Microsoft's cloud email service providing business email, calendar, and contacts.
Exchange Online is Microsoft's cloud-hosted email service, providing business email, calendaring, contacts, and tasks. It's included in all Microsoft 365 business plans. Exchange Online offers large mailboxes (50-100GB depending on plan), shared mailboxes, resource booking, and integration with Outlook. Security features include Exchange Online Protection (EOP) for basic filtering, with Defender for Office 365 available for advanced protection.
Why It Matters
The DSC Perspective:
Exchange Online is likely where your email lives. Understanding its security features—and their limitations—helps ensure adequate protection. Basic Exchange Online Protection should be supplemented with Defender for Office 365 for better phishing protection.
