Script Lab for Outlook has three main features:
Run the code in the task pane beside your email or appointment. You can include logic, API calls to Office, UI in the pane, and even output to a console. Every time you make a code change, the editor refreshes, and you can run the new version in seconds.
Share your snippets through GitHub. If you create a snippet you’d like to share, you can use Script Lab to save it then send the link to someone else for them to try it and tweak it on their computer. The Import feature lets you load other people’s snippets. We think sharing will be especially useful for asking and answering questions about add-ins on Stack Overflow (tag office-js on general add-ins questions or outlook-web-addins on Outlook add-ins questions).
Right now, you can install Script Lab for Outlook, free from the Office Store. It works in Outlook 2013 and later on Windows, and Outlook 2016 and later on Mac. Currently in, the add-in is only supported in Chrome, Microsoft Edge, and Safari.
The following are a few screenshots to get you oriented on each platform:
