Exchange

What is Exchange?

Microsoft Exchange is a mail and calendaring server developed by Microsoft that powers email communication, scheduling, contact management, and task tracking within organizations. It’s the backend technology that works behind applications like Outlook and integrates seamlessly with Microsoft 365 services.

Exchange delivers a highly reliable and scalable enterprise-grade messaging platform. It supports both cloud-based (Exchange Online) and on-premises (Exchange Server) deployments.

Why Use Exchange?

Microsoft Exchange is the backbone of professional email in Microsoft 365. Here's why organizations rely on it:

• Enterprise Email Infrastructure: Manage email at scale with advanced filtering, policies, and security.
• Built-In Calendars: Efficient scheduling, shared calendars, and meeting coordination.
• Anywhere Access: Accessible from desktop apps, web browsers, and mobile devices.
• Security and Compliance: Built-in data loss prevention, encryption, and retention policies.
• Global Address List (GAL): Company-wide directory of users, groups, and contacts.

Whether for small businesses or large enterprises, Exchange offers a secure, robust, and highly integrated email solution.

Is Exchange Free?

Microsoft Exchange is not available as a free standalone service, but it is included with several Microsoft 365 subscriptions:

• Exchange Online: Available with Microsoft 365 Business, E1, E3, E5, A1, A3, A5 plans.
• Exchange Online Plan 1/2: Can be licensed individually.
• ❌ Not Free: No standalone free version exists outside of trial access.
