PIM items sent from the Windows 7 operating system cannot be received correctly
Symptom: Personal Information Manager (PIM) items sent from the Windows 7 operating system cannot be
received correctly into the address book of any other Bluetooth-enabled device.
Action: The Windows 7 operating system sends PIM items in XML format, but most Bluetooth-enabled
devices handle PIM items in vCard format. If another Bluetooth-enabled device can receive a le through
Bluetooth, a PIM item sent from the Windows 7 operating system might be saved as a le with the extension
.contact.
