Update 10/08/2026

This guide explains how to connect the Apple Mail desktop app on macOS (MacBook Pro, Neo, etc.) to an email address hosted by Infomaniak.

 

Introduction

  • Instead of the manual configuration below, it is recommended to use the .mobileconfig configuration profiles provided by Apple (❓: help).

 

Manually add the email address to the application

 

Prerequisites

 

To configure the email application:

  1. Open the application.
    • If you have already configured an address, click on the Mail menu and then Add account:
  2. Enter the email address to associate.
  3. Click on Continue:
  4. Click on Other account:
  5. Enter the account name.
  6. Paste the password for the email address generated in the Infomaniak Manager (❓: help).
  7. Click the Connect button:
  8. Check and complete any missing information (❓: help).
  9. Check and complete any missing information (❓: help).
    • The red indication is normal because, at this stage, the application has not yet received the correct information about your account.

Recommended settings

  • Incoming IMAP server = mail.infomaniak.com
  • IMAP port = 993 (with SSL)
  • Outgoing SMTP server = mail.infomaniak.com
  • SMTP port & encryption protocol and command/method to activate this protocol: 587 + STARTTLS
  • Username = the complete email address (❓: help)
  • Password = the password generated for the email address you want to access (❓: help my kSuite | Mail Service/kSuite).
  • Mandatory authentication for sending emails:
    • Activate it in the SMTP settings of your application.
    • Check "use the same settings as the incoming server" or, depending on the software/email clients, enter a username (i.e., the complete email address) and the generated password.

Refer to this other guide if you are looking for information about other compatible email ports and protocols (SSL / TLS, for example).

 

In case of a problem

There is no need to contact Infomaniak Support if your email address works correctly outside the application. The most common error concerns the use of an incorrect password. The tool provided within Apple Mail can indicate this:

Create a new password from the Mail service (❓: help) and restart the configuration of your account in the email application.

The troubleshooting guides help you resolve any potential issues:

  • Remove any existing Apple configuration profiles (❓: help) related to your Infomaniak email before restarting the configuration.
  • Consult the solutions provided in this other guide regarding email in general.

If your Apple Mail is no longer working after a change of email password, please refer to this other guide.
