Question about spam

[Bupkus]

I just received this email forwarded for a family member.  I'm not 
forwarding it to this list for obvious reasons.

It's a promise that for every person I forward it to Microsoft will pay 
me $245.00.  For every person they send it to Microsoft will pay me an 
additional $245.00.  I figure it's a method for collecting current email 
address, but I don't know enough about email technology to fiure out how.

There doesn't seem to be an attachment but maybe that's because it uses 
an exploit found in outlook and i'm using Thunderbird.
I would think that it's success is dependent on adding an additional 
address to the forward list so it all goes back to the spammer.

Any way to figure this out?  I'm a little annoyed with my relative as 
I've told her to only use my child email address and she just used my 
master email address(the one I can't delete).  Thanks.
