We are looking to enable HMA to allow secured external access to Exchange on prem for iOS and Windows 10. iOS isn't a problem here, we understand the change to end user experience. For Windows 10, Outlook currently tunnels through a VPN to CAS. Users still leverage EAS basic auth, so we are not entirely sure how enabling HMA will change this flow.
Time and means unfortunately doesn't permit us to create a lab in which to carry out extensive testing.
Might anyone have encountered a similar challenge or provide insight as to the 'known' change in flow?
Thanks,
