In Microsoft Outlook, go to the File menu and select New > Meeting.
Next to the Location field, click the button that looks like an open book.
In the window that pops up, search for the word “room” to see a list of available conference rooms. Select the room you want to reserve and hit “Add to meeting.”
The room will be added to both the To field and the Location field.
Set the meeting details (date, time, subject) and add any others you’d like to invite. When you send the email you’ll receive a confirmation that the room was successfully reserved.
