I have kinda similar problem, but the error I receive is `requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: https://graph.microsoft.com/v1.0/me/sendMail | Error Message: Cannot send this mail due to a transient...

Here is the code I use to do it ``` def parse_attachment(dir_path, att): try: if (att == None): return None content = urllib.urlopen(att.file.url, timeout = 10).read() with open(os.path.join(dir_path, att.file.name), 'wb')...

@janscas Yea, thats a weird error. I solved it by adding exponential backoff retry as was recommended on microsoft graph api page.

@kwollaston I can help with the PR, did you create a branch for MSAL?
