Recipient, Domain, and Company Management

Office 365
 

Applies to: Office 365

Topic Last Modified: 2014-04-14

Microsoft Exchange Online Protection (EOP) offers several means of managing your recipient, domain, and company information. As an administrator, you can perform certain management tasks within the Exchange admin center (EAC), and verify other management tasks performed in the Microsoft Office 365 admin center.

Looking for information about all EOP features? See the Exchange Online Protection Service Description.

Mail recipients are categorized as mail users or groups and can be managed directly in the EAC. Users can also be managed through directory synchronization and in the Office 365 admin center. If you’re managing your recipients on-premises, you must run directory synchronization in order for your mail recipients to be reflected in the EAC. Users managed solely in the Office 365 admin center aren’t viewable in the EAC, but they can be added to or removed from membership in an administrator role group in the EAC. For more information about recipients in EOP, see Recipients in EOP.

In EOP, you can configure administrative roles only. Users can be added and removed from default admin role groups directly in the EAC. No RBAC customization is available. For more information, see Manage Admin Role Group Permissions in EOP.

Managed domains are domains that are protected by EOP. Managed domains can be viewed and domain types can be edited in the EAC. Domain provisioning and management occurs in the Office 365 admin center and changes are reflected in the EAC. For more information, see View or Edit Managed Domains in EOP.

In EOP, you can enable mail flow to subdomains of a managed domain. For more information, see View or Edit Managed Domains in EOP.

The Directory Based Edge Blocking feature lets you reject messages for invalid recipients at the service network perimeter. DBEB lets admins add mail-enabled recipients to Office 365 and block all messages sent to email addresses that aren’t present in Office 365. If a message is sent to a valid email address present in Office 365, the message continues through the rest of the service filtering layers (anti-malware, anti-spam, transport rules). If the address is not present, the service blocks the message before filtering even occurs, and a non-delivery report (NDR) is sent to the sender informing them that their message was not delivered.

Enabling DBEB requires some user and domain configuration. For more information, see Use Directory Based Edge Blocking to Reject Messages Sent to Invalid Recipients.
