Exchange Online Protection features
The following table lists Exchange Online Protection (EOP) features that are available in Office 365 operated by 21Vianet plans. For more detailed information about EOP features, select the links in the table.
Note
The Office 365 operated by 21Vianet version of Office 365 is specific to China.
1 Mail users are defined as "Mailboxes," and, along with external mail contacts, can be added, removed, and otherwise managed directly in the Exchange admin center (EAC).
2 No RBAC customization. Admin roles only.
3 Managed domains can be viewed and domain types can be edited in the EAC. All other domain management must be done in the Microsoft 365 admin center.
4 Mail flow rules (also known as transport rules) in EOP are described in Mail flow rules (transport rules) in Exchange Online Protection. The available mail flow rule conditions, exceptions, and actions differ slightly between EOP and Exchange Online. These differences are noted in Mail flow rule conditions and exceptions (predicates) in Exchange Online and Mail flow rule actions in Exchange Online.
5 EOP auditing reports are a subset of Exchange Online auditing reports that exclude information about mailboxes.
6 The default content filter action is to move spam messages to the recipients' Junk Email folder. For this to work with on-premises Exchange mailboxes, you also need to configure two transport rules in your on-premises Exchange organization to detect spam headers added by EOP. For more information, see Ensure that spam is routed to each user's Junk Email folder.
7 This feature is available to Exchange Server 2013 Service Pack 1 (SP1) customers whose mailboxes are being filtered by EOP.
