Fix SharePoint Calendar Web Part Not Showing Past Events
Question details
Past events are missing from the SharePoint calendar web part even though they are still actively stored in the background event list.

- Product
- SharePoint
- Device & OS
- not provided
- Scenario
- A user is viewing a SharePoint site page that includes a calendar web part and needs to reference past schedule entries.
- Observed behavior
- The events successfully remain in the SharePoint event list data but fail to display visually in the calendar web part.
Verify whether the events were accidentally deleted by navigating directly to Site Contents and viewing the raw Events list instead of the web part view.
Verify Calendar Web Part View Settings
Check if the calendar web part is using a filtered view that intentionally hides past events.
Often, SharePoint web parts default to views like 'Upcoming Events' which automatically filter out items with an end date that has already passed. Adjusting the list view settings can resolve the visibility issue without needing administrative support.
Navigate to the SharePoint page containing the calendar web part and click the 'Edit' button in the top-right corner of the page.
Click on the calendar web part to select it, then click the pencil icon (Edit web part) on the left side of the web part.
In the property pane on the right, check the 'View' dropdown. If it is set to 'Upcoming Events', change it to 'All Events' or a custom view that does not filter out past dates, then republish the page.

Contact Microsoft 365 Admin and Support
If the view settings are correct but past events still do not render, it may be a tenant-level configuration issue requiring Microsoft Support.

Frequently Asked Questions
Why do events automatically disappear from my SharePoint calendar?
This usually happens because the calendar web part is set to an 'Upcoming Events' view by default. This view contains a filter that automatically hides items once their end date has passed.
How can I check if my past events are actually deleted?
Go to your SharePoint site's 'Site Contents' (usually found via the gear icon), click on the 'Events' list, and look for your past entries. If they are there, the data is safe and the issue is only with the web part's display.
Can regular users open a Microsoft Support ticket for SharePoint issues?
Typically, only users with administrative privileges in Microsoft 365 can access the admin center to open official support requests with Microsoft Online Support. Regular users should contact their internal IT helpdesk.
