By default, InfoPath property promotion is enabled. This setting allows you to disable the ability to promote InfoPath forms properties into Outlook properties. This feature allows InfoPath forms to promote properties from the underlying data into named properties in Outlook. These properties are displayed in views on folders, and users can group, filter, and sort by them.
