[DEPRECATED] Outlook Mail REST API reference (beta)

  • Articolo

Applies to: Exchange Online | Office 365 | Hotmail.com | Live.com | MSN.com | Outlook.com | Passport.com

Note

The beta version of the Outlook REST API is deprecated.

As announced on November 17, 2020, version 2.0 of the Outlook REST API has been deprecated. Consequently, the beta REST endpoint is also deprecated and will be fully decommissioned in November 2022. Migrate existing apps to use Microsoft Graph. See a comparison to start your migration.

Not interested in the beta version of the API? In the table of contents on the left, go to the Office 365 REST API reference section and select the version you want.

All Mail API operations

Message operations

Messages are stored in mailbox folders, so message endpoints often include the folder that contains the message. A folder is either specified by ID or by one of the following well-known folder names: Inbox, Drafts, SentItems, or DeletedItems.

Folder operations

Mailbox folders can contain messages and other folders. You can get, create, change, delete, and manage folders. You can use the following well-known folder names instead of the ID to specify the corresponding folder: Inbox, SentItems, Drafts, or DeletedItems.

Authentication

Like other Outlook REST API, for every request to the Mail API, you should include a valid access token. Getting an access token requires you to have registered and identified your app, and obtained the appropriate authorization.

You can find out more about some streamlined registration and authorization options for you. Keep this in mind as you proceed with the specific operations in the Mail API.

Version of API

The Mail REST API is supported in all versions of the Outlook REST API. The functionality may differ depending on the specific version.

Target user

All Mail API requests are performed on behalf of the signed-in user unless specified. A few API subsets, such as Focused Inbox API, can be performed on the signed-in user, or a user specified by a user ID, given the appropriate permissions.

See Use the Outlook REST API for more information common to all subsets of the Outlook REST API.

Get messages

You can get a message collection or an individual message from a mailbox folder.

Each message in the response contains multiple properties, including the Body property. The message body can be either text or HTML. If the body is HTML, by default, any potentially unsafe HTML (for example, JavaScript) embedded in the Body property would be removed before the body content is returned in a REST response.

To get the entire, original HTML content, include the following HTTP request header:

Prefer: outlook.allow-unsafe-html

To specify the desired format to be returned in the Body and UniqueBody properties in a GET request, use the Prefer: outlook.body-content-type header:

  • Specify Prefer: outlook.body-content-type="text" to get a message body returned in text format.
  • Specify Prefer: outlook.body-content-type="html", or just skip the header, to return the message body in HTML format.

If you specify either header, the response will include the corresponding Preference-Applied header as confirmation:

  • For text format requests: Preference-Applied: outlook.body-content-type="text"
  • For HTML format requests: Preference-Applied: outlook.body-content-type="html"

Get a message collection

Minimum required scope

One of the following:

Note

The behavior of the operations in this section vary by version. Find out more by choosing a version under Office 365 REST API reference in the table of contents on the left.

Get a message collection from the entire mailbox of the signed-in user (including the Deleted Items and Clutter folders).

GET https://outlook.office.com/api/beta/me/messages

You can also specify a folder in the user's mailbox and get the message collection from that folder.

GET https://outlook.office.com/api/beta/me/MailFolders/{folder_id}/messages
Required parameter Type Description
URL parameters
folder_id string The folder ID, or the Inbox, Drafts, SentItems, or DeletedItems well-known folder name, if you're getting messages from a specific folder. Specifying AllItems would return all messages from the entire mailbox

Note

By default, each message in the response includes all its properties. Use $select to specify only those properties you need for best performance. The Id property is always returned. See OData query parameters for filtering, sorting, and paging parameters.

The following example shows how to use $select to specify returning only the Sender and Subject properties of each message in the response. Refer to the sample response in Get a message for a full list of properties that would be returned for a message if you don't use $select.

Response type

The requested message.

