Why can't I perform a lookup room or person?

[Windows Central Question]

When creating a meeting on my Nokia 625 running Windows phone 8.1, it doesn't give me the ability to see if a room is available at a certain time or if a person is available. You can book in a room or person but you don't know whether they're available at the time of booking.

Surely there is something I am missing??

Thanks in advance for you help/advice.
