Configure New Outlook (Windows) in IMAP (email)

Update 03/19/2026

This guide explains how to connect the desktop app New Outlook (desktop application on Windows, replacing Windows Mail) to an email address hosted by Infomaniak.

 

Preamble

  • Although the emails themselves remain stored on the Infomaniak server, the experience in New Outlook is very integrated with the Microsoft cloud:
    • Some information from your account may be used by Microsoft for centralized management and better synchronization experience.
    • If you wish to have total and local control over your emails, consider using third-party email software/clients (such as Thunderbird for example) that allow for more direct storage.
  • The various services offered by Infomaniak are all compatible with the corresponding standard protocols (IMAP/SMTP for email, for example), therefore if you encounter a problem with third-party software, contact its publisher or a Partner and consult the support policy as well as article 11.9 of the Infomaniak Terms of Service.
