Product Details: Microsoft Exchange Online Protection Subscription
The Microsoft Exchange Online Protection (EOP) subscription is a cloud-based email filtering service that helps protect your organisation against spam and malware, and includes features to safeguard your organisation from messaging-policy violations.
EOP can simplify the management of your messaging environment and alleviate many of the burdens that come with maintaining on-premises hardware and software.
The following list describes the primary ways you can use EOP for messaging protection:
In a standalone scenario: EOP provides cloud-based email protection for your on-premises email environment (Exchange Server or other on-premises SMTP email solutions).
As a part of Microsoft Exchange Online: By default, EOP protects Exchange Online cloud-hosted mailboxes. To learn more about Exchange Online, see the Exchange Online service description.
In a hybrid deployment: EOP can be configured to protect your messaging environment and control mail routing when you have a mix of on-premises and cloud mailboxes.
