...with Outlook

There is a priori no solution free to convert a .mbox file to an Outlook .pst e.g. However, following the above solution, completely free, you will get your emails from the .mbox archive on your Infomaniak address.

Free to you then no longer use Thunderbird but continue with Microsoft Outlook in IMAP since all your messages will have been stored on Infomaniak servers.
