Hi,

I need to download attachments from selected Office365 email recursively.

I tried below request from one of the solution provided online,

RequestUri = {https://graph.microsoft.com/v1.0/me/mailFolders/Inbox/messages/{msgID}/attachments/{attachedmsgID}=/?$expand = microsoft.graph.itemattachment/item}

but getting below response.

StatusCode: 404, ReasonPhrase: 'Not Found'

can anyone please let me know how do I fetch itemAttachments and its attachments?

Answer 1

Hi @Supriya A ,

For getting the itemAttachements of mail please follow the below instructions:

Expand and get the properties of the item attached to a message:

GET https://graph.microsoft.com/v1.0/me/messages/AAMkADA1M-zAAA=/attachments/AAMkADA1M-CJKtzmnlcqVgqI=/?$expand=microsoft.graph.itemattachment/item  

Expand and get the properties of an item attached to a message, including any attachment to the item:

GET https://graph.microsoft.com/v1.0/me/messages/AAMkADA1M-zAAA=/attachments/AAMkADA1M-CJKtzmnlcqVgqI=/?$expand=microsoft.graph.itemattachment/item  

For fetching these details you need to have the following permission:

You can also decode your Token in the https://jwt.ms/ and check in scope whether these permissions are already available.

Answer 2

Hi @Supriya A ,

Hope you are doing well.

As per documentation,attachment-get and query-parameters we can get attachment of mail message and can use query parameters to customize responses.

$expand query parameter can be used as shown below. I have tried this in graph explorer and I could able to get correct response as shown below.

GET https://graph.microsoft.com/v1.0/me/mailFolders/Inbox/messages/{messageID}/attachments/{attachmentID}$expand=microsoft.graph.itemattachment/item

So we are unable to reproduce this issue.

You are getting StatusCode: 404, ReasonPhrase: 'Not Found' so Please try to use graph api endpoint attachment-get and check weather this attachment file is still available for particular mail message or not.

Hope this helps.

Hi, I was not able to comment so writing an answer,
@AtulThorat-MSFT , I tried with below endpoint,

RequestUri = {https://graph.microsoft.com/v1.0/me/mailFolders/Inbox/messages/{msg-id}/attachments/{attachment-id}/?$Value}

and getting below response,

{
"@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users('supriyatest2021%40outlook.com')/mailFolders('Inbox')/messages('AQMkADAwATM3ZmYAZS00NjJhLWFiYgA2LTAwAi0wMAoARgAAA4Amv2sM8nJEo5QlvuMbUbMHAOyxeWKJD4JHrqegw15KyEAAAAIBDAAAAOyxeWKJD4JHrqegw15KyEAAAACEBqjhAAAA')/attachments/$entity",
"@odata.type": "#microsoft.graph.itemAttachment",
"id": "AQMkADAwATM3ZmYAZS00NjJhLWFiYgA2LTAwAi0wMAoARgAAA4Amv2sM8nJEo5QlvuMbUbMHAOyxeWKJD4JHrqegw15KyEAAAAIBDAAAAOyxeWKJD4JHrqegw15KyEAAAACEBqjhAAAAARIAEACURMvi8EaiSpv2FuT4p1iS",
"lastModifiedDateTime": "2022-06-15T05:16:48Z",
"name": "test 1",
"contentType": "message/rfc822",
"size": 8575119,
"isInline": false
}

means the itemAttachment is present, then not sure why I am not able to get the item itself, when I try below?

{https://graph.microsoft.com/v1.0/me/mailFolders/Inbox/messages/{msgID}/attachments/{attachedmsgID}=/?$expand = microsoft.graph.itemattachment/item}

Also this itemAttachment has another fileAttachment, but I do not get ContentID in above response( with $Value)?
