Consult the Microsoft Purview Q&A Forum for Expert Guidance

Because sensitivity label management involves strict compliance rules and specific authentication tokens, verifying the exact cmdlet sequence for your environment in the official Microsoft Purview forum is highly recommended.

Microsoft Purview and Azure Information Protection (AIP) require specific authentication flows depending on whether you are running scripts interactively or as a background service. Getting the exact prerequisites confirmed by Microsoft experts ensures you do not accidentally violate compliance policies.

Frequently Asked Questions

What is the purpose of Connect-AipService in PowerShell?

Connect-AipService is used to connect to the Azure Information Protection service to administer tenant-level settings and protection templates, rather than applying or removing labels on individual local files.

How do I remove a sensitivity label from a file using PowerShell?

Typically, administrators use the Set-AIPFileLabel cmdlet with the -RemoveLabel parameter to remove a label from a file, provided the user or service principal has the appropriate permissions to downgrade or remove the classification.

Can I run Microsoft Purview PowerShell commands without authentication?

No. Any PowerShell cmdlet that interacts with Microsoft Purview or Azure Information Protection requires authentication, either interactively or via a service principal with a token, to ensure secure access control.

Why might I get an error when trying to remove a label?

Errors often occur if the required PowerShell module (like AIPService) is not installed, if the session is not properly authenticated, or if the user lacks the specific rights required to remove or downgrade a document's sensitivity label.
