Block 3rd Party Mail/Calendar Apps
Hi all, Is it possible to block users from logging into their Office 365 accounts via 3rd party iOS apps such as MyMail which is found on the Appstore/Play Store ? Link to MyMail: https://itunes.apple.com/us/app/mymail-email-app/id722120997?mt=8 We're in the process of migrating all users to Outlook for iOS/Android. If corporate owned, they will enroll via the Company Portal app and have Outlook, Work, Excel, PowerPoint, Teams, OneDrive & Authenticator auto installed/pushed. If they are BYOD, I need them to only use Outlook for iOS/Android with an app password forced via Intune App Protection Policy. I've attempted disabling ActiveSync, + OWA for Devices within O365. No luck. Appreciate any input. Cheers Brett
