This post explains how to fix an issue that causes only the text System.string[] being displayed in a new K2 Appit task notification email.
It happens when any part of the notification contains a SharePoint property that is of type User. The obvious fix is to map this SharePoint field’s value to a K2 data field and use that in the email.
