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 Categories have been adjusted and any URLs stored in the old Knowledge Base are no longer valid.

Sharing Calendars and Address Books

In mailbox, you can share personal calendars and address books with other people — both internally with other mailbox users and externally. This feature is especially useful for family accounts where multiple people want to access the same calendar or contact list. Sharing is done using standardized formats like vCard (for contacts) or iCal (for calendars), which are supported by many applications.

  4. Click the three-dot menu next to the address book name and select Share / Permissions.
  5. In the sharing dialog, choose whether access should be restricted to invited users or open to anyone with the link.
  6. Copy the sharing link and send it to the intended person or paste it into an application.
  7. Alternatively, you can export individual contacts by selecting them and using the menu to save them as a vCard (.vcf file) for sharing.

Note: The global address book of your account is read-only and cannot be shared.

Technical Notes and Security​

  • Read-only Access: All shared calendars and address books are shared with read-only permissions. This means external users can view the content but cannot edit it.

  • Compatibility: Make sure that recipients are using applications that support vCard or iCal. These are standard formats and work with most common calendar and contact applications.

  • Privacy: Anyone with the sharing link can access the shared content. Therefore, only share the link with trusted individuals.

  1. Log in to your mailbox account and open mailbox Office.
  2. Go to the Address Book section.
  3. In the left-hand column, locate the address book you want to share.
  4. Click the three-dot menu next to the address book name and select Share / Permissions.
  5. In the sharing dialog, choose whether access should be limited to invited users or open to anyone with the link.

To use this as an iCal calendar link (e.g., in Thunderbird), simply append ?ical=true to the end of the URL.
