Dear all, For some reasons (migration from another software some time ago, changes in configuration, etc.), I have a lot of duplicate messages in different TB accounts which eats my hard disk :) I know the [Remove Duplicate Message extension](https://addons.mozilla.org/en-US/thunderbird/addon/remove-duplicate-messages-alte/?src=search) but I wanted to know if it can detect duplicates between accounts. Thanks in advance, Mathieu