Note

By default, the response includes all the properties of the specified message. Use $select to specify only those properties you need for best performance. The Id property is always returned. See OData query parameters for filtering, sorting, and paging parameters.

The following example shows how to use $select to specify returning only the Sender and Subject properties of the message in the response.

GET https://outlook.office.com/api/beta/me/messages/AAMkAGE1I5MTAAA=?$select=Sender,Subject

Synchronize messages

Minimum required scope

One of the following:

You can synchronize your local data store with the messages on the server. Message synchronization is a per-folder operation, for example, you can synchronize all of the messages in your Inbox. To synchronize the messages in a folder hierarchy you need to synchronize each folder individually.

The API supports both full synchronization that retrieves all of the messages in a folder, and incremental synchronization that retrieves all of the messages that have changed since the last full synchronization.

Synchronizing a mail folder typically requires two or more GET requests. You make the GET request much like the way you get messages, except that you include certain request headers, and a deltaToken or skipToken when appropriate.

Request headers

  • You must specify the Prefer: odata.track-changes header in all sync requests, except those that include a skipToken that is returned from a previous sync request. In the first response, look for the Preference-Applied: odata.track-changes header to confirm that the resource supports synchronizing before proceeding.

  • You may specify the Prefer: odata.maxpagesize={x} header to set the maximum number of messages returned in a request.

This is a full message synchronization round:

  1. Make the initial GET request with the mandatory Prefer: odata.track-changes header. The initial response to a sync request always returns a deltaToken. (The second and subsequent GET requests differ from the first GET request by including either a deltaToken or a skipToken received in a previous response.)

  2. If the first response returns the Preference-Applied: odata.track-changes header, you can proceed with synchronizing the folder.

  3. Make a second GET request. Specify the Prefer: odata.track-changes header and the deltaToken returned from the first GET to determine if there are any additional messages. The second request will return additional messages, and either a skipToken if there are more messages available, or a deltaToken if the last message has been synchronized, in which case the synchronization round is complete and you can stop.

  4. Continue synchronizing by sending a GET call and including a skipToken that's returned from the previous call. Stop when you get a final response that contains an @odata.deltaLink header with a deltaToken again, which indicates the sync is complete.

Cache the last delta token received in the full synchronization round. Use it to start an incremental synchronization round.

This is an incremental synchronization round:

  1. Make the initial GET request with the mandatory Prefer: odata.track-changes header and the cached deltaToken received in the last response of a full synchronization round.

  2. The second and subsequent steps follow the pattern used for a full synchronization.

To sync messages in a specific folder

Initial request

GET https://outlook.office365.com/api/beta/me/MailFolders('{folder_id}')/messages

Second request, or first request of a subsequent round

GET https://outlook.office365.com/api/beta/me/MailFolders('{folder_id}')/messages/?$deltaToken={delta_token}

Third or subsequent request in the same round

Continue to send the next sync request if the previous response includes a skipToken. Stop when you get a response that contains an @odata.deltaLink header with a deltaToken again.

GET https://outlook.office365.com/api/beta/me/MailFolders('{folder_id}')/messages/?$skipToken={skip_token}
Parameters Type Description
Header parameters
Prefer odata.track-changes Indicates that the request is a synchronization request. Required for the first 2 GET requests in a round.
Prefer odata.maxpagesize Sets the number of messages to be returned in each response. Optional.
URL parameters
folder_id string The folder ID, or the Inbox, Drafts, SentItems, or DeletedItems well-known folder name to synchronize. Required.
deltaToken String The token that identifies the last sync request for that folder. It is returned as part of the value for @odata.deltaLink in that previous sync response. Required for the second GET request.
skipToken String The token that indicates that there are more messages to download. Required if it is returned as part of the value for @odata.nextLink in the previous sync response.

By default synchronization returns all of the properties and all of the messages in a folder. Use a $select query expression to specify only the properties that your need for best performance. The Id property is always returned.

