Nicolás Bello Camilletti wrote a good guide on calling the Graph API with a Javascript function here: https://medium.com/southworks/calling-microsoft-graph-api-from-an-azure-function-using-javascript-3456e81345a1

There are a few steps to setting this up.

1. Setup a new app registration in Office365 to get a app Id and secret.
2. Give that app the permissions needed to read and write the values you need.
3. Use the ADAL npm package to obtain a token for the Graph API with those credentials.
4. Make your calls to the Graph API, using the bearer token in the Authentication header
5. Ensure your function.json file defines the trigger as a timer with a one day interval.
