Microsoft Office 365 is an excellent tool for meetings. It has some basic functions for booking meeting rooms. However, it is not convenient to book a meeting together with meeting rooms in Office 365. WOX for Office 365 makes it one click to book rooms together with the meeting itself. It also allows for ad-hoc room booking and data is synchronized back to Office 365 to prevent double booking. In essence, if you have meeting rooms, you should integrate WOX with Outlook.

Absolutely. Although Enterprise Application is the way of future, WOX supports using Service Account to set up integrations. This makes it compatible with most companies' IT policy. You can always switch to Enterprise Application integration in future.
