In case you missed it, Microsoft recently announced the Microsoft Intune Company Portal app for iOS will be updated. Why this might be important to you?
As Apple releases new versions of iOS, they release new functionality, so there is a lack of functionality available on older iOS versions. Ending support for these older versions and encouraging end users to upgrade leads to a better end-user experience and allows us to prioritize the release new functionality for customers. This adjustment to support iOS 8.0 and later brings the iOS Company Portal app into alignment with the version support of the Office apps and many other Microsoft (and non-Microsoft) apps
