I have tried out the Cloud Storage Encryption features on the MWG and it works great with the consumer version of Microsoft's OneDrive. However, the enterprise version of OneDrive does not seem to work with the cloud storage encryption. I've done rule traces and it does not seem to catch on the application control rule set.
Is there any possibility of cloud storage encryption being extended to the OneDrive enterprise platform?
since the cloud storage encryption is pretty much done "in the product" rather than in rules you will most likely need to file an FMR. Please follow the instructions on McAfee KnowledgeBase - How to submit a Product Enhancement Request (PER) to do so.