Synchronization supports the query expressions $select, $top, $expand. There is limited support for $filter and $orderby, and no support for $search.

  • The only supported $filter expresssions are “$filter=ReceivedDateTime+ge+{value}” or “$filter=ReceivedDateTime+gt+{value}".
  • The only supported $orderby expression is “$orderby=ReceivedDateTime+desc”. If you do not include an $orderby expression, the return order is not guaranteed.

See OData query parameters for filtering, sorting, and paging parameters.

Response type

A collection containing the requested messages, and a deltaToken or skipToken that you use to request additional pages of message data from server for an incremental synchronization.

Example

The following example shows a series of requests to synchronize a specific folder which contains 7 messages. The first sync request specifies returning 2 messages at a time (odata.maxpagesize is 2), and only the Sender and Subject properties for each message.

  • The initial response returns 2 messages, a deltaLink and deltaToken.
  • The second request uses that deltaToken. The second response returns 2 messages, a nextLink and skipToken.
  • To complete the sync, the third and fourth requests use the skipToken returned from the previous sync request, until the fourth sync response returns a deltaLink and deltaToken, in which case this round of sync is complete. Save the deltaToken for the next round of sync.

Sample initial request

GET https://outlook.office.com/api/beta/Me/MailFolders('AAMkAGI5MAAAwW-j-AAA=')/messages?$select=Subject,Sender HTTP/1.1
Prefer: odata.maxpagesize=2
Prefer: odata.track-changes

Sample initial response data

The initial response includes a Preference-Applied: odata.track-changes header, indicating that this folder supports synchronization. The response also includes two messages and a deltaToken.

Preference-Applied: odata.track-changes

Response type

The new copy of the message.

Manage Focused Inbox

Focused Inbox allows you to view important messages in the Focused tab of the Inbox, and the rest of the Inbox messages in the Other tab. The classification system initially organizes Inbox messages in a default way. You can correct and train the system over time through the user interface or programmatically. The more you use it, the better the system can infer which incoming message as important.

At the programmatic level, the Focused Inbox REST API works on the specified user's messages, and supports an InferenceClassification property for each message. The possible values are Focused and Other, which indicate whether the user considers that message as, respectively, more important and less important. To correct and train the message classification system, use the PATCH operation on the InferenceClassification property at the message level.

The Focused Inbox REST API also lets you create overrides. Each override, represented by an InferenceClassificationOverride instance, is an instruction for the classification system to always designate messages from a specific sender in a consistent way (i.e., always as "Focused" or always as "Other"), regardless of any previously learned approach. You can create, get, update and delete overrides for the specified user. That user's overrides, if any, are accessible in an InferenceClassification navigation property, which is a collection of InferenceClassificationOverride instances. Overrides allow a user more control over the classification of incoming messages, and build greater trust of the classification system.

Note that the classification system learns and applies classification only on incoming messages in the Inbox. Messages in other folders are by default "Focused". Setting up an override affects future messages arriving in the Inbox; the override doesn't modify the InferenceClassification property in existing messages in any folder including the Inbox.

Training the message classification system

Using overrides to classify consistently per sender

Update message classification

Minimum required scope

One of the following:

Change the InferenceClassification property of the specified message. If the message is in the Inbox, the user will see that message under the corresponding Focused or Other tab. This kind of correction also trains the message classification system to customize future classification for the specified user.

PATCH https://outlook.office.com/api/beta/me/messages('{message_id}')

PATCH https://outlook.office.com/api/beta/Users('{user_id}')/messages('{message_id}')
Parameter Type Description
URL parameters
message_id string The ID of the draft message to send.
user_id string The user's email address.

Response type

The updated message.

Sample request

This example changes the InferenceClassification property to Other for the specified message of the signed-in user's.

PATCH https://outlook.office.com/api/beta/me/messages('AAMkADA1MTQBAAA=')

{
    "InferenceClassification": "Other"
}

Sample response

The response object shown here shows the updated InferenceClassification property and is truncated for brevity. An actual PATCH request returns all the properties of the message.

