This enables your users to leverage the Alfresco repository directly from Microsoft Office.
You can also use Microsoft Office SharePoint Protocol Support to enable online editing for Office documents within Alfresco Share. It enables your users to modify Office files without checking them in and out. Alfresco locks the file while it is being modified and releases the lock when the file is saved and closed.

The SharePoint Protocol Support architecture embeds a Jetty web server within the Alfresco repository. The Microsoft Office clients communicate directly with the Jetty server using WebDAV-like calls with proprietary extensions and on different port number from Alfresco Share. This port number can be configured in the SharePoint Protocol Support properties files.
