I want to create a facility in Outlook so users can save e-mails in the right place on our system by clicking a button on the Outlook control panel. The program will then look up the e-mail address in a DB and use that to work out where to put it.

I would do it through VBA, but it has to run on Outlook 2000, and virus warnings come up as soon as I try to access the properties of the MailItem. Microsoft advise that you can avoid this by using a COM add-in made in VB. Problem is, I'm not sure what that is. VB 6 Pro has the option to create an 'AddIn' project, but that seems to be for customising VB itself.

I think I need to make an ActiveX DLL, then reference it from an Outlook VBA macro with something like Set SaveThisEmailRoutine = Server.CreateObject("myDLL.SaveEmailRoutine")

That way I'm hoping that when the DLL interacts with the MailItem, it won't go confusing my poor users with messages about viruses.

Can anyone tell me if I'm heading in the right direction, or is this a load of old cobblers?
