This guide explains how to connect the desktop app Microsoft 365 Outlook MSO (desktop application on Windows) to an email address hosted by Infomaniak.

Preamble

• 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 the publisher directly or a Partner and consult the support policy as well as article 11.9 of the Infomaniak Terms of Service.

Add the email address to the application

Prerequisites

• Create the email address in my kSuite or a Mail Service / kSuite.
• Create a password for the email address on the device you are going to configure.

To configure the email application:

1. Open the application.
2. Click on File.
3. Click on Add an account.
4. Enter the email address to be linked.
5. Click on Connect.
6. Choose IMAP:
   
7. Check and complete the missing information.
8. Click on Next.
9. Enter the password for your email address.
10. Your email address is now configured in the application.

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 = full & complete email address ( ? )
• Password = the one generated for the email address you want to access
• Authentication required to send emails:
  • It is activated in the SMTP settings of your application.
  • Check "use the same parameters as the incoming server" or according to the software/email clients, enter a username (= full & complete email address) and the generated password.

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

If you encounter any issues

Check that the Mail Service is configured optimally.

There is no need to contact Infomaniak Support if your email address works well outside the application. The most common error concerns the use of an incorrect password. The troubleshooting guides help you resolve any potential issues:

• Refer to the solutions provided in this other guide regarding email in general.
• This other guide is more specifically about Outlook.
