Create outlookTask

Important

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported.

Create an Outlook task in the default task group (My Tasks) and default task folder (Tasks) in the user's mailbox.

The POST method always ignores the time portion of startDateTime and dueDateTime in the request body, and assumes the time to be always midnight in the specified time zone.

By default, this operation (and the GET, PATCH, and complete task operations) returns date-related properties 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.

Permissions

One of the following permissions is required to call this API. To learn more, including how to choose permissions, see Permissions.

Permission type Permissions (from least to most privileged)
Delegated (work or school account) Tasks.ReadWrite
Delegated (personal Microsoft account) Tasks.ReadWrite
Application Not supported.

HTTP request

POST /me/outlook/tasks
POST /users/{id|userPrincipalName}/outlook/tasks

Request headers

Name Description
Authorization Bearer {token}. Required.
Prefer: outlook.timezone Specifies the time zone for time properties in the response, which would be in UTC if this header is not specified. Optional.

Request body

In the request body, supply a JSON representation of outlookTask object.

Response

If successful, this method returns 201 Created response code and outlookTask object in the response body.

Example

Request

The following example shows the use of the Prefer: outlook.timezone header. It creates a task, expresses startDateTime and dueDateTime in Eastern Standard Time (EST), and includes a Prefer header of Pacific Standard Time (PST).

POST https://graph.microsoft.com/beta/me/outlook/tasks
Prefer: outlook.timezone="Pacific Standard Time"
Content-type: application/json
Content-length: 276

{
  "assignedTo": "Dana Swope",
  "subject": "Shop for children's weekend",
  "startDateTime": {
      "dateTime": "2016-05-03T09:00:00",
      "timeZone": "Eastern Standard Time"
  },
  "dueDateTime":  {
      "dateTime": "2016-05-05T16:00:00",
      "timeZone": "Eastern Standard Time"
  }
}

In the request body, supply a JSON representation of outlookTask object.

Response

The POST method ignores the time portion of startDateTime and dueDateTime in the request body and assumes the time to be always midnight in the specified time zone (EST).

Since the Prefer header specifies PST, the POST method expresses all the date-related properties in the response in PST. In particular, for the startDateTime and dueDateTime properties, the POST method converts midnight in EST to PST and returns them in PST in the response.

Note: The response object shown here may be truncated for brevity. All of the properties will be returned from an actual call.

SDK sample code


GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var outlookTask = new OutlookTask
{
	AssignedTo = "Dana Swope",
	Subject = "Shop for children's weekend",
	StartDateTime = new DateTimeTimeZone
	{
		DateTime = "2016-05-03T09:00:00",
		TimeZone = "Eastern Standard Time"
	},
	DueDateTime = new DateTimeTimeZone
	{
		DateTime = "2016-05-05T16:00:00",
		TimeZone = "Eastern Standard Time"
	}
};

await graphClient.Me.Outlook.Tasks
	.Request()
	.Header("Prefer","outlook.timezone=\"Pacific Standard Time\"")
	.AddAsync(outlookTask);
