The New Outlook represents a structural shift from Outlook Classic client to a web-aligned, service-connected architecture. For IT professionals supporting Microsoft 365 environments, understanding these changes is no longer optional.

This Level 300, full-day technical workshop is designed for intermediate IT administrators, support engineers, and Microsoft-focused professionals who are actively managing user transitions and troubleshooting New Outlook in production environments.

We will examine:

Architectural differences between Classic Outlook and New Outlook

Profile, account, and data handling changes

Exchange Online dependency and service-side behavior

Migration impact: what does not carry forward (PSTs, COM add-ins, VBA/macros, profiles)

Real-world ticket patterns and troubleshooting frameworks

This session assumes working knowledge of Microsoft 365, Exchange Online, and Outlook Classic. We will focus on operational impact, support readiness, and deployment considerations, not feature overviews.

Attendees will leave with a clear technical understanding of how the New Outlook operates, where architectural limitations exist, and how to proactively reduce support friction during adoption.
