Is there a way to impersonate a user in office 365 using the new Microsoft Graph API?
I am currently using EWS API to impersonate office 365 users to add calendar events.

The Microsoft Graph uses OAuth2.0, and so you can have your app operate as the signed-in user, if the user grants the app the ability (in your case) to read/write calendar events. (In OAuth2.0 this flow is known as the code flow). If you need your app to create events on behalf of many users, where the user is not actually signed in to your app - say your app is a daemon service of some sort - then you could use the OAuth2.0 app-only (client credential) flow. Acquiring delegated access token to call Microsoft Graph is documented here: https://docs.microsoft.com/azure/active-directory/develop/v2-oauth2-client-creds-grant-flow
Hope this helps,
