Copy external email content to Infomaniak using MBOX

Update 09/01/2026

This guide explains how to copy the content of one or more external email addresses to Infomaniak (all email messages, folders, subfolders, in short, the entire structure of your third-party email account) to one of your existing Infomaniak addresses (regardless of the Mail service), thanks to the MBOX import tool offered by Infomaniak.

 

Introduction

  • This is the ideal procedure when switching hosting providers or restoring old messages that are still stored elsewhere.
  • Once the import process has started, it is no longer possible to interrupt it.
  • Any potential duplicates are handled: identical content will only be copied once.
