Question details

The user needs to resolve a SharePoint sync issue where the Events or Group Calendar web part states that a Microsoft 365 group no longer exists.

Fix Microsoft 365 Group Events Web Part Saying Group Does Not Exist

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: After modifying a Microsoft 365 group from private to public, the SharePoint site fails to display the group's calendar or events to non-members.
Observed behavior: The Events or Group Calendar web part displays an error indicating that the group does not exist. The group calendar also fails to load when adding it manually via Outlook on the web.

Before you start

Ensure you have site editor permissions on the SharePoint page and that the affected Microsoft 365 group has been successfully updated to 'Public' in the admin center for at least a few hours to allow for synchronization.

Solution 1Recommended

Remove and Re-add the Group Calendar Web Part

Refreshing the web part connection by completely removing and re-adding it is the most effective way to resolve caching and syncing issues after a group's privacy status changes.

SharePoint web parts can sometimes cache outdated group directory states. By removing the web part and republishing the page, you force SharePoint to fetch the latest group directory information from the Microsoft 365 backend.

Verify Group Privacy Status

Go to the Microsoft 365 admin center or Outlook on the web to confirm that the group is fully configured as Public.

Edit the SharePoint Page

Navigate to the SharePoint page displaying the web part error and click the 'Edit' button in the top right corner of the screen.

Delete the Affected Web Part

Select the broken Events or Group Calendar web part and click the 'Delete web part' (trash can) icon on the floating toolbar.

Re-add the Web Part

Hover over the section layout, click the '+' icon to add a new web part, search for 'Events' or 'Group Calendar', and select it to insert it back into the page.

Publish and Sync

Select the newly added web part, choose your group, and click 'Sync Calendar'. Finally, click 'Republish' at the top of the page to save your changes.

Remove and Re-add the Group Calendar Web Part

Propagation Time: It can occasionally take up to 24 hours for group privacy changes to fully propagate across all Microsoft 365 services.

Solution 2

Test Outlook Sync and Escalate to Microsoft Support

If the group remains unsearchable in SharePoint and Outlook on the web, there is likely a backend directory synchronization error requiring administrator intervention.

Frequently Asked Questions

Why does a Microsoft 365 group disappear after changing it from private to public?

Changing a group's privacy settings triggers a directory update in the Microsoft 365 backend. Occasionally, SharePoint web parts fail to sync this update immediately, caching the old state and causing them to report the group as non-existent until the web part is refreshed or directory sync completes.

How long does it take for Microsoft 365 group changes to take effect in SharePoint?

Privacy changes to a Microsoft 365 group typically take a few minutes to process, but depending on server load and caching, it can sometimes take up to 24 hours to fully propagate across connected services like SharePoint and Outlook.

Can non-members view events for a public Microsoft 365 group calendar?

Yes. Once a group is fully configured and recognized as public by the system, non-members should be able to freely view the group's event list and calendar using the SharePoint Events or Group Calendar web parts.
