Microsoft OneDrive move may facilitate accidental sensitive file exfiltration

The apparent intent of the Microsoft plan is to facilitate corporate workers who want to conduct a little personal activity while at work, something to help slightly with work-life balance. But IT leaders are not thrilled about having employee medical records, tax documents and private—sometimes very private—photos and videos on enterprise systems. 

The problem is potentially worse when the dataflow is reversed. Once those personal and corporate datasets are synced, it becomes inevitable that someone will accidentally save a sensitive corporate file to their personal OneDrive, which will then save the file on their personal computer.

To be fair, Microsoft has made it easy for IT to disable these abilities, but the default is that it will be allowed.
