Demystifying Office 365 installation for Windows 10 from Intune – Cloud First
I’m writing this blogpost to help understanding what happens when you are deploying Office Pro Plus on a Intune managed device. First of all Office 365 installation is not a application installation in traditional sense!! It is not the same as a Win32 app deployed from Intune that are using the Intune Management extension (IME) or MSI LOB app deployment that are using the build-in MDM stack in Windows 10.
Office Pro Plus installation from Intune is a policy – a CSP policy

That is also the reason why you cannot create a dependencies from a Win32 app installation, on a Office Pro Plus app in Intune. The example I often get is, can we create a Win32 app that are installing a plugin for Office only if Office is already installed.
Trouble shooting is also different for Office Pro Plus installation as you need to look for different thinks on the end user device and not in the IME logs.

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OfficeCSP
In the Default key there is a link to http://go.microsoft.com/fwlink/?LinkID=829801 – that link point to installation of setup.exe

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OfficeCSP\9725059b-1892-443f-bee1-509ca15c0c16
In Default you can see the configuration.xml file that are used to install Office Pro Plus

Here is the default configuration.xml from the Intune installation. If you need other settings in your installation you can upload a custom configuration.xml file into Intune.

FinalStatus:
- When status = 0: 70 (succeeded)
- When status != 0: 60 (failed)

In file:///C:/Users/Public/Documents/MDMDiagnostics/MDMDiagReport.html you can also see that Office is installed

The end user will also get a notification when you Office Pro Plus is finish installing.

Happy deployment
