Disable Group Calendar Options in List Settings

Disabling the Group Calendar options in the classic list settings is the most effective way to restore missing events and calendar overlays.

Modern SharePoint layouts do not always fully support classic calendar functions. The 'Group Calendar Options' setting can inadvertently hide older events and overlays when the calendar experience is updated.

1
Open Classic Settings

Access your SharePoint calendar and navigate to the classic view. Click the 'Settings' gear icon and select 'List settings'.

2
Access Title and Navigation

Under the General Settings column, click on 'List name, description and navigation'.

3
Disable Group Options

Locate the 'Group Calendar Options' section and set the toggle or radio button to 'No'.

4
Save Changes

Click 'Save' at the bottom of the page to apply your settings and return to the calendar.

Disable Group Calendar Options in List Settings
Events Restored: Your missing calendar events and overlays should now be visible again in the calendar view.

Frequently Asked Questions

Why do SharePoint calendar events disappear in the modern experience?

The modern SharePoint layout lacks full support for certain classic calendar features, causing rendering conflicts with legacy settings like Group Calendar Options.

Will changing the calendar back to the classic experience restore my events?

Reverting the experience setting alone often does not restore older events. You typically must manually disable the Group Calendar Options in the list settings to fix the issue.

Does disabling Group Calendar Options affect new calendar events?

No, disabling this option restores visibility for your older events and overlays without negatively impacting the display or creation of newly added events.
