Microsoft Exchange is a server-based messaging platform that handles email, calendars, contacts, and tasks for businesses. It operates as the backend infrastructure, managing mail flow, storage, and security. Exchange Online, the cloud-based version included in Microsoft 365, eliminates the need for on-premises servers while delivering enterprise-grade reliability with 99.9% uptime guarantees. Key features include large mailboxes (typically 50-100 GB), advanced spam and malware filtering, data loss prevention, and eDiscovery for compliance requirements.
Microsoft Outlook serves as the primary client application for accessing Exchange services. Available as a desktop application, web-based Outlook on the web (OWA), and mobile apps for iOS and Android, Outlook provides a unified interface for managing communications. Users can organize emails with folders, rules, and focused inbox features that prioritize important messages.
The calendaring functionality enables users to schedule meetings, book resources like conference rooms, and share availability with colleagues. The Scheduling Assistant helps find optimal meeting times by displaying participants' free and busy status. Calendar sharing allows teams to view each other's schedules, improving coordination and reducing scheduling conflicts.
Integration between Exchange and Outlook extends to shared mailboxes for team collaboration, distribution groups for sending messages to multiple recipients, and public folders for sharing information across organizations. The platform also supports room and equipment mailboxes for managing physical resources.
Security features include multi-factor authentication, encryption for messages in transit and at rest, and advanced threat protection against phishing attempts. Administrators can implement retention policies and archiving to meet regulatory compliance requirements.
Together, Exchange and Outlook deliver a comprehensive communication solution that scales from small businesses to large enterprises, enabling productive collaboration across any device or location.

Exchange Online operates in Microsoft's cloud data centers. When a user sends an email, it routes through Exchange Online servers, which handle delivery, security scanning, and storage. The service synchronizes across all devices where the user has Outlook configured.
For calendaring, Exchange stores calendar data centrally, allowing users to share calendars, book meetings, check availability through the scheduling assistant, and manage room and resource bookings. Calendar items sync across Outlook desktop, mobile, and web clients in real-time.
