Encrypted email is becoming more common within Office 365. Things usually flow smoothly when sending protected messages to email recipients, but other Office 365 recipient types like Teams and Yammer might not be able to handle protected email.
Making it easy to protect Office 365 content with encryption is great, but it has some downsides too. One of the obvious problems that we have is that encrypted documents in SharePoint and OneDrive for Business libraries can’t be found unless their metadata holds the search phrase.
The Office 365 Security and Compliance Center includes a report to detail encrypted email. The report is in preview. It’s a nice insight into user activity, even if it has some glitches that need to be sorted out before it becomes generally available.
Rights management and encryption are likely to be a much more common Office 365 feature in the future. Sensitivity labels makes protection easy for users to apply through Office apps. The downside is that protection makes content harder to access for some Office 365 and ISV functionality.
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.
