Urgent warning over 16 Microsoft apps: update now to avoid security risks
A critical advisory has been issued for users of Microsoft products: 16 apps under the Office umbrella and related services may leave devices exposed if they are not updated before a major software transition. Microsoft has warned that it will no longer provide security or bug fixes for older software, making timely updates essential for users who rely on Word, Excel, Outlook, PowerPoint and other familiar tools.
What’s changing and why it matters
Support for several long-standing Microsoft Office versions is ending. Office 2016 and Office 2019 will no longer receive updates after Tuesday, meaning ongoing technical support and security patches will stop. The decision affects core Office apps such as Word, Excel, Outlook and PowerPoint, as well as related programs like Access, Publisher, and Skype for Business. Without updates, these programs can become vulnerable to security threats, performance problems, and potential compliance issues for organizations and individuals alike.
Official guidance and risk implications
Jeremy Carlson, director of product marketing for Microsoft 365, warned that continuing to use software after the end of support may leave devices exposed to security threats and productivity losses. “After that date, Microsoft will no longer provide security fixes, bug fixes, or technical support for these products,” Carlson said in a Microsoft community forum. He urged users to move all remaining devices running Office 2016 or Office 2019 to a supported version as soon as possible.
Which apps are affected?
The affected suite includes the core Office applications — Word, Excel, Outlook and PowerPoint — along with Access, Publisher, and Skype for Business. While the list is centered on Office, the broader ecosystem tied to Microsoft 365 can also be impacted if devices run unsupported builds. The broader warning emphasizes a common-sense rule: update before the deadline to minimize risk to data and devices.
Security, productivity, and compliance at stake
The end of updates can open pathways for malware and phishing attempts that exploit unpatched flaws. Beyond security, unsupported software may encounter compatibility issues with newer files, services, or cloud-based features. Organizations relying on Microsoft 365 Business or Enterprise plans should plan migration steps now to ensure uninterrupted access to critical tools and services.
Recommended actions for users
- Verify which versions you are running and confirm their end-of-support date.
- Plan and execute upgrades to a currently supported Office edition or switch to a supported alternative.
- Back up important documents and test essential workflows on the updated platform before broad rollout.
- Ensure all devices, including workstations and mobile devices, receive the upgrade promptly to reduce risk.
- Coordinate with IT teams if you manage a networked environment to avoid compatibility hiccups.
What to do if you are affected
If you are unsure whether your devices or accounts are impacted, reach out to Microsoft support or your IT administrator for guidance. Microsoft’s health and status services have already flagged service degradations in related services, underscoring the urgency of upgrading prior to the deadline.
Bottom line
With an official end-of-support window in effect, the safest course is to upgrade now. By moving to a supported version of Office and related apps, users reduce security risks, minimize potential productivity losses, and stay compliant with current standards. Time is of the essence as Microsoft phases out protections for older software.
