Users need to adjust access permissions for a shared boardroom calendar to view specific meeting details instead of just a busy status.

How to Change Permissions for a Shared Boardroom Calendar in Outlook

Product: Microsoft Outlook
Device & OS: not provided
Scenario: A user or team needs to view more than just the availability status on a boardroom calendar, requiring visibility into the meeting subject, location, and organizer.
Observed behavior: Currently, users are only able to see the room's busy status without any of the specific meeting details or context.

Before you start

Ensure you are logged in as the calendar owner or have Microsoft 365 administrator privileges, as standard users cannot modify shared calendar permissions.

Solution 1Recommended

Modify Calendar Permissions via Outlook Properties

Use the calendar properties in Outlook to assign the correct permission levels to specific users or groups in your organization.

This method allows the current owner of the calendar to grant varied levels of access, such as 'Reviewer', which permits users to see full meeting details without allowing them to edit the calendar events.

Open Outlook Calendar

Launch your Microsoft Outlook application and navigate to the Calendar view from the bottom navigation bar.

Access Calendar Properties

In the left pane, right-click the shared boardroom calendar you want to modify and select 'Properties' from the context menu.

Open Permissions Tab

Click on the 'Permissions' tab located at the top of the Properties dialog box.

Add Users or Groups

Click the 'Add' button to search your organization's directory and select the required user or group that needs detailed access.

Assign Permission Level

Choose the appropriate permission level from the drop-down menu (e.g., select 'Reviewer' to allow them to read full details). Do not assign 'Owner' permissions unless the user requires full administrative control.

Apply Changes

Click 'Apply' and then 'OK' to save and enforce the new calendar permissions.

Modify Calendar Permissions via Outlook Properties

Former Employee Calendars: If the boardroom calendar was originally created by an employee who has since left the company, you will not have owner access. You must contact your Microsoft 365 administrator to take ownership or adjust the permissions centrally.

Solution 2

Request Permission Changes from a Microsoft 365 Administrator

If you do not have owner access to the boardroom calendar, you must contact your IT department to update the settings.

Frequently Asked Questions

Why can I only see 'Busy' instead of the meeting subject on a shared calendar?

Standard default permissions for shared boardroom calendars are often set to 'Free/Busy time' only for privacy and security reasons. The calendar owner must upgrade your permission level to 'Reviewer' or higher to display full meeting details.

Can I give myself Owner permissions if I am just a standard user?

No, standard users cannot assign themselves permissions for shared calendars. Only the current calendar owner or a designated Microsoft 365 administrator can grant or modify permission levels.

What should we do if the boardroom calendar owner has left the company?

If the calendar was created from a former employee's account, standard users cannot change its settings. A Microsoft 365 administrator must intervene using the Exchange Admin Center to assign a new active owner or to directly manage the shared calendar's permissions.
