Implement Microsoft authentication and email integration

Job ID: 35437514

Budget: £36 – £0 GBP

The system currently uses forms authentication and is hosted on Azure. One of our customers required the system to use Microsoft (Outlook/Live) authentication with 2FA.
The system also need to send emails using the same criteria.

I have currently tried to implement this using OAuth2/Owin connecting to an Azure Active Directory application but have faced several issues. So I need an expert in the field for one-to-one help with the implementation.
