Microsoft Graph Api Download Attachment C

[Margart Sarafin]

I'm trying to send email with inline attachment using MS Graph. I know how to send email without attachment but when I'm trying to send message with attachment I don't know how can I add this attachment to the message.Here is my code:

Depending on the resource (event, message, or post) that the attachment is attached to and the permission type (delegated or application) requested, the permission specified in the following table is the least privileged required to call this API. To learn more, including taking caution before choosing more privileged permissions, search for the following permissions in Permissions.


If you're getting the properties and relationships of an attachment, the response body includes an attachment object.The properties of that type of attachment are returned: fileAttachment, itemAttachment,or referenceAttachment.


The next example uses the same request as in example 3 to get the properties of an item attachment on a message by using $expand. In this case, because the attached item also has a file attachment, the response includes the properties of the file attachment as well.


The response body includes the eventMessage attachment in MIME format. The body of the eventMessage is truncated for brevity. The full message body is returned from an actual call.


You need to specify the type of attachments (there can be three different types of Attachments in Exchange FileAttachment,ItemAttachment,ReferanceAttachment) and you also need to Base64Encode the contentBytes so in you example the following should work


It connects fine, it returns the first 10 unread emails, the .HasAttachments if statement only runs when there is an attachment but item.Attachments or item.Atttachments.CurrentPage is erroring with 'Object reference not set to an instance of an object.'






Do note that upload sessions should be used for uploading files that are greater than 3 MB in size. For file sizes lower than 3 MB, you can continue to do a single POST on the attachments navigation property of the message.


An email attachment is not being recognized as an attachment... I've even tried using the out of the box template available, if it has images, pdf, documents, etc it works fine, if you have an email attached thou it gets ignored, it doesn't even show as an attachment.


Reply from Microsoft Support Team indicate email are considered "attachment items" not "attachments" (however weird that sounds) and the connector does not recognize them as true attachments to be saved.


A suggestion of an API call is the closes to a solution (see replies for more info). An API call seems not to be able to process email .msg attachments either from what I gather on the reply from the Microsoft Support Team guy.




If you decide to go straight at the Graph API (e.g. using an Azure Function that gets invoked by your Flow), make sure you consider usage of the ?$expand=attachments parameter to get the nested message's properties included in your root call.


Next, you can construct our email and attachments using the matching PDF files you moved to the folder. You can then use Send-MgUserMail to email the requested user or group.


The following example shows you how to search for messages with attachments in the Inbox folder and download the attachments. We use here Query parameter to return messages based on conditions, in this case only messages with attachments.


Hi, I am working on this workflow, Image attached, I have 3 items in input, each contributes to a single attachment, so I have 3 attachments, but in output I see 9 attachment downloaded, could you please help what is wrong with it.


Raju_Botu Thanks for the response. I have gone through this article but not getting how we can do this from Pega end. Is there any configurations that we can do in Pega end to change the attachment size?


I have found the solution that I was looking for. The API call needs to return the attachment in this format:

As I mentioned in the article, attachments over 3MB require additional code. It seems Glen Scales recently wrote a function to take the guess work out of this. Check it out here: -message-with-large-attachment.html


I'm currently working on an Azure Logic App, and wanted to know how files/attachments appear within the JSON output of the graph api 'get incident' call. All of my test outputs so far have not contained any attachments within the emails, and I need to know how they actually appear in the JSON so as to properly process them. This is one of the outputs I have gotten (information redacted)


as you can see, this one has no attachments (attachmentsCount: 0) but as I said I need to know how they actually appear. My initial assumption was that they appear in an array similar to the URLs, but I have to be sure (especially since I do not know if they appear as their hashes or something else).


I've tried looking online for any information regarding what the HTTP call output with attachments looks like, with no luck. Microsoft documentation doesn't mention it, and I don't have access to an email/incident with attachments that I could test.


On the documentation page you see a JSON sample object with its properties. Of course you do not to include all these properties when you want to send a mail. Also the sample shows you how to send an attachment, but not how to embed an image. The answer for this can be found in the fileAttachment resource type documentation. Here are the essential properties you will need in your mail model:


Important: it is important to include the odata.type for your attachment. If you do not include it, your request ends up in a bad request. If you want to embed an image, it has to be set to #microsoft.graph.fileAttachment.


If you already developed an application in the past where you were required to embed images in mails. You will know you have to work with Content-ID or CID references in the HTML mark-up. Once these CID references are in place, you have to link the images as a resource and specify the CID per attachment. This is no different when working with the Microsoft Graph. As you can see in the model, you can also specify the contentId property to the attachment.


Important: in attachment I specify contentBytes and contentType of the image. ContentBytes is the binary contents of the file, also known as Base64. ContentType is the image type like image/png or image/jpeg.


If you want to try this application, you will first have to create an Azure AD application and fill in the Client ID and Redirect URL in the app.config file. You will also have to add your tenant ID. This can be the domain name (tenant.onmicrosoft.com) or the ID.


I'm trying to invoke MS Graph REST API to fetch email with attachment and that the attachment in response body location is fetched correctly but When specifying fv!result.body.value.name in 'Name', we get error as shown above. Does it accept only static names?


When sending an email with small attachments through exchange online using Microsoft Graph API, the attachments are being stripped off when the email is sent to the same domain as the sender (eg sending to myself). If sent outside the sending domain everything is OK. The email arrives but no attachments.


This is the code used to add the attachments, catering for 3MB, then send the email (draftMessage has already been setup with all necessary parameters, error handling stripped out for brevity):


A premium feature that is enabled by default is support for sending attachments larger than 3 MB from WordPress. To actual send large attachments, the plugin will first create a draft email and then upload one or more (large) attachments. For the plugin to be able to do this, you must update the API Permissions for your App registration in Azure AD and you must add Microsoft Graph > delegated > Mail.ReadWrite permissions (and confirm by clicking Grant admin consent for ...). Alternatively, you can add Microsoft Graph > application > Mail.ReadWrite permissions, but this is not recommended.


You can choose to send emails from a Microsoft 365 Shared Mailbox instead. If you select this option, the Default "From" address (mail account) must be one of the users that has access to the Shared Mailbox. Also, if you configured delegated permissions, you must update the API Permissions for your App registration in Azure AD and you must add Microsoft Graph > delegated > Mail.Send.Shared permissions (and confirm by clicking Grand admin consent for ...). If you expect to send large attachments from a Shared Mailbox then you must also add Microsoft Graph > delegated > Mail.ReadWrite.Shared permissions. If you configured application-level Mail.Send permissions then you will find that you can already sent email as any user from a Shared Mailbox and do not need to add any new permissions.


I recently worked on a task to send an email with an attachment using the Microsoft Graph API. I included the Microsoft Graph API script code at the end of my PowerShell script. The script sends an email to a specified email address with an attachment and also includes a table of contents in the body of the email.


Next, create a variable called $attachment and provide the path of the attachment you want to send with the email. For example: $attachment = "c:\temp\listofusers.csv". You can modify the location according to where your email attachment is stored.
