Copy Yahoo email content to Infomaniak

Update 09/01/2026

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

 

Introduction

  • This operation does not affect the data already present in the destination address, nor the data in 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 handled: identical content will only be copied once.
  • Consult this other guide if you are looking for alternatives to this IMAP process.

 

Import your entire email history

 

1. Yahoo Prerequisites

  • To allow the Infomaniak assistant to access your Yahoo account, click on https://login.yahoo.com/account/security#other-apps and configure an application password, which is automatically generated by Yahoo.
  • You will need to copy it and then paste it in place of your password in the Infomaniak wizard for copying your emails; to generate it:
    1. Log in to your Yahoo account.
    2. Go to the Account Security tab.
    3. Click on Generate an app password:
    4. Choose Other app:
    5. Enter an app name, for example Infomaniak, and click on Generate:
    6. Copy the app password.

 

2. Infomaniak Prerequisites

 

3. Import email content from Yahoo 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 organisation; the import will be done to one of the email addresses associated with the Infomaniak Mail web interface (online service ksuite.infomaniak.com/mail) of the Infomaniak account you are using.
  3. Click on IMAP import.
  4. Click on one-time import.
  5. Fill in the field on the left with your source email address (the content of which you want to copy).
  6. Fill in the field on the right with the password for that same source email address (see requirements).
  7. Click on Confirm.
  8. If necessary, enter a second email address to be imported at the same time.
  9. Choose the email address from which to import emails; the drop-down menu lists the email addresses currently associated with your Infomaniak Web Mail interface (online service ksuite.infomaniak.com/mail) of the Infomaniak account you are logged into.
  10. After selecting the desired destination address from the list, click the blue Import emails button.
  11. The copy process has started. You can wait and view the result on the page once the import is complete, or close the window (the import will continue in the background, and progress can be tracked - see below).
  12. 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.
  13. Tracking is available in the settings of the destination email address, and only on the web app Mail (online service ksuite.infomaniak.com/mail).
  14. Tracking allows you to view the import history for the address in question.

 

4. Adjust application settings

If necessary, once you have completed the steps to ensure that the domain name associated with your email account 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 wizard.
