When registering your app (or in the app's settings afterwards), specify `https://localhost:3993` as a redirect url and API permissions for the app should be at least `IMAP.AccessAsUser.All`. Also make sure to select `ID tokens (used for implicit and hybrid flows)` in the app's authentication settings. + +Create a `.env` file in this example's directory filling in the required data (`.env.sample` has got an exhaustive list of variables needed for this example to work). + +You can now hit `cargo run --example outlook_oauth2` from the repo's root and visit `https://localhost:3993` in your browser.
