Download Outlook Email Attachments Using Microsoft Graph API In Python

In this tutorial, we will learn how to download email attachments in Outlook using Microsoft Graph API in Python.

So in the past, when I need to download Outlook email attachments automatically, I would have to rely on using VBA, but one limitation with that method is VBA only works on the Outlook desktop application. And since all the email messages are saved on the Microsoft’s exchange server, I need to retrieve emails locally first, then I can download the email attachments. Now, the problem is solved by using Microsoft Graph API to access my emails.

to those who have problems with the downloaded files, 1kb or if it is corrupt file, the problem is Jie forgot to add, headers=headers in line 17.

attachment_content = requests.get(
GRAPH_API_ENDPOINT + '/me/messages/{0}/attachments/{1}/$value'.format(message_id, attachment_id),
headers=headers
)

How can we set up the orderby param? For example, if I want to sort emails by receivedDateTime desc, how would I set up the string corresponding to that param?

[tridibbiswas]

Thanks a lot for the Video👏. Very Useful one. But I am getting exception.
Exception: {'error': {'code': 'Request_BadRequest', 'message': "Unrecognized query argument specified: 'top, select, filter, count'.

[somitmitra]

what is the maximum size of attachment that we can fetch from the Graph API endpoint ?

[clawlan]

Thanks for this. I am getting the following error in the flow variable: "No tenant-identifying information found in either the request or implied by any provided credentials". I'm assuming this means it wants me to pass the tenantID but I don't think generate_access_token() is set up for that. Any ideas?

Hi Jenn, thank you very much for the video. I was able to generate a token and download files with different extensions, however, when you open the downloaded attachments they only have the following: {"error":{"code":"InvalidAuthenticationToken", "message":"Access token is empty."}. Any help would be appreciated!
