Office 2016 shuffled a few minor things around, as it usually does. And while preparing our users to enjoy their Office 2016 experience, admins would like to suppress those dialogs. To do so, we’ll need to write the kSubUIAppCompletedFirstRunSetup1507 key as boolean and true into each of the /Library/Preferences files for Office in OS X (e.g. com.microsoft.Word.plist). Here’s a quick scriptable that will take care of that for ya’:
defaults write /Library/Preferences/com.microsoft.Word kSubUIAppCompletedFirstRunSetup1507 -bool true
defaults write /Library/Preferences/com.microsoft.Outlook kSubUIAppCompletedFirstRunSetup1507 -bool true
defaults write /Library/Preferences/com.microsoft.PowerPoint kSubUIAppCompletedFirstRunSetup1507 -bool true
defaults write /Library/Preferences/com.microsoft.Excel kSubUIAppCompletedFirstRunSetup1507 -bool true
defaults write /Library/Preferences/com.microsoft.Word kSubUIAppCompletedFirstRunSetup1507 -bool true
Update on October 29, 2015: A user may have already received a key in ~/Library/Containers/com.microsoft.Word/Data/Library/Preferences/com.microsoft.Excel.plist, ~/Library/Containers/com.microsoft.Word/Data/Library/Preferences/com.microsoft.Word.plist, ~/Library/Containers/com.microsoft.Word/Data/Library/Preferences/com.microsoft.PowerPoint.plist, or
~/Library/Containers/com.microsoft.Word/Data/Library/Preferences/com.microsoft.Outlook.plist and if so if those are set to False you may need to remove them.
