Question details

Administrators need to know how to manage custom script settings and whether specific PowerShell policies remain permanent after recent rollouts.

How to Manage Custom Script Settings in OneDrive and SharePoint

Product: Microsoft SharePoint and OneDrive
Device & OS: not provided
Scenario: Configuring tenant security policies and managing unmanaged scripts during a Microsoft rollout.
Observed behavior: Microsoft is changing how custom scripts work, creating uncertainty about whether the DelayDenyAddAndCustomizePagesEnforcement setting requires periodic renewal.

Before you start

Ensure you have Global Administrator or SharePoint Administrator privileges in Microsoft 365 to view or modify tenant-level script policies.

Solution 1Recommended

Verify Current Policy via Microsoft 365 Support

Because custom script behavior depends on Microsoft's rollout schedule and your tenant configuration, opening a service request is the most reliable way to confirm your organization's policy.

Microsoft frequently updates security policies for SharePoint and OneDrive. Contacting support ensures you receive accurate information specific to your tenant's rollout phase.

Access the Admin Center

Navigate to Support

Click on 'Support' in the left-hand navigation pane and select 'Help & support' or 'New service request'.

Submit a Request

Describe your query regarding the DelayDenyAddAndCustomizePagesEnforcement setting and ask the support team to confirm the current custom script policy for your tenant.

Tenant Specifics: Support teams have access to backend configurations that determine exactly when and how the custom script deprecation impacts your specific environment.

Solution 2

Periodically Re-enable Custom Scripts Using PowerShell

If you need to run unmanaged scripts immediately, you can re-enable the custom script setting via PowerShell, though it may require periodic renewal.
