Due to the widespread of worms and virii, Microsoft did implement a security lock down on e-mail since 2002. This also includes the lock down on the programmatic access of e-mail. First, e-mails cannot be sent through Outlook, Outlook Express, MAPI or even CDO (if it depends on MAPI). Second, access to e-mail in Inbox through API has been limited as well. Third, some certain attachment types cannot be opened inside Outlook.

This has created a lot of problems in automating e-mail sending and receiving solution. However, Microsoft has some workarounds. Some of them are good and some of them are bad (either not helping much or too hard to use). They can be briefed as follows:

1. New  CDO 1.2.1 which is not based on MAPI anymore on SMTP side. This allows developers to send out e-mail programmatically without user intervention. This works pretty well.

2. However, you can use it to get information about e-mail in inbox as well as contacts, appointments, etc. with limited capability if “no” client intervention is a must. See http://support.microsoft.com/kb/262701/EN-US/ for more information.

Note: there is a workaround but it is pretty difficult to configure.. http://support.microsoft.com/kb/263297/EN-US/
