Restrict email access to Exchange Online
Hi all, I have a situation of a customer without an on-prem Active Directory, only using some cloud apps, like Office 365. They want to block access to (in first place) e-mail on non managed dev...
Hi Peter,
Have you tried this setting within Intune?
If you do not want to cover all platforms with generic policy you can also select specific platforms like below:
You also get a way to block OWA and ActiveSyn clients:
This will cover non-domain joined windows 7 also.
Let me know if this helps.

Hi Jasjit,
Thanks for the reply.
Yes tried that policy before, blocks OWA access and the use of the buildin mail app on Windows 10, but it still gives me access to Exchange Online by using Outlook 2016.
Also tried Conditional Access from the new Azure portal under Aure AD (in preview), same situation; blocking OWA and the buildin app, but still allows access via Outlook.I have enabled modern authentication for Exchange Online.
It now shows me a message access is blocked when I try to connect using Outlook, but is does that on domain joined Win10 devices as well.
I`m using Conditional Access from the new Azure Portal (https://blogs.technet.microsoft.com/enterprisemobility/2016/12/15/conditional-access-now-in-the-new-azure-portal/).Hi PKlapwijk,
Let me try that in my lab setup - that kinda sounds strange and I would think MS would have thought of this scenario you are trying to achieve - which is a common ask from other customers too I presume.
I will get back to you and let you know.

Jasjit
