Compliance Manager is a risk assessment tool used to manage an organization's own compliance activities and score, not a repository for obtaining Microsoft's audit reports and third-party assessment documents.

The Microsoft Service Trust Portal (STP) is the official repository for third-party audit reports, compliance certifications, and assessment documents for Microsoft cloud services such as Exchange Online and SharePoint Online. It hosts SOC reports, ISO certifications, penetration test results, and other compliance artifacts that organizations can use to satisfy audit and assessment requirements. This is specifically designed to provide transparency into Microsoft's security, privacy, and compliance practices.

The Office 365 Security and Compliance Center (now Microsoft Purview) is used for managing an organization's internal compliance policies, data governance, and security configurations, not for retrieving Microsoft's external audit and certification documents.

The Azure portal is used for managing Azure infrastructure resources and services, and does not provide the audit reports and compliance assessment documents for Microsoft 365 services like Exchange Online and SharePoint Online.
