Frequently Asked Questions
What is Exchange Online in Microsoft 365?
Exchange Online is the cloud-based email, calendar, and contact management service that powers Microsoft 365, running entirely on Microsoft's secure servers instead of on-premises hardware.
How do SPF, DKIM, and DMARC protect my email?
SPF, DKIM, and DMARC are DNS-based email authentication protocols that work together to verify sender identity, prevent spoofing, and ensure unauthorized users cannot send emails on behalf of your domain.
What is the difference between a hybrid and cloud-only Exchange deployment?
A cloud-only setup moves all mailboxes directly to Exchange Online, while a hybrid deployment connects your existing on-premises Exchange servers with the cloud to support gradual migration and co-existence.
