Earlier this month the AIP team released Sensitivity labels for Word, PowerPoint & Excel and Sensitivity labels GA for Outlook Web (Office 365). But it seems they have more! Which makes sense because we are missing Outlook on Windows support.
It’s not entirely a surprise, the Microsoft 365 Roadmap already indicated “Rolling out” for feature ID 44922.
Sensitivity labels for Office ProPlus is currently available in Monthly Channel (Targeted), it looks to be version 1910 (build 12130.20272) and up
Next to support in Outlook, the Sensitivity labels are also supported in Office ProPlus for Word, Excel and PowerPoint.
