Understanding the Synchronization Limits for Contacts & Calendar (macOS / iOS apps)
This guide details the specific features and limitations of Infomaniak contacts and calendars synchronization with native Apple applications (macOS and iOS), particularly for managing shared data.
Introduction
- Contacts and calendars hosted with Infomaniak can be synchronized with native Apple applications:
Contacts: synchronizing address books
The CardDAV protocol does not allow you to individually select the items to be synchronized; all data from the account is retrieved by default.
- Before adding a synchronization:

- All existing contacts on the macOS device
- Existing contacts on the user's Organization (named here AAlpha SA) in Infomaniak, including the Organization's directory (❓: help), which contains a group called North (in this case, it is a “circle” automatically created after setting up a Group (❓: help) in the Manager).
- The user's address book is called Lunchy.
- After adding a synchronization per macOS profile:

- All existing contacts on the macOS device (this displays the contacts that were already present, as well as the new contacts from the synchronization).
- Contacts from the synchronization (see point 2.d below).
- A downloaded profile contains the Infomaniak account user's name; this name will be used for the synchronized address book that will be displayed on the Apple side.
- In the example below, the user's name is Anna Alpha and the address book name is Lunchy; this is the user's name that will be displayed to describe the contacts on the Apple side.
- You can change the synchronization name in the Account Information:

- Existing contacts on the macOS device (those from point 1.a above — they remain local on macOS and are not synchronized — you need to move them if necessary).
- You can change the address book used by default for future contacts created on your device:

- You can change the address book used by default for future contacts created on your device:
- The user's address book is called Lunchy here — the equivalent of point 2.b above).
On iOS
New contacts created on iPhone are often saved locally ("On my iPhone"):
- You need to modify the default notebook in the device settings so that it is synchronized with the Infomaniak server.
Groups and lists
Grouping contacts into folders or lists does not synchronize bidirectionally. The list system does not use actual folders but category tags, which makes it impossible to retrieve contact groups.
- Lists created on Apple devices are not reflected on the Infomaniak server (but the contacts contained within them are):

- Groups configured in the web interface are not displayed in the Apple Contacts app (but the contacts they contain are):

- Tip: to delete a list created on the Apple side, select it and press the DEL./DELETE key on your keyboard.
Additional notebooks
The Contacts app does not support multiple address books for the same account:
- Only the default address book is synchronized.
- To access all your notebooks, using software such as Thunderbird is required.
Example of a new notebook on the Infomaniak side:
- The content of this second notebook is not synchronized:

- One solution to organize yourself in a similar way would be to create a group in Lunchy and add the 5 contacts to it:

Shared address books
An address book shared with another Infomaniak user will continue to be synchronized, including if contacts are added/edited via the shared access, as in this example of shared access with maximum permissions:
Conversely, receiving contact sharing from another Infomaniak user adds an additional address book. Synchronizing these additional contacts is therefore not possible (the same rule applies as presented in the “Additional address books” section above).
Calendar: displaying shared calendars
The CalDAV protocol does not allow you to individually select the items to be synchronized; all data from the account is retrieved,including calendars that you share and those to which you have been granted access/modification rights.:
If only your personal calendar is displayed, then try this procedure to enable additional calendars:
On macOS
- Open iCal / Calendar.
- Go to the Calendar menu > Settings (or Preferences).
- Go to the Accounts tab.
- Select the Infomaniak account and click on the Delegation tab.
- Check the shared calendars to display.
On iOS
- Open iCal / Calendar.
- Tap the Calendars button at the bottom of the screen.
- Check the shared calendars in the list.
Notifications (iOS)
You can enable or disable alerts for each specific calendar by tapping the ⓘ icon to the right of its name:
