Inline images not recognized as attachment

My code basically looks like this:

    for att in message.attachments:
            att.save(att_path)

This recognizes all attachments, including inline images, and adds them to a folder. But this only works if the e-mail has actual separate attachments (i.e. you see the paperclip). If the email ónly contains inline image (pasted images, company logo’s) it won’t add any attachments.

If I had a if message.has_attachment() in my code this would make sense, but I don’t. How do I fix this?

Ok, I’ve found the issue.

The Graph docs says that the property ‘hasAttachments’:

Indicates whether the message has attachments. This property doesn’t include inline attachments, so if a message contains only inline attachments, this property is false. To verify the existence of inline attachments, parse the body property to look for a src attribute, such as .

Ok. so:

1. When creating the message instance, if the ‘hasAttachments’ property informed by the server is False, the O365 library will have to inspect the body (in case it’s html) and check if there are img tags with source that starts with ‘cid:’.
2. If there’s something then change the ‘hasAttachments’ to True.

With these steps It should work.

Here is an e-mail with just 3 inline images:

Here is that same e-mail with one more image (hackerman.png) added as an attachment:

So now it suddenly recognizes all attachments, incl inline images. So it really seems to me that there is some kind of check for attachments in Python O365 that is causing this behavior. Unless of course Azure O365 is handling e-mails with attachments differently than those without.
