Understanding Best Email Clients and Their Benefits for Connecting to Exchange Online


Introduction

This article describes the benefits of using Exchange Online and the recommended operating system/client combinations that support it.

Explanation

Microsoft Exchange Online is a cloud-based email and calendaring service that is part of Microsoft 365. It offers a dependable, secure, and collaborative way to manage email, calendar, contacts, and room resources. In 2016, the university shifted from Exchange on-premises to Exchange Online to leverage the scalability and security of the cloud service. In 2023 to 2024, the university shifted all email users except alumni to Exchange Online.

To take full advantage of Exchange Online, desktop users will need to use a supported Messaging Application Programming Interface (MAPI)-capable email client.

IMAP and POP3 connection methods are not supported in VT's Exchange Online environment. The supported Outlook email clients using the MAPI connection method provide a more secure and feature rich user experience to include:

  • Performance and synchronization improvements: With direct server-to-client communication users will experience less delays in receiving messages and better synchronization.
  • Enhanced support and management: Supporting consistent configurations across MAPI clients can improve security, compliance, and centralized management.
  • Security: using MAPI clients ensures support of advanced security features like integrated multi-factor authentication (MFA) and best security policy practices including data-loss prevention (DLP) mechanisms.

Advanced integration: these clients also offer more comprehensive integration with Microsoft's ecosystem, including features like offline access, rich calendaring, and advanced mailbox capabilities.
