I'm having a hard time finding out whether or not MFA functionality is included in O365 Exchange Online P1 for users logging in to the e-mail environment.

 

If anybody knows, I'd also like to know where it's mentioned in official Microsoft Office 365 documentation.

Based on this, I’d say yes it is:

 

“Today we’re adding Multi-Factor Authentication for Office 365 to Office 365 Midsize Business, Enterprise plans, Academic plans, Nonprofit plans, and standalone Office 365 plans, including Exchange Online and SharePoint Online. This will allow organizations with these subscriptions to enable multi-factor authentication for their Office 365 users without requiring any additional purchase or subscription.”

 

https://www.microsoft.com/en-us/microsoft-365/blog/2014/02/10/multi-factor-authentication-for-office...

That's a great news article from 2014! I can't seem to find it explicitely in a more current service description, though.

Thanks!

Agreed, a more recent reference would be good, can’t see any mention in service descriptions, product literature or documentation, this was the closest: 

 

Q: Is there a free version of Azure Multi-Factor Authentication?

In some instances, yes.

Multi-Factor Authentication for Office 365 users offers a subset of Azure MFA features at no cost for access to Office 365 services, including Exchange Online and SharePoint Online. This offer applies to users who have an Office 365 license assigned, when the corresponding instance of Azure Active Directory doesn't have the full version of Azure MFA through an MFA license, a bundle, or a standalone consumption-based provider.

 

https://docs.microsoft.com/en-gb/azure/active-directory/authentication/multi-factor-authentication-f...

Thanks for the reply, it just isn't 100% clear to me whether or not a user licensed solely for Exchange Online P1 is also implied when talking about "Office 365 users" in this context.
Solution

I thought that too, I am reasonable sure though at this point that plan does include MFA but you might have to contact Microsoft directly somehow to get a definitive answer. From the product page there is a contact us option, in the UK at least, either via phone or with a form, or you could try asking via support perhaps if you already have Office 365.

The answer is yes. To login to any Office 365 app you are being authenticated by Azure AD. And MFA is a key part of 'Azure AD Free', which is what you get with any Office 365 licence. https://docs.microsoft.com/en-us/azure/active-directory/authentication/concept-mfa-licensing
