OMG! This is a day I have been waiting for.
I do a LOT of Outlook Web Add-in development. A lot. I have made the move from Visual Studio to Visual Studio Code, from C# to JavaScript and have not looked back. However, there are a few things that make development in this new area difficult and that is rapid prototyping.
For C#, I could always go into VBA and see how the object model would behave when I needed to test a hypothesis. I was able to use VBA as a laboratory for ideas before I codified them into solid C# code in a VSTO Add-in. But there was no such laboratory in the JavaScript web add-in world, until now…
…Script Lab for Outlook has been released. And the best part, it is available in Outlook on Windows, Outlook on Mac and Outlook on the web!


If you do a lot of Outlook development this will be a godsend. You will now be able to go into Script Lab and test your code ideas before you add them to your more complex add-in.
Open Outlook, go into the Office Store and type “Script Lab” and Script Lab for Outlook should come up in your list. Select and install it. Then open a message in Outlook and you should see the Script Lab items on the Home tab.
Happy coding!
