Question details

The user needs to retrieve a complete list of calendar events, including recurring ones, within a specific date range using the Microsoft Graph API without missing any entries due to pagination.

How to Retrieve All Calendar Events with Microsoft Graph API

Product: Microsoft Graph API
Device & OS: not provided
Scenario: Querying calendar events via API and ensuring all recurring events within a date range are fully retrieved.
Observed behavior: Using calendarView expands recurring events, but the API paginates results, which might result in incomplete data if the pagination link is not followed.

Before you start

Ensure you have an active Microsoft Graph access token with the appropriate Calendar.Read or Calendar.ReadWrite permissions granted for the target mailbox.

Solution 1Recommended

Use the calendarView Endpoint with Pagination Handling

Utilize the calendarView endpoint with ISO 8601 timestamps and handle pagination via the @odata.nextLink property to ensure all events are retrieved.

The calendarView endpoint automatically expands recurring events into individual occurrences within your specified date range. Because the results are paginated, you must continue requesting the next set of data until all pages are consumed.

Construct the API GET Request

Set up the endpoint using GET https://graph.microsoft.com/v1.0/me/calendarView.

Define Start and End Times

Append the startDateTime and endDateTime parameters using the ISO 8601 format (e.g., ?startDateTime=2025-01-01T00:00:00Z&endDateTime=2025-12-31T23:59:59Z).

Maximize Page Size

Add &$top=1000 to the query string to retrieve up to 1000 events per response page.

Process Pagination with @odata.nextLink

Check the API JSON response for an @odata.nextLink property. If present, make a new GET request to that exact URL to fetch the next page of results. Repeat this process until @odata.nextLink is no longer returned.

Use the calendarView Endpoint with Pagination Handling

Correct Setup: When formatted correctly, your initial request should look like: GET https://graph.microsoft.com/v1.0/me/calendarView?startDateTime=2025-01-01T00:00:00Z&endDateTime=2025-12-31T23:59:59Z&$top=1000.

Solution 2

Verify Calendar Permissions and Configuration

If events are still missing despite correct pagination, check user permissions and calendar targeting settings.

Frequently Asked Questions

Why is Microsoft Graph API only returning a few calendar events?

By default, Microsoft Graph paginates results and may return a limited number of items (often 10). You must use the $top query parameter to increase the page size and follow the @odata.nextLink URL in the response to retrieve remaining events.

What is the difference between the events and calendarView endpoints?

The events endpoint returns the master series of recurring meetings but does not expand them into individual occurrences. The calendarView endpoint requires a start and end date and automatically expands recurring series into single instances.

How do I correctly format the date for the calendarView endpoint?

You must use the ISO 8601 format, including the time zone indicator. For example, 2025-01-01T00:00:00Z represents midnight on January 1, 2025, in Coordinated Universal Time (UTC).
