In a sign of how automation based on signals gathered by Office 365 will emerge to help administrators do a better job, the preview of the new Admin Center offered to create a DLP policy to protect some sensitive information that I had clearly overlooked. Well-intended as the portal was, its efforts to create the new policy failed. That’s not really important – it’s the glimpse into the future which is.
Office 365 offers different ways to apply encryption to important messages. When those messages hold sensitive data known to Office 365, like credit cards or passport numbers, we can define a transport rule or DLP policy to protect outbound email automatically. And while you can define rules and policies through the GUI, PowerShell is available too.
Microsoft thoughtfully provided Office 365 tenants with a Data Loss Prevention template for GDPR personal data. The only problem is that the rules in the template were too sensitive and started to block email.
