This guide explains how to connect Microsoft 365 to an email address hosted by Infomaniak.

Introduction

• Infomaniak email addresses cannot be added directly to Outlook online from a browser using a personal Microsoft account
  • Indeed, Microsoft no longer allows adding an external address via IMAP to outlook.live.com.
  • Only the Microsoft mailbox linked to the connected account (address @outlook.fr, @outlook.com, @hotmail, etc.) can be displayed there.
  • “Microsoft 365” is primarily a subscription; Microsoft has removed the function for connected accounts in Outlook.com, and the equivalent function in Outlook on the web has also been removed.
• To view an Infomaniak address with Outlook,you must therefore install the Outlook app or use other IMAP-compatible email software/client.
