Set up Thunderbird in IMAP (email)
This guide explains how to connect the email application Thunderbird to an email address hosted by Infomaniak.
Prerequisites
- Create the address within my kSuite or on a Service Mail (Service Mail only, or existing within a kSuite).
- Test the email password (do not confuse it with the one used to log in to the Infomaniak interface).
- Check on the Service Mail that the automatic diagnosis is correct.
Add the email address to the application
To configure the email application:
- Download the latest version of Thunderbird.
- Open the application.
- Check and complete the missing information by scrolling down if necessary.
- Click on Continue:
- The information found by Thunderbird about your email provider is displayed, leave IMAP selected:
- Click on Finish.
- In some cases, a warning about a certificate may appear. Simply confirm the security exception if the information mentions Infomaniak:
- The summary of your registration appears, click on Finish to add the address (or configure other services from there):
- There you go, 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 = 465 (with SSL)
- Username = the full & complete email address ( ? )
- Password = the one assigned to the email address you want to access ( ? )
- Authentication required for sending emails:
- It is activated 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 (= full & complete email address) and its password.

In case of trouble
⚠️ Infomaniak's email service is compatible with any application supporting IMAP/SMTP. For additional help, contact the support of the software used or a partner — also discover the role of the host.
There is no need to contact Infomaniak Support if your email address works well outside of the application. The most common error involves using an incorrect password. The troubleshooting guides help you resolve any potential issues:
