I have sent out my contact information as a vcard. Instead of
receiving it as a vcard, the person that I sent it to received it as
an attached e-mail. The icon of the attachment was that of an e-mail
and when you opened it up, the vcard was in e-mail format as well.

I have come across this issue before and would like to now how to
avoid or solve it.  It happens with great irregularity, so I am not
sure if there are any consistencies. In the most recent case, I sent
an e-mail with an attached vcard from my exchange server account using
Outlook 2003 to someone on another exchange server with an Outlook
2002 account.
