I'm trying to specify the account for an outgoing Outlook mail item but there doesn't seem to be a property for the mail item. I'm using Delphi 7 and an Outlook8.pas file. From searching the internet it appears that the property SendUsingAccount is only available from Outlook 2007 onwards.

How can I get source code or a component to give me access through Delphi to set this property or alternatively I've read that it is possible to set the Accounts setting through using the mail item Inspector, if anyone has done this, how do you do it?
