By default, when you open a new meeting form in Microsoft Outlook 2016, Microsoft Outlook 2013, or Microsoft Outlook 2010, the Office Room Finder panel is displayed on the right side of the Appointment screen and the Scheduling Assistant screen, as shown in the following screenshots.
By clicking the Room Finder control in the Options group of the Ribbon, you can hide the Office Room Finder.
However, the Office Room Finder remains hidden only if you hide it on the Appointment screen. If you try to hide it on the Scheduling Assistant screen, and then you switch to the Appointment screen and then back to the Scheduling Assistant screen, the Office Room Finder is visible again.
