Duo and Office 365 - securing office.com/portal.office.com


Hey folks, I got conditional access working for exchange online and sharepoint online, but I’m stumped as to how to get it working with portal.office.com or office.com where the majority of my users, especially Mac users land.


Here is my “me too” post. I swear I tested this a couple of months ago in a test tenant (Azure P1 with Conditional access). Originally every login to portal.office.com was protected. Now when I enabled Conditional Access I have to actually click on one of the App links on portal.office.com to see the duo page. According to MS documentation, enabling conditional access on exchange or sharepoint is also supposed to enable MFA on all of office.com


I had to create a CA policy to cover all cloud apps to protect portal and office.com.
