This guide explains how to transfer to Infomaniak email addresses currently hosted by Microsoft, within Microsoft 365, using an IMAP import tool.

Introduction

• This operation does not affect data already present in the destination address or the source address.
• The entire external mailbox will be imported.
• Once the import process has started, it is no longer possible to interrupt it.
• Any duplicates will be managed: identical content will only be copied once.
• Please refer to this other guide if you are looking for alternatives to this IMAP process.

Import your entire email history

1. Microsoft Prerequisites

• Enable POP/IMAP/SMTP features that are disabled by default (need help?).

2. Infomaniak Prerequisites

• Have a Mail Service on your Infomaniak Manager.
• Have a quota of available addresses or adjust it beforehand if necessary.
• Ensure that the email is properly secured.
• Create one or more addresses on this Mail Service.
  • If you have many (10+) email addresses to create, please refer to this other guide regarding bulk creations.
• The destination email address must be linked to the user (= the Infomaniak account) you are using.

3. Import email content from Microsoft to Infomaniak

1. Click here to access the import tool (online service https://import-email.infomaniak.com).
2. If necessary, log in to your Infomaniak account for the relevant organization, as the import will be done to one of the email addresses linked to the Infomaniak Mail web interface (online service ksuite.infomaniak.com/mail) of the Infomaniak account you are using.
3. Click on the import via IMAP.
4. Click on the one-time import.
5. Fill in the field on the left with your source email address (whose content you want to copy).
6. Click on the "Connect with Microsoft" button that appears: 
   
   • Make sure you are connecting to the Microsoft account for which you want to copy the emails.
7. Confirm that you authorize the Infomaniak tool to connect to your account (automatic process).
8. Once you confirm the pop-up, choose the email address to which you want to import the emails. The drop-down menu lists the email addresses currently associated with your Infomaniak Web Mail interface (online service ksuite.infomaniak.com/mail) for the Infomaniak account you are logged into.
9. After selecting the desired destination address from the list, click the blue Import Emails button.
10. The copy process begins. You can wait and see the result on the page once the import is complete, or close the window (the import continues in the background, and progress can be tracked - see below).
11. A confirmation email will be automatically sent to all email addresses involved in the operation once the import is complete, indicating the number of messages copied.
12. A tracking feature is available in the settings of the destination email address, on the Web Mail app (online service ksuite.infomaniak.com/mail) only.
13. The tracking feature allows you to view the import history for the address in question.

4. Adjust application settings

As soon as you have taken the necessary steps to ensure that the domain name associated with your email works with Infomaniak, modify the settings of the email software/clients you use so that they connect correctly to the Infomaniak servers: follow the configuration assistant.
