Question details
The user wants to modify access permissions for a single user on a specific SharePoint calendar without altering their permissions across other calendars or lists.

- Product
- SharePoint
- Device & OS
- not provided
- Scenario
- Customizing access control for a specific shared calendar in SharePoint.
- Observed behavior
- The user needs a way to break inherited group permissions and assign unique access (such as read-only) to an individual for a single calendar.
Ensure you have Site Owner or Full Control permissions on the SharePoint site, as these privileges are required to modify list settings and break permission inheritance.
Break Inheritance and Assign Unique Permissions
Modify the calendar's list settings to stop inheriting permissions from the parent site, allowing you to set custom access for an individual user.
By default, all lists and calendars in SharePoint inherit permissions from the parent site. To change permissions for just one user on a single calendar, you must first break this inheritance.
Once inheritance is broken, you can safely edit, remove, or assign specific permission levels to individuals or groups for that calendar alone.
Navigate to the specific SharePoint calendar you want to modify. Click the gear icon (Settings) in the top right corner and select 'List Settings' from the dropdown menu.
On the List Settings page, locate the 'Permissions and Management' section. Click on the 'Permissions for this list' link.
In the ribbon menu at the top of the permissions page, click 'Stop Inheriting Permissions'. Confirm any prompts to create unique permissions for this calendar.
Select the checkbox next to the user's name or the group they belong to. Click 'Edit User Permissions' in the ribbon, choose the appropriate access level (such as 'Read'), and click OK. If they are in a broad group, you may need to remove them from that group and use 'Grant Permissions' to assign them access directly.

Frequently Asked Questions
Will changing permissions on one calendar affect other SharePoint lists?
No. Once you break inheritance for a specific calendar by selecting 'Stop Inheriting Permissions,' any subsequent changes made will only apply to that single calendar. The rest of your site will remain unaffected.
Can I hide a SharePoint calendar entirely from a specific user?
Yes. After stopping permission inheritance, select the specific user on the permissions page and click 'Remove User Permissions' in the ribbon. Without any permission level assigned, the calendar will not be visible to them.
How do I restore inherited permissions if I make a mistake?
Navigate back to the 'Permissions for this list' page for the calendar. In the top ribbon menu, click 'Delete unique permissions'. This will immediately erase your custom settings and restore the standard permissions inherited from the parent site.
