r/Office365 on Reddit: Does Office 365 E3 license include Microsoft Defender for Office 365?
February 6, 2020 -

Hello everyone,

I'm doing some research on MS documentation to find if I have the features of Microsoft Defender for Office 365 Plan 1 in my E3 license (Ex: Safe Links)

I did find that, but nothing is mentioning E3:

  • Microsoft Defender for Office 365 Plan 2 is included in Office 365 E5, Office 365 A5, Microsoft 365 E5 Security, and Microsoft 365 E5.

  • Microsoft Defender for Office 365 Plan 1 is included in Microsoft 365 Business Premium.

  • Microsoft Defender for Office 365 Plan 1 and Microsoft Defender for Office 365 Plan 2 are each available as an add-on for certain subscriptions. To learn more, see Feature availability across Microsoft Defender for Office 365 plans.

  • The Safe Documents feature is only available to users with the Microsoft 365 E5 or Microsoft 365 E5 Security licenses (not included in Microsoft Defender for Office 365 plans).

And especially the line in bold, the Plan 1 is included with Business Premium, so I guess it's included with E3?

Thanks! :)
