How to Fix Missing Microsoft Purview DLP Override Option

Sign in to the Microsoft Purview compliance portal using your administrator credentials, navigate to the left-hand menu, and select 'Data loss prevention' followed by 'Policies'.

Locate the DLP policy that is affecting the blocked emails, select it, and click 'Edit policy'.

Navigate through the policy wizard to the 'Advanced DLP rules' section and click the edit (pencil) icon next to the specific rule that is blocking the sensitive content.

Scroll down to the 'User notifications' section and ensure that 'Notify users in Office 365 services with a policy tip' is turned on. Then, check the box for 'Allow override from Microsoft 365 services' and select whether a business justification is required.

Save your changes and submit the policy. Wait for the policy to synchronize across your Microsoft 365 environment.

Sign in to the Microsoft 365 admin center using a Global Administrator account.

On the left navigation pane, click on 'Support' and then select 'New service request'.

Enter a brief description stating that the Microsoft Purview DLP override and business justification options are missing for users despite being enabled in the policy settings.

Follow the on-screen prompts to submit your ticket. You can also visit the Microsoft Purview Q&A Community to ask questions and check if other administrators are experiencing a similar service degradation.
