New Outlook for iOS and Android App Config Policy Experience in Intune - Account Setup Config

i love to see the progress. as we are speaking about intune and its capabilities to manage the outlook mobile app. a customer of mine, with exchange on-premises and the exchange connector deployed. Wants/Needs to utilize the conditional access capabilities - to block all unmanaged devices from synchronizing. He really wants to introduce the outlook mobile app as company mail client on their phones, but as of my last testing’s he can’t. Because the conditional access policies from the on-premises connector blocks the active sync device partnership, even if the outlook mail profile is configured through intune (legacy configuration keys were used). The conditional access policy currently allows only the native mail apps (iOS Mail, GMail and Nine for Work). Is this still “as is” or are there some more hidden features with this new app configuration experience? Thanks, and cheers
