Ubuntu.

You may also run into Thunderbird checking for add-on updates anytime you switch between your Windows and Ubuntu Thunderbird. Just let it run.

    Thanks James. On windows 7 the true profile folder is: '.../AppData/Roaming/Thunderbird/Profiles/...' (be careful with 'Roaming' folder b/c there is the same profile store in 'Local' folder that took me hours)

I experienced no problems when sharing my Thunderbird profile with Windows 7 on a dual-boot system.

Simply set up Ubuntu's Thunderbird like you would on Windows systems and you should be good to go (the configuration file is located in your home directory under ~/.thunderbird/profile.ini).

  • Sorry for late response. had to fix a hardware issue first. But now all works fine. Mounted the share from nas and switched with thunderbird profilemanager to the profile on the nas. Jan 15, 2012 at 20:15
