GCC High Priority Update
Week of July 9, 2026
Microsoft is adding screen capture blocking to the OneDrive and SharePoint web PDF viewer in Microsoft Edge, enforcing the “Do Not Allow Screen Capture” permission on sensitivity-labeled PDFs directly at the point of viewing. When a user opens a labeled PDF in the web viewer, Edge will block screenshots and screen capture attempts — preventing a straightforward workaround that has historically allowed sensitive content to leave an organization even when DLP policies were in place. For GCC High environments where document-level data protection is a compliance requirement, this update closes a gap between labeling intent and actual enforcement. The feature is currently in development and expected to begin rolling out in August 2026.

Microsoft Entra: Upcoming changes to federatedTokenValidationPolicy default settings
The federatedTokenValidationPolicy is a resource type in Microsoft Graph (beta) that governs the validation of federated authentication tokens and allows customers to configure a rule to block logins where internalDomainFederation does not match UPN domain. The feature by default requires manual configuration in the tenant to prohibit cross-domain logins. To strengthen security with cross-domain sign-in we will change the default rule for federatedTokenValidationPolicy to block logins where internalDomainFederation does not match UPN domain. This internalDomainFederation object is typically created automatically during federation setup with AD federation server or other IdPs.
