A2007 working with Outlook 2007

[John]

Have a situation in which a notification email is sent from the A2007
front end (backend is sql2005) to a recipient that is to approve a
purchase order. The questions I have is whether or not it is possible
for Access to put on the email a link that would take the recipient to
our internet and pass the purchase order as a parameter to the
specified purchase order for more detail? If so, any example sites to
look at? The other question is on the same email to put another link
that the recipient would use to send back to the user an approval
email with much of the same info? If so, any example sites to look
at?
Thanks.
John
