Operating Principle of Owa-Notifier

Microsoft API credential obtaining

To request MS API, owa-notifier daemon need a oauth2 token from Microsoft. To obtain this oauth2 token, the daemon start :

• A browser to redirect user on authentication page
• A local webserver to handle user after authentication.

After a success authentication user is redirected to a local webserver with POST request-data containing a token. The local webserver store this token in memory for future usage and redirect user to OWA.
