This guide explains how to import emails contained in a MBOX format archive into an Infomaniak mail address.

Prerequisites

• Have a valid and functional email address with Infomaniak.
• Have an archive of your previous email in .mbox format.

Importing emails in MBOX format...

… with Thunderbird

Install Thunderbird and configure the Infomaniak address in IMAP. Then, to add support for importing MBOX files:

1. Open Thunderbird.
2. Click on the Tools menu.
3. Click on Add-ons and Themes.
4. Search for the extension ImportExportTools:
   
5. Click the button to install the extension ImportExportTools NG.
6. Confirm the addition of the extension on Thunderbird:
   
7. Create a new folder by right-clicking in the local part of your account's folder structure:
   
8. Right-click on this new folder and choose to import a mbox file from the new menu of the ImportExportTools NG extension:
   
9. Select the .mbox file from your hard drive and import it.
10. The import of your emails is done in the local folder.
11. This local folder can be moved to the main directory to be synchronized with the Infomaniak server via IMAP:
    
12. Emails are sent to the server and you can find your content if you check your mailbox from another system, such as the Web app **Mail** Infomaniak (online service mail.infomaniak.com) for example (or even Apple Mail or Microsoft Outlook - read below):
    

… with Outlook

There is no free solution available to convert a .mbox file to a .pst Outlook file for example. However, by following the solution above, which is entirely free, you will be able to access your emails from the .mbox archive on your Infomaniak address.

You can then choose to stop using Thunderbird and continue with Microsoft Outlook via IMAP since all your messages will have been stored on the Infomaniak servers.
