Starting August 26, 2026, Microsoft Viva Glint's Copilot features will be unavailable to Microsoft Entra cross-tenant guest users due to underlying service limitations. Affected users will no longer see Copilot functionalities, but other Viva Glint features remain unchanged. No admin action or Copilot license assignment will restore access.
