Answers for private customers

The Knowledge Base for private customers is already largely up to date. A few individual articles are currently being revised and will be updated shortly. We thank you for your understanding and look forward to providing you with the latest information on using mailbox.

Please note: The Knowledge Base has changed slightly. Categories have been adjusted and any URLs stored in the old Knowledge Base are no longer valid.

Shared Calendars

Shared calendars in the Family Account

The functions described in this article are available in all plans except the Light plan. If you have set up at least two Family Accounts, you can collaborate and view shared calendars, address book contacts, tasks, and files within this group.

Sharing in mailbox

Every share in mailbox — that is, everything that can be shared — is organized as a folder. The process of sharing address books, calendars, tasks, and file folders therefore always follows the same pattern.

Creating a calendar in the Family Account

To use a calendar within the Family Account, one member with a Family Account must first create a new calendar. To do this, open the mailbox Office, select the Calendar tab, click Add new calendar, and enter a suitable name.

Figure 2: Once calendars have been created, you can easily and conveniently add your family members.

Sharing a calendar

To make the newly created calendar available to other members of the group, open the calendar’s context menu (Figure 2) by clicking the icon with three horizontal lines and select Share / Permissions.


Figure 3: Share the newly created calendar with all family members.

In the dialog window Permissions for folder Family Calendar (Figure 3), you can add several or all members of your group. There are different roles available, which can be selected via the Details dropdown menu:

  • Author: permission to read, write, and delete
  • Editor: permission to read and write
  • Viewer: read-only access

Using the shared calendar

All members of the group who have been granted access to the shared calendar can find it in mailbox Office, under the Calendar tab, in the section Shared calendars.

Adding guests

The owner of a calendar can also add other users who are not part of the Family Account via the Add others field. Guests added in this way always receive read-only access to the shared calendar. After being invited, guests will receive an email with a link informing them that a folder has been shared with them — in this case, the Family Calendar.
