Microsoft fixes Teams, Outlook launch failures on ARM Windows PCs

Microsoft resolved a bug that blocked Teams and Outlook from launching on ARM-based Windows devices following updates distributed after August 2026 Patch Tuesday. The issue affected users who installed these patches on ARM-architecture systems.

Why it matters: Organizations running Teams or Outlook on ARM-based Windows PCs need to verify the fix resolves their launch failures and plan redeployment or user communication accordingly.
