Use the Microsoft Search API to search Outlook calendar events

  • Article

Use the Microsoft Search API in Microsoft Graph to search for events in the signed-in user’s primary calendar. The user identity for the search is based on the auth token.

Caution

The search API schema has changed in the beta version. Some properties in a search request and response have been renamed or removed. For details, see Schema change deprecation warning. The examples in this topic show the up-to-date schema.

Example

Request

This example searches in the user's calendar for the keyword "contoso", and returns up to 25 results.

Known limitations

  • You can access only the signed-in user’s own mailbox. Searching delegated mailboxes is not supported.
  • For events, the total property of the searchHitsContainer type contains the number of results on the page, not the total number of matching results.
  • Sorting results is not supported for events. A sort clause in the request returns a Bad Request error code in the response.
