Introduction
While brewing on a much more detailed post on how I moved my devices from Intune Hybrid with ConfigMgr to Intune standalone, I thought I’d share how you can offer webmail for your users, while requiring MFA (Multifactor Authentication) if not coming from a company device, using Conditional Access.
In this post I will only cover the actual steps in Intune, but for this to work, you will have to have your Windows devices registered with Azure AD. There will be some requirement for your on-prem AD and for your ADFS, if that’s how you federate with Azure/O365. These requirements are explained in details in this Microsoft article: https://docs.microsoft.com/da-dk/azure/active-directory/device-management-hybrid-azuread-joined-devices-setup
