When deploying out Office 365 ProPlus to a VMWare device I received the following error in the SMSTS log file:
Failed to run the action: Install Office 365 ProPlus – VDI.
Unknown error (Error: 8007426C; Source: Unknown)
The execmgr.log file shed a little more light on the situation with the error:
Script for Package:<PackageID>, Program: Install Office 365 – VDI failed with exit code 17004
This error related to a lack of space remaining on the device. There was 4GB left from a 32GB provisioned device but it seemed that the Office install didn’t like that. A quick reconfiguration of the disk space to 60GB solved the problem.
