Announcing Outlook support for DisableMandatoryInOutlook and OutlookDefaultLabel settings
Outlook clients that use built-in labeling will now support the PowerShell label policy advanced settings DisableMandatoryInOutlook and OutlookDefaultLabel.
This message is associated with Microsoft 365 Roadmap ID 72172.
When this will happen
Rollout will begin in mid-April and is expected to be complete by mid-May 2021.
How this will affect your organization
Outlook clients that use built-in labeling will now enforce 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.
This update applies to Outlook clients for desktop (16.0.14008.10000), web, iOS (4.2111+), Android (4.2111+), and Mac (16.43.1108+).
Note: Once this advanced setting update is completely rolled out, we will re-enable mandatory labeling capabilities for Outlook iOS and Android clients.
These settings will also soon be made available within the Microsoft 365 compliance center as an alternative to the PowerShell configuration. When this is available in the admin experience, you will be able to configure the settings within the Sensitivity label policy workflow. As this rolls out, reference documentation will be updated to reflect how to configure these settings in the compliance center.
What you need to do to prepare
If your organization previously turned off mandatory labeling while awaiting this feature, you can re-enable the mandatory label for Word, Excel, PowerPoint, and Outlook now.
