When viewing Microsoft Office documents in the Unity Client, the Integrated Office Viewer may be used. When the Unity Client is integrated with a Microsoft Office Online Server or Office for the web, Microsoft Office documents are viewed in the Integrated Office Viewer.
Documents flagged as read-only cannot be previewed during upload in the Integrated Office Viewer.
An additional button for viewing documents in a different viewer is available on the Document tab when viewing a document. For more information on opening a document in a different viewer instead of the Integrated Office Viewer, see Opening Documents in an Alternate Viewer.
If the Office Business Application is installed and the Integrated Office Viewer is configured, the Integrated Office Viewer takes precedence and the documents are viewed in the Integrated Office Viewer instead of the native Microsoft Office application.
