CDOEX is a superset of CDOSYS; this means that CDOEX contains all of the functionality of CDOSYS, plus additional functionality for use with Microsoft Exchange Server 2000. When CDOEX is installed on a computer, it takes over the functionality that was previously provided by CDOSYS. Any program that makes calls to CDOSYS will now call CDOEX instead.

An instance of the Configuration Component Object Model (COM) class is created and

You might have faced this issue if you have used Outlook to send emails to SMTP recipients (non-exchange). Whenever you attach any MSG file to attachments it gets converted to inline attachment for the recipients. It made my colleague Akash worried why its happening and I have to explain him Why. Here is the story... Outlook and Exchange both are responsible for content conversation on the basis of protocol being used. If it’s MAPI (Outlook connecting to Exchange), Outlook will not touch the
