About this tag
The microsoft 365 apps tag covers patch management, update channels, and lifecycle planning for Microsoft's Office suite. Recent discussions focus on August 2026 security updates for PowerPoint vulnerabilities CVE-2026-70316 and CVE-2026-70313, emphasizing that Office fixes require separate deployment from Windows updates. Administrators are also navigating the July 2026 channel unification, which moves devices from Semi-Annual Enterprise to Monthly Enterprise Channel starting with Version 2606. The tag includes guidance on Office LTSC 2021 end of support on October 13, 2026, with migration paths to Microsoft 365 Apps or Office LTSC 2024, and notes that Microsoft 365 Apps support on Windows Server 2022 ends the same date, affecting RDS and VDI environments.
