[DEPRECATED] Outlook Mail REST API reference (version 1.0)

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

Note

Version 1.0 of the Outlook REST API is deprecated.

As announced in October 2017, version 1.0 of the Outlook REST API has been deprecated. The v1.0 REST endpoint will be fully decommissioned, and the v1.0 documentation will be removed shortly afterwards. Migrate existing apps to use Microsoft Graph. See a comparison to start your migration.

The Outlook Mail API lets you read, create, and send messages and attachments, view and respond to event messages, and manage folders that are secured by Azure Active Directory in Office 365. It also provides the same functionality in Microsoft accounts, specifically in these domains: Hotmail.com, Live.com, MSN.com, Outlook.com, and Passport.com.

Note

For simplicity of reference, the rest of this article uses Outlook.com to include these Microsoft account domains.

Not interested in v1.0 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

Currently, the GET operation returns message bodies in only HTML format.

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 Inbox.

GET https://outlook.office.com/api/v1.0/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/v1.0/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.

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.

Sample request

GET https://outlook.office.com/api/v1.0/me/folders/sentitems/messages/?$select=Sender,Subject
