There is no item specific event for new messages. As I said in a previous
post, you have to get an object for an individual item from the
Inspectors_NewInspector event. This fires for ALL items, new or existing.
You can use just about any event for an Item (in your case, the MailItem_Open
event) to determine whether the Item is new or not. For new items, the Sent
property is always False.
If you need to have the user select from a list of addresses, then it would
be best to build a UserForm that has a list box which you populate by
iterating through the AddressEntries collection from an AddressList object
obtained from the NameSpace.AddressLists collection. Otherwise, you can call
the same dialog that is used when you click the To: button by using the CDO
library. However, if you're not familiar with that object model it may be a
little more work for you than you'd like.

Dear Eric,
I just want to thank you again for all your help. Your posts and blog have
answered all of my questions and pointed me to where I can learn more.
Your few answers have taught me more in a few hours than I could have hoped
to learn from the on line help which would have taken me a few weeks (not to
bright you see). Given you (and all the others) do this for free is
fantastic.
Thanks
Carmi
