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/.
Sharing your ArcGIS Maps for Office layers to ArcGIS is a quick and easy way to share information with others in your organization or in the ArcGIS public community. You can share individual layers or the entire map.
When you share a layer, a hosted feature service is created on ArcGIS, where you can do more work on it.
