Data at rest encryption for Microsoft 365 provides Customer Key based encryption across multiple Microsoft 365 workloads. Tenant administrators can configure a single data encryption policy using customer managed keys and assign it to the tenant. Once assigned, the tenant-level encryption policy starts encrypting all customer data for multiple M365 workloads. This policy doesn’t interfere with any finely tuned data encryption policies already assigned using Customer Key for Exchange Online and SharePoint Online.
