Sync Contacts & Calendar (iOS apps) by CardDAV/CalDAV profile

Update 06/22/2026

This guide explains how to connect the Contacts and Calendar mobile apps to the contacts & calendars hosted by Infomaniak.

 

Introduction

  • Your iOS device will be automatically configured using .mobileconfig configuration profiles compatible with Apple, unlike a manual configuration.
  • It is possible to delete a configuration profile once it has been installed (scroll to the bottom of this page for instructions).
  • Infomaniak contacts & calendars are linked to your Infomaniak account; when you log in to ksuite.infomaniak.com/contacts or /calendar, you will likely need to perform two-factor authentication (2FA) during login.
    • In this case, an application password is required to establish synchronization between your device and Infomaniak tools.
    • But don't worry, creating such a password is offered as part of the configuration wizard.

 

Install a configuration profile

To do this:

  1. Click here to access the Infomaniak configuration tool (online service https://config.infomaniak.com) — log in if necessary to your Infomaniak account for the Organization where your services are managed.
  2. Choose to install the profile on this iOS device:
  3. Choose to synchronize contacts & calendars:
  4. Generate an application password dedicated to synchronization (in order to keep the usual 2FA login for your user account):
  5. Copy the generated application password (you will be asked for it when installing the Apple profile).
  6. Download the Apple profile:
  7. Allow the download on the device:
  8. Tap to close the message:
  9. Open the settings of the iOS device and tap on the banner at the top that informs you that a new profile has been downloaded:
  10. Tap Install:
  11. Enter your iOS device code as if you were unlocking it:
  12. Tap Install:
  13. Enter (or paste) the application password copied in step 5 above:

    and do this twice in a row (contacts + calendars):
  14. When the notification appears at the top, it's done:

If your iOS Contacts and Calendar applications were already open, you need to restart them. You will then see the information added by the synchronization:

*Why is it necessary to choose the guide version that exactly matches your macOS/iOS system version? Apple introduces sometimes subtle changes with each new version of its system. For example, a path on iOS 15
