List messages

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.

Get the messages in the signed-in user's mailbox (including the Deleted Items and Clutter folders).

Depending on the page size and mailbox data, getting messages from a mailbox can incur multiple requests. The default page size is 10 messages. Use $top to customize the page size, within the range of 1 and 1000.

To improve the operation response time, use $select to specify the exact properties you need; see example 1 below. Fine-tune the values for $select and $top, especially when you must use a larger page size, as returning a page with hundreds of messages each with a full response payload may trigger the gateway timeout (HTTP 504).

To get the next page of messages, simply apply the entire URL returned in @odata.nextLink to the next get-messages request. This URL includes any query parameters you may have specified in the initial request.

Do not try to extract the $skip value from the @odata.nextLink URL to manipulate responses. This API uses the $skip value to keep count of all the items it has gone through in the user's mailbox to return a page of message-type items. It's therefore possible that even in the initial response, the $skip value is larger than the page size. For more information, see Paging Microsoft Graph data in your app.

You can filter on the messages and get only those that include a mention of the signed-in user. See an example below. By default, the GET /me/messages operation does not return the mentions property. Use the $expand query parameter to find details of each mention in a message.

There are two scenarios where an app can get messages in another user's mail folder:

  • If the app has application permissions, or,
  • If the app has the appropriate delegated permissions from one user, and another user has shared a mail folder with that user, or, has given delegated access to that user. See details and an example.

This API is available in the following national cloud deployments.

Global service US Government L4 US Government L5 (DOD) China operated by 21Vianet

Permissions

Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

Permission type Least privileged permissions Higher privileged permissions
Delegated (work or school account) Mail.ReadBasic Mail.ReadWrite, Mail.Read
Delegated (personal Microsoft account) Mail.ReadBasic Mail.ReadWrite, Mail.Read
Application Mail.ReadBasic.All Mail.ReadWrite, Mail.Read

HTTP request

To get all the messages in a user's mailbox:

GET /me/messages
GET /users/{id | userPrincipalName}/messages

To get messages in a specific folder in the user's mailbox:

GET /me/mailFolders/{id}/messages
GET /users/{id | userPrincipalName}/mailFolders/{id}/messages

To get all the messages in the user's mailbox that include a mention of the user:

GET /me/messages?$filter=mentionsPreview/isMentioned eq true
GET /users/{id | userPrincipalName}/messages?$filter=mentionsPreview/isMentioned eq true

Optional query parameters

This method supports the OData Query Parameters to help customize the response.

You can use the $filter query parameter on the mentionsPreview property to get those messages that mention the signed-in user.

Using filter and orderby in the same query

When using $filter and $orderby in the same query to get messages, make sure to specify properties in the following ways:

  1. Properties that appear in $orderby must also appear in $filter.
  2. Properties that appear in $orderby are in the same order as in $filter.
  3. Properties that are present in $orderby appear in $filter before any properties that aren't.

Failing to do this results in the following error:

  • Error code: InefficientFilter
  • Error message: The restriction or sort order is too complex for this operation.

Request headers

Name Type Description
Authorization string Bearer {token}. Required.
Prefer: outlook.body-content-type string The format of the body and uniqueBody properties to be returned in. Values can be "text" or "html". If the header is not specified, the body and uniqueBody properties are returned in HTML format. Optional.

Request body

Don't supply a request body for this method.

Response

If successful, this method returns a 200 OK response code and collection of message objects in the response body.

Examples

Example 1: List all messages

Request

The first example gets the default, top 10 messages in the signed-in user's mailbox. It uses $select to return a subset of the properties of each message in the response.

GET https://graph.microsoft.com/beta/me/messages?$select=sender,subject

Response

The following example shows the response. To get the next page of messages, apply the URL returned in @odata.nextLink to a subsequent GET request.

HTTP/1.1 200 OK
Content-type: application/json

{
  "@odata.context": "https://graph.microsoft.com/beta/$metadata#users('bb8775a4-4d8c-42cf-a1d4-4d58c2bb668f')/messages(sender,subject)",
  "value": [
    {
      "@odata.etag": "W/\"CQAAABYAAADHcgC8Hl9tRZ/hc1wEUs1TAAAwR4Hg\"",
      "id": "AAMkAGUAAAwTW09AAA=",
      "subject": "You have late tasks!",
      "sender": {
        "emailAddress": {
          "name": "Microsoft Planner",
          "address": "noreply@Planner.Office365.com"
        }
      }
    }
  ]
}

Example 2: Use $filter to get all messages satisfying a specific condition

Request

The next example filters all messages in the signed-in user's mailbox for those that mention the user. It also uses $select to return a subset of the properties of each message in the response.

The following example also incorporates URL encoding for the space characters in the query parameter string.

GET https://graph.microsoft.com/beta/me/messages?$filter=MentionsPreview/IsMentioned%20eq%20true&$select=Subject,Sender,ReceivedDateTime,MentionsPreview

Response

The following example shows the response.

Note: The response object shown here might be shortened for readability.

HTTP/1.1 200 OK
Content-type: application/json

{
  "@odata.context":"https://graph.microsoft.com/beta/$metadata#me/messages(subject,sender,receivedDateTime,mentionsPreview)",
  "value":[
    {
      "@odata.id":"https://graph.microsoft.com/beta/users('266efe5a-0fd7-4edd-877b-b2d1e561f193@ae01a323-3934-4475-a32d-af1274312bb0')/messages('AQMkADJmMTUAAAgVZAAAA')",
      "@odata.etag":"W/\"CQAAABYAAAAPFhK2FclcRbABBJhCde8iAAAAAATI\"",
      "id":"AQMkADJmMTUAAAgVZAAAA",
      "receivedDateTime":"2016-07-21T07:40:21Z",
      "subject":"Re: Start planning soon",
      "sender":{
        "emailAddress":{
          "name":"Adele Vance",
          "address":"AdeleV@contoso.com"
        }
      },
      "mentionsPreview":{
        "isMentioned":true
      }
    }
  ]
}

Example 3: Use prefer header to get the message body and uniqueBody is text format

Request

The third example shows how to use a Prefer: outlook.body-content-type="text" header to get the body and uniqueBody properties of each message in text format.

GET https://graph.microsoft.com/beta/me/messages?$select=subject,body,bodyPreview,uniqueBody
Prefer: outlook.body-content-type="text"

Response

The following example shows the response.

HTTP/1.1 200 OK
Content-type: application/json

{
  "@odata.context":"https://graph.microsoft.com/beta/$metadata#users('cd209b0b-3f83-4c35-82d2-d88a61820480')/messages(subject,body,bodyPreview,uniqueBody)",
  "value":[
    {
      "@odata.type":"#microsoft.graph.eventMessageRequest",
      "@odata.etag":"W/\"CwAAABYAAABmWdbhEgBXTophjCWt81m9AAAoZYj5\"",
      "id":"AAMkAGIAAAoZCfIAAA=",
      "subject":"Orientation ",
      "bodyPreview":"Dana, this is the time you selected for our orientation. Please bring the notes I sent you.",
      "body":{
        "contentType":"text",
        "content":"Dana, this is the time you selected for our orientation. Please bring the notes I sent you.\r\n"
      },
      "uniqueBody":{
        "contentType":"text",
        "content":"Dana, this is the time you selected for our orientation. Please bring the notes I sent you.\r\n"
      }
    }
  ]
}
