An XML file containing the plist snippets (<dict>...</dict>) you can optionally deploy via Custom XML payloads in order to bypass the screens shown on first-run of Microsoft Office applications, as well as control how updates to Office applications are applied via Microsoft AutoUpdate.
NOTE: You must paste each snippet into its own payload - you cannot paste the entire file into a single custom XML payload.
IMPORTANT: The Microsoft AutoUpdate snippet enables background auto-updates and disables the checkbox for "Insider" builds.
