You need to do a few extra steps to the room profile so you get the
conflicting notice without sending the email.

1. Open the room profile in Outlook
2. Go to Tools | Options and Calendar Option
3. Click on Resource Scheduling button
4. Check the boxes “Automatically accept meeting requests…” and
“Automatically decline conflicting meeting requests

this will get your the pop up message of conflicting meeting and keep the
message unsent.
