1.    Open office 365 on a browser and navigate to outlook.

2.    Navigate to the calendar at the bottom of the screen

3. Select the date that you would like to book the meeting for and double click

alternatively you can select "new event" and set the time and date accordingly

4. after all fields have been filled in, click "Search for a room or location", this will bring up a drop down menu, allowing you to select the correct room.

All other settings are the same as the outlook application, which you can find a guide for here:
