Review Outlook Calendar Privacy and Sharing Permissions

Check and adjust the staff mailbox calendar permissions to determine if details can be exposed, while keeping service privacy limitations in mind.

Microsoft Bookings is designed to protect user privacy by default. When syncing with a staff member's Outlook calendar, it intentionally obscures private appointment details to prevent unauthorized access to sensitive information.

If you need to display more details internally, you must modify the individual staff member's Outlook calendar sharing permissions. However, keep in mind that Exchange Online limitations may still restrict certain details from fully displaying within the Bookings interface.

1
Open Outlook Calendar

Have the affected staff member open their Outlook on the web or the desktop application and navigate to the Calendar view.

2
Access Sharing Permissions

Right-click on the specific calendar to be shared, and select 'Sharing and Permissions' or 'Calendar Permissions'.

3
Adjust Detail Visibility

Change the default permission level from 'Can view when I am busy' to 'Can view titles and locations' or 'Can view all details', depending on what your organizational policies allow.

4
Consult Microsoft Support for Tenant Settings

If details remain hidden despite permission changes, visit the Microsoft Bookings Community forum or contact Microsoft Support, as tenant-level Exchange configurations may be enforcing privacy rules.

Privacy Warning: Avoid exposing sensitive appointment information unnecessarily. Changing default calendar sharing permissions will affect how the user's calendar is viewed across the entire organization, not just in Bookings.

Frequently Asked Questions

Can I force Microsoft Bookings to show all appointment details to external customers?

No, Microsoft Bookings is strictly designed to protect privacy on the customer-facing booking page. It only reads staff availability (Free/Busy) to prevent double-booking, and it will never display internal staff meeting subjects or locations to external clients.

Why do some staff members show calendar details internally while others just show 'Busy'?

This variation occurs because individual users have different default sharing permissions set on their personal Outlook calendars. Users with permissions set to 'Can view titles and locations' will expose more data internally than those restricted to 'Can view when I am busy'.

Does changing Outlook calendar permissions update Bookings immediately?

Changes to Exchange Online and Outlook calendar sharing permissions may take several hours to fully sync and reflect within the Microsoft Bookings dashboard. If the status does not update, you may need to check tenant-level sharing policies in the Microsoft 365 admin center.
