Namespace: microsoft.graph

Important

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

Caution

The Outlook tasks API is deprecated and stopped returning data on August 20, 2022. Use the To Do API instead.

An Outlook item that can track a work item.

You can use a task to track:

  • The start, due, and actual completion dates and times.
  • The progress or status of the task.
  • The recurrence and reminder statuses of the task.

Date-related properties in the outlookTask resource include the following:

  • completedDateTime
  • createdDateTime
  • dueDateTime
  • lastModifiedDateTime
  • reminderDateTime
  • startDateTime

By default, the POST, GET, PATCH, and complete operations return date-related properties in their REST responses in UTC. You can use the Prefer: outlook.timezone header to have all the date-related properties in the response represented in a time zone different than UTC. The following example returns date-related properties in EST in the corresponding response:

Prefer: outlook.timezone="Eastern Standard Time"