Create an override for a sender

Minimum required scope

One of the following:

Create an override for a sender identified by an SMTP address. Future messages from that SMTP address will be consistently classified as specified in the override.

Note

  • If an override already exists with the same STMP address, then the ClassifyAs and Name fields of that override are updated with the provided values.
  • The maximum number of overrides supported for a mailbox is 1000, based on unique sender SMTP addresses.
  • The POST operation supports creating only one override at a time. To create multiple overrides, you can send multiple POST requests or batch them.
POST https://outlook.office.com/api/beta/me/InferenceClassification/Overrides

POST https://outlook.office.com/api/beta/Users('{user_id}')/InferenceClassification/Overrides
Parameter Type Description
URL parameters
user_id string The user's email address.

Manage @-Mentions (preview)

Calling out a recipient to get the recipient's attention in a message is a common social gesture. The Mention resource provides a light-weight mechanism to notify another recipient, or to get a notification from a sender in a message.

Through the user interface, an app can let a user insert a mention in a message by preceding the mention with @ (commonly used for similar scenarios in other apps, hence the term @-mention). Programmatically, the app can create the mention by adding it to the Mentions property in the same POST call to create the message.

The app can let users look up whether they have been notified in any messages in their Inbox. Users can find details of each mention in a message. They can also delete a mention in a message.

Create mentions in a new message

Get information about mentions in a message

Delete a mention in a message

Create and send mentions as part of a new message

Get all messages that mention the signed-in user

Minimum required scope

One of the following:

Get all the messages in the signed-in user's mailbox, or in the specified folder, that contain a Mention of this user.

This uses the same GET method available on the Message resource; in addition, you include a $filter query parameter on the MentionsPreview property.

By default, a GET /me/messages call does not return the Mentions property. Use the $expand query parameter to find details of each mention in a message.

Note

Make sure your actual call encodes the space characters in the query parameter string appropriately.

GET https://outlook.office.com/api/beta/me/messages?$filter=MentionsPreview/IsMentioned eq true

GET https://outlook.office.com/api/beta/me/MailFolders/{folder_id}/messages?$filter=MentionsPreview/IsMentioned eq true
Required parameter Type Description
URL parameters
folder_id string The destination folder ID, or the Inbox or Drafts well-known folder name.

Response type

The requested message collection.

Sample request

The example below filters all messages in the signed-in user's mailbox for those that mention the user. It uses $select to return a subset of the properties of each message in the response. It also incorporates URL encoding for the space characters in the query parameter string.

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

Sample response

The response contains two messages that mention the signed-in user.

Unsubscribe (preview)

Minimum required scope

One of the following:

Submits a email request on behalf of the signed-in user to unsubscribe from an email distribution list. Uses the information in the List-Unsubscribe header.

POST https://outlook.office.com/api/beta/me/messages('{message_id}')/unsubscribe
Required parameter Type Description
URL parameters
message_id string The ID of the draft message to send.

Message senders can use mailing lists in a user-friendly way by including the option for recipients to opt out. They can do so by specifying the List-Unsubscribe header in each message following RFC-2369.

Note

In particular, for the Unsubscribe action to work, the sender must specify mailto: and not URL-based unsubscribe information.

Setting that header would also set the UnsubscribeEnabled property of the Message instance to true, and the UnsubscribeData property to the header data.

If the UnsubscribeEnabled property of a message is true, you can use the Unsubscribe action to unsubscribe the user from similar future messages as managed by the message sender.

A successful Unsubscribe action moves the message to the Deleted Items folder. The actual exclusion of the user from future mail distribution is managed by the sender.

Sample request

POST https://outlook.office.com/api/beta/me/messages('AAMkADA1MTk1ZAAAKXBQCAAA=')/unsubscribe

Sample response

Status code: 202 Accepted
