How to Disable Outlook Encryption Options in Office 2021
Question details
The user needs to remove or disable the Confidential and Confidential - All Employees encryption options in Outlook.
- Product
- Microsoft Outlook 2021
- Device & OS
- not provided
- Scenario
- Managing email security settings and encryption policies in a Microsoft 365 or enterprise environment.
- Observed behavior
- Encryption options are visible in Outlook and cannot be disabled via a simple local registry setting because they are controlled by Microsoft Purview policies.
Ensure you have Microsoft 365 global administrator or compliance administrator permissions, as these settings are managed centrally through the Microsoft Purview compliance portal.
Unpublish or Modify Sensitivity Labels in Microsoft Purview
Use the Microsoft Purview compliance portal to modify the label policies that enforce these encryption options across your organization.
In modern Office 2021 and Microsoft 365 environments, message encryption is typically managed server-side. The 'Confidential' and 'Confidential - All Employees' options are provided by Microsoft Purview sensitivity labels rather than local Outlook settings.
Log in to the Microsoft Purview compliance portal using your administrator credentials.
In the left-hand navigation pane, go to Solutions, select Information protection, and then click on Labels.
Locate the 'Confidential' or 'Confidential - All Employees' label. Edit its settings to remove the encryption requirement, or choose to unpublish the label policy entirely if it is no longer needed.
Allow up to 24 hours for the policy changes to sync and apply across all Outlook clients in your organization.
Need a Lightweight Alternative for Your Documents? Try WPS Office

Frequently Asked Questions
Why can't I disable Outlook encryption via the registry in Office 2021?
In modern Office 2021 and Microsoft 365 environments, encryption options are typically deployed via Microsoft Purview sensitivity labels rather than local registry keys. This centralized approach requires server-side administrative changes to alter what options appear in the Outlook client.
How long does it take for sensitivity label changes to appear in Outlook?
After an administrator unpublishes or modifies a sensitivity label policy in the Microsoft Purview compliance portal, it can take up to 24 hours for the changes to fully synchronize and reflect in the local Outlook desktop application.
Can individual users turn off the 'Confidential - All Employees' encryption?
No, if these encryption options are enforced by a corporate Microsoft Purview policy, individual end-users cannot bypass or disable them. You must contact your IT administrator to adjust the organization's label policies.
