HTTP request

You can create extended properties in a new or existing resource instance.

To create one or more extended properties in a new resource instance, use the same REST request as creating the instance, and include the properties of the new resource instance and extended property in the request body. Some resources support creation in more than one way. For more information on creating these resource instances, see the corresponding topics for creating a message, mailFolder, event, calendar, contact, contactFolder, Outlook task, Outlook task folder, group event, and group post.

The following is the syntax of the requests.

Request headers

Name	Value
Authorization	Bearer {token}. Required. Learn more about authentication and authorization.
Content-Type	application/json

Request body

Provide a JSON body of each singleValueLegacyExtendedProperty object in the singleValueExtendedProperties collection property of the resource instance.

Property	Type	Description
singleValueExtendedProperties	singleValueLegacyExtendedProperty collection	An array of one or more single-valued extended properties.
id	String	For each property in the singleValueExtendedProperties collection, specify this to identify the property. It must follow one of the supported formats. See Outlook extended properties overview for more information. Required.
value	string	For each property in the singleValueExtendedProperties collection, specify the property value. Required.

When creating an extended property in a new resource instance, in addition to the new singleValueExtendedProperties collection, provide a JSON representation of that resource instance (that is, a message, mailFolder, event, etc.)

Response

Response code

An operation successful in creating an extended property in a new resource instance returns 201 Created, except in a new group post, depending on the method used, the operation can return 200 OK or 202 Accepted.

In an existing resource instance, a successful create operation returns 200 OK.

Response body

When creating an extended property, the response includes only the new or existing instance but not the new extended property. To see the newly created extended property, get the instance expanded with the extended property.

When creating an extended property in a new group post by replying to a thread or post, the response includes only a response code but not the new post nor the extended property.

Example

Request 1

The first example creates a new event and a single-value extended property in the same POST operation. Apart from the properties you'd normally include for a new event, the request body includes the singleValueExtendedProperties collection that contains one single-value extended property, and the following for the property:

id specifies the property type as String, the GUID, and the property named Fun.
value specifies Food as the value of the Fun property.

POST https://graph.microsoft.com/beta/me/events
Content-Type: application/json

{
  "subject": "Celebrate Thanksgiving",
  "body": {
    "contentType": "HTML",
    "content": "Let's get together!"
  },
  "start": {
      "dateTime": "2015-11-26T18:00:00",
      "timeZone": "Pacific Standard Time"
  },
  "end": {
      "dateTime": "2015-11-26T23:00:00",
      "timeZone": "Pacific Standard Time"
  },
  "attendees": [
    {
      "emailAddress": {
        "address": "Terrie@contoso.com",
        "name": "Terrie Barrera"
      },
      "type": "Required"
    }
  ],
  "singleValueExtendedProperties": [
     {
           "id":"String {66f5a359-4659-4830-9070-00040ec6ac6e} Name Fun",
           "value":"Food"
     }
  ]
}

Response 1

A successful response is indicated by an HTTP 201 Created response code, and includes the new event in the response body, similar to the response from creating just an event. The response doesn't include any newly created extended properties.

To see the newly created extended property, get the event expanded with the extended property.

Request 2

The second example creates one single-value extended property for the specified existing message. That extended property is the only element in the singleValueExtendedProperties array. The request body includes the following for the extended property:

id specifies the property type as String, the GUID, and the property named Color.
value specifies Green as the value of the Color property.

         "value":"Green"
      }
    ]
}

Response 2

A successful response is indicated by an HTTP 200 OK response code, and includes the specified message in the response body, similar to the response from updating a message. The response doesn't include the newly created extended property.

To see the newly created extended property, get the message expanded with the extended property.
