With the newest release of Microsoft Office, we need to add few more lines to disable What's new prompt at first launch.
/usr/bin/defaults write /Library/Preferences/com.microsoft.Excel ONWhatsNewShownItemIds -array-add -int 17090
/usr/bin/defaults write /Library/Preferences/com.microsoft.Excel ShowWhatsNewOnLaunch -bool false
/usr/bin/defaults write /Library/Preferences/com.microsoft.Excel OUIWhatsNewShownItemIds -array-add -int 17091
The same for word,powerpoint,onenote,outlook.Hope this helps.

Note that setting these keys will not suppress the What's New dialogs on first launch of these apps, but will suppress the successive 'release notes' What's New dialogs.
