Changelog

Outlook

Improvements for default and mandatory labeling

Sensitivity labels let you classify and protect your organization’s data, while making sure that user productivity and the ability to collaborate isn’t hindered. We’ve now improved the functionality for default and mandatory labeling in Outlook. Outlook clients that use built-in labeling will now also enforce the existing PowerShell label policy advanced settings DisableMandatoryInOutlook and OutlookDefaultLabel, previously supported only by the Azure Information Protection unified labeling client. If you have already configured these settings for your organization, they will now be enforced in Outlook clients.
