What is the Outlook COM Add-in Development for Enterprise course about?

Engineers building Outlook integrations face increasing pressure from shifting Microsoft policies, security audits, and enterprise compliance demands. Many assume COM add-ins are being phased out , but the real issue is outdated design. Unsupported patterns lead to instability, rejection from IT gatekeepers, and wasted development cycles. Without a structured, modern approach, even working add-ins face deprecation through policy, not announcement.
