A friend forwarded a contact list to my gmail account from Outlook (2007 or 2010, not sure which). I can see there is an attachment in gmail but when I save it to my local drive it's just a plain text file containing the text This attachment is a MAPI 1.0 embedded message and is not supported by this mail system.

If I use gmail's "show original message" it contains in part:

This is a multipart message in MIME format.

How do I

1. save the attached winmail.dat properly, and
2. open the winmail.dat and extract the contact list?

I'm running Windows 7 x64, but have access to an ubuntu linux vmware appliance if needed. I have Outlook 2010, but can't use it to connect directly to gmail as pop3 and imap are blocked by the corporate firewall.
