About this tag
The email encryption tag on WindowsForum.com covers Microsoft's evolving approach to protecting messages and attachments through sensitivity labels and Purview policies. Recent discussion highlights Outlook for Mac gaining attachment label inheritance in September 2026, a feature already present in classic Outlook for Windows and Outlook on the web. This capability allows a sensitive attachment's label, including its encryption settings, to be applied to the composed email, closing a protection gap for Mac users. The feature is controlled by tenant policy and not enabled by default, reflecting broader enterprise IT concerns about consistent data protection across platforms. Topics here focus on Microsoft 365 roadmap items, policy configuration, and practical implications for administrators managing email security.
