access mail inbox using python

I'd like to write a python script that access my email at work (it's accessible from anywhere). So, we're using a browser-based email client called OWA, here's a small documentation of that (https://docs.microsoft.com/en-us/exchange/troubleshoot/owa/set-up-web-access) The webpage for work email is something like (mail.something.com/owa/), then it asks for the credentials which I use to access my company's computer. Things to note we don't have a POP3 or IMAP, we can access the email only through this domain and login with our credentials. **So, I need to know what library do I have to use to access my email through the link (mail.something.com/owa/) to read my inbox and download attachments?**
