there was nothing in the trash nor on the serveur, and i didn't changed any settings
i used a backup (2 days old) to restore the mails.
my advice: before using this addon , check if the emails are in double in unified view AND in each folders. Do not use it if it's in double ONLY in unified

You likely did not lose anything, because, by default - the extension doesn't actually delete any messages: It only moves them to the trash. Please look in your trash folder, and you'll likely find all those messages.

To actually delete anything, you have to explicitly change a setting on the review dialog to perform a permanent deletion, then provide a second authorization when I warn you about deletion being permanent.
