Updates available for Microsoft 365 Apps for all channels

🚨 The Signal: Microsoft 365 Apps updates are available across all channels. Organisations managing updates directly must deploy these patches to maintain security posture and address vulnerabilities.

The Impact

  • Admins: Manual deployment effort required for non-CDN managed clients.
  • End Users: Potential for disruption during update deployment.
  • Organisation: Non-compliance with security baselines if updates are not applied.

The Action

  1. Review the release notes for Current, Monthly Enterprise, and Semi-Annual Enterprise Channels to understand changes and fixes.
  2. For manually managed clients, download the latest Microsoft 365 Apps updates from the Microsoft Update Catalog or relevant deployment source.
  3. Plan and execute the deployment of these updates to all Microsoft 365 Apps clients within your environment.
