In AirWatch 8.4, some Windows Phone 10 devices fail to install certain apps from the Business Store Portal (BSP). When this issue occurs, devices will show error code 2147009285. The Device Services logs will display the following error:
Deployment of package <Package> was blocked because the provided package has the same identity as an already-installed package but the contents are different. Increment the version number of the package to be installed, or remove the old package for every user on the system before installing this package.
This issue has been resolved in AirWatch 9.0.
