  4. Click on Add account:
  5. Enter the email address to connect.
  6. Click on the chevron Advanced options.
  7. Activate the checkbox to configure your account manually.
  8. Click on the Connect button:
  9. Click on IMAP:
  10. Enter the password for the email address you want to connect.
  11. Click the blue Connect button:

  14. Stay in or return to the File menu.
  15. Click on Account Settings to correct certain information that was added automatically but is incorrect.
  16. Click on Server Settings:
  17. Check and complete the missing information.

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 (need help?)
  • Password = the password generated for the email address you want to access (❓: my kSuite | Mail/kSuite Service).
  • Mandatory authentication for sending emails:
    • Enable this in the SMTP settings of your application.
    • Check "use the same settings as the incoming server" or, depending on the software/email client, 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

Check that the Mail Service is configured optimally.

You do not need to contact Infomaniak Support if your email address works correctly outside the application. The most common error is using an incorrect password. The troubleshooting guides will help you resolve any potential issues:

… and if your Outlook is no longer working after a change of your email password, please refer to this other guide.
