Outlook Security does not seem to be consistant

[HJ]

I don't understand the inconsistancy that Outlook uses in keeping its
address information secure.

For example, when I do File, Send To, Routing Recipient, Outlook
brings up the security message warning me that someone is trying to
access information from Outlook.

But if I do File, Send To, Mail Recipient - I don't get any warning
messages even though I can run this task using VBA code and have the
email sent off without the user knowing anything about it.

Also if I use vba code like this to get the details on a person:

sResponse = Application.GetAddress(name:=frm.txtFirstName.Text _
& frm.txtLastName.Text,
AddressProperties:=sAddressProperties, _
CheckNamesDialog:=True)

I can get the information without any security message displaying.

Can someone explain why using application.getaddress doesn't cause any
security warning to show up?

Thanks
