It sometimes becomes necessary to reinstall windows. Windows gives the option of saving data upon a reinstall. However, it destroys applications that were not part of the initial install. That means thunderbird must be reinstalled. However, if thunderbird is reinstalled, it destroys the thunderbird data that still resides on the computer. If thunderbird finds existing thunderbird data on the computer, it should inquire as to whether the user wishes for that data to be imported into the new installation OR saved as a separate file(s) OR overwritten. I just seem to have lost ten years of email data and my old addressbook. Have I missed something??

hi boitel, I think your are asking whether Thunderbird ("TB") keeps or removes "data" when TB is re-installed. TD saves personal information such as messages, passwords and user preferences in a set of files called a "profile", which is stored in a separate location from the Thunderbird program files, and is not destroyed when TB is re-installed. You may actually have more than one profile.

It's safe to re-install TB, but if you wish to be cautious, then backup your data. Data/Profiles can be found in Menu -> Help -> Troubleshooting Information -> Profile Directory -> Click on "Open Directory", this is the directory and probably names "someting-default" (see also below Support Article where you can find a note on the Windows folder where your Profile/Data should be located). TB should open with the default Profile once re-installed.

See also Support Article If I reinstall T-Bird do I lose my old e-mails and Update Thunderbird to the latest version (states "Simply download and install the latest version from the Thunderbird website, and Thunderbird will pick up your existing data.)

As as side note, if you have server type IMAP, then you will still have emails on your server (provided you have not deleted emails and emptied Trash), and these will be downloaded again to your local drive once you set up the account again.

All the best from Stockholm.
