Let's see if your data is still present.

Please go to "Help" (menu) > Troubleshooting information

Look down the left column of the first table until you see "Profiles". Click on "about:profiles" next to it.

The next screen will show you information about all your profiles. Identify the one that is in use. For each of the others, click on "Launch profile" and see if your data is there.

Hi Rick - thanks for your reply. I found data but if it is that what I had befopre is unclear top me. I exported my old data to an external drive but I cannot import them because the size oif the zip file is to large. Would be nice if you could give me an advice Thanks in advance Ralf

Hi Ralf,

Did you find and launch other profiles?

Hi Rick - I have saved the old Profil on an external drive but Thunderbird doesn´t import it. The Zip is to big and I don´t find it where I safed it - don`t know why Nothing makes sense to me

The easiest and best possible solution is finding the profile with your data using the method that I described. Have you used that method?

Hi Rick, I tried to create new profiles with my safed exported file - unfortunately it didn´t work. When I unzipped the Zip file a lot of files have been corrupted. Therefor I thing this is the problem (the exportation did not work correctly). Thank you for your assistance - but here it is very late and I have to go now. Have a nice day Ralf

I cannot help if you do not take my suggestions.
