Mail and calendaring server.

The overview

What Microsoft Exchange is for

Microsoft Exchange provides the foundational server-side infrastructure for enterprise email, calendaring, and contact management. As a 'website tool,' it primarily manifests through the Exchange Admin Center (EAC) for IT professionals managing the environment, and Outlook on the Web (OWA) for end-users accessing their mailboxes via a browser. The web-first workflow enables administrators to configure mail flow, security policies, and user mailboxes from any modern browser, while users gain ubiquitous access to their communication and scheduling tools without client software installation. This dual web interface approach ensures operational control and user accessibility are maintained across diverse network environments.

Quick answers

Frequently asked questions

1What are the primary differences between Exchange Server (on-premises) and Exchange Online?⌄

Exchange Server is deployed and managed within your organization's own data center, requiring you to handle hardware, software updates, and security. Exchange Online is a cloud-based service managed by Microsoft, offered as part of Microsoft 365 subscriptions, reducing operational overhead and providing automatic updates and scalability. Both offer similar core email, calendaring, and contact functionalities, accessible via OWA and client applications.

2Can I integrate Exchange with non-Microsoft applications or services?⌄

Yes, Exchange supports various integration methods. It provides Exchange Web Services (EWS) and a modern REST API for programmatic access to mailbox data, calendaring, and contacts, allowing custom application development. It also supports standard protocols like IMAP, POP3, and SMTP for basic mail client connectivity, and can integrate with third-party archiving, CRM, or security solutions via connectors and APIs.

3What are the browser compatibility requirements for Outlook on the Web (OWA) and the Exchange Admin Center (EAC)?⌄

Both OWA and EAC are designed for modern web browsers. For optimal experience, Microsoft recommends using the latest versions of Microsoft Edge, Chrome, Firefox, or Safari. While older browsers might offer limited functionality, full feature sets and security updates are ensured with current browser releases. Specific version requirements are detailed in Microsoft's official documentation for each Exchange version.

4How does Exchange handle data retention and legal hold requirements?⌄

Exchange offers robust features for data retention and legal hold. Through the EAC, administrators can configure retention policies that automatically move or delete items after a specified period. In-Place Hold and Litigation Hold functionalities allow specific mailboxes or items to be preserved indefinitely or for a defined duration, preventing deletion or tampering, which is crucial for eDiscovery and compliance with legal obligations.

5What is the recommended approach for migrating from an older Exchange version to a newer one, or to Exchange Online?⌄

For on-premises upgrades, a phased migration or cutover approach is common, often involving setting up a new Exchange server alongside the old one and migrating mailboxes. For moving to Exchange Online, Microsoft provides several migration paths: cutover migration (for smaller organizations), staged migration (for larger organizations with Exchange 2003/2007), hybrid migration (for seamless integration and phased moves), and IMAP migration (for non-Exchange sources). The Hybrid Configuration Wizard in EAC is key fo
