• Basic cmdlets that are also available in Exchange Online PowerShell (for example, Get-User, and Get-RoleGroup).

• A few cmdlets that correspond to security features available in Exchange Online Protection (EOP) and Microsoft Defender for Office 365 in the Microsoft Defender portal (for example, Set-SecOpsOverridePolicy).

  Cmdlets for most EOP and Defender for Office 365 security features (for example, anti-spam policies) are available only in Exchange Online PowerShell.
