Windows 7 removed Windows Mail (for no good reason). Provides no Windows Mail link to guide the user to "Windows Live Mail". When you find and configure "Windows Live Mail" it does not import your *.IAF files, contacts, or messages.
Import all users properly backed up Windows Mail data, including *.IAF, Messages, Contacts, etc.
Restore Windows Mail to Windows 7 without delay. It may be understandable to not improve Windows Mail going forward, but it is customer hostile to remove it for no reason.
