This little Slack Bot connects your Office 365 Calendar with your team Slack account to check if you're out of office. To set yourself 'out of office' simply place a meeting on your calendar with the subject 'OOO' or 'OOF' and this bot will let any teammates who @mention you that you're out of of office.
Create a file called .config.json and fill it out with your application secrets. You can also make each property an environment variable.

To run the app just do npm start, navigate to http://localhost:3000/login to authenticate to your Office 365 account. Create an event on your calendar - marking your vacation time with 'OOO' or 'OOF' in the title and an optional message in the event body. This slack bot will do the rest - letting your teammates know when you're out of office.
