This is an archive related to a previous version of ArcGIS Maps for Office. If you need the current version go to http://doc.arcgis.com/en/maps-for-office/.
For layers you've added from ArcGIS or layers you've shared on ArcGIS, you can access information about the item on ArcGIS. The information associated with the layer may include a description, access use and constraints, tags, service credits, size, and extent.
If the Layer details button isn't enabled, the selected layer does not have information accessible from ArcGIS.
The ArcGIS details page for the layer opens in your default web browser. If you're viewing details for a layer that is not shared publically, you are prompted to log in to ArcGIS.
