Populating Locations for the Outlook Places Service

The Outlook Places service is used by Outlook clients to present metadata about meeting locations to users. Currently, OWA is the only client that consumes the service. You can update location metadata with details to make it easier for users to select the right location for their meeting, including geocoordinates that can be used to display map directions to the location.
