How to get In-Place archive mailbox in Exchange Online using Office 365 APIs

I want to get list of folders/emails inside In-Place mailboxes. But both mailbox list and folder list doesn't returns In-Place mailboxes.

This is what I have tried till now:

  1. Get mailboxes using following request

Request:

https://outlook.office365.com/api/v1.0/users('[email protected]')

Response:

{
    "@odata.context": "https://outlook.office365.com/api/v2.0/$metadata#Users/$entity",
    "@odata.id": "https://outlook.office365.com/api/v2.0/Users('12637010-f344-4827-9e3b-21218392985d@649b37da-e479-45dc-a099-fda797d7fcee')",
    "Id": "12637010-f344-4827-9e3b-21218392985d@649b37da-e479-45dc-a099-fda797d7fcee",
    "EmailAddress": "[email protected]",
    "DisplayName": "User Name",
    "Alias": "user1",
    "MailboxGuid": "12312312-a498-46d1-93a8-870cd3faffec"
}
  1. Get folders listing

Request:

https://outlook.office365.com/api/v1.0/users('[email protected]')/folders?$top=100

Response:

{
    "@odata.context": "https://outlook.office365.com/api/v1.0/$metadata#Users('someuser%40somedomain.onmicrosoft.com')/Folders",
    "value": [{
        "@odata.id": "https://outlook.office365.com/api/v1.0/Users('[email protected]')/Folders('ABCDA3AYxNjE2NjQyLWE0OTgtNDZkMy05M2E4LTg3MGNkM2ZhZmZlYwAuAAAAAACbFtMO1RLxQoChh4quwNSoAQChU257vJJfSLjbblRIqUFSAABgaA9RAAA=')",
        "Id": 'ABCDA3AYxNjE2NjQyLWE0OTgtNDZkMy05M2E4LTg3MGNkM2ZhZmZlYwAuAAAAAACbFtMO1RLxQoChh4quwNSoAQChU257vJJfSLjbblRIqUFSAABgaA9RAAA=',
        "DisplayName": "Clutter",
        "ParentFolderId": "ABCDAAVCNjE2NjQyLWE0OTgtNDZkMy05M2E4LTg3MGNkM2ZhZmZlYwAuAAAAAACbFtMO1RLxQoChh4quwNSoAQChU257vJJfSLjbblRIqUFSAAAAAAEIAAA=",
        "ChildFolderCount": 0,
        "UnreadItemCount": 0,
        "TotalItemCount": 1
    },
    {
.... other folders like Inbox, Conversations, Conversations history etc.
    }]
}

Is it possible to get it use Office 365 unified APIs? If not, is there any alternative? If yes, how does In-Place mailboxes are treated by Exchange online; folder-level(doesn't looks like) or at user level mailboxes?

Note: I have changed sensitive information in requests and responses

Solution

  • Is it possible to get it use Office 365 unified APIs? If not, is there any alternative?

    Archive mailboxes (called an In-Place Archive in Exchange Online) are secondary mailboxes that are associated with a user. The Office 365 API does not support accessing to archive mailboxes.

    BTW, achieving is a feature of Exchange, the EWS API supports archiving an item, but it does not support listing mails in achieve mailbox either (Archiving in EWS in Exchange).

    For new feature request of Office 365 API, you can consider submitting it on Office Developer Platform UserVoice.
