Support Termination Alert for Microsoft Office 2016 and 2019
Microsoft has officially announced that its Office 2016 and Office 2019 suites will lose extended support on October 14, 2025. This critical timeline is just six months away, meaning significant changes for users of these versions.
Understanding Support Lifecycles
Office 2019 had already transitioned out of mainstream support in October 2023, mirroring a similar move for Office 2016 back in October 2020. This upcoming deadline marks the end of all updates, security patches, and technical support for these products.
Implications of Using Outdated Software
Continuing to utilize software that’s no longer supported can expose users to numerous risks:
- Security Vulnerabilities: Without ongoing updates, these apps become prime targets for cyber-attacks.
- Compliance Issues: Regulatory practices might require up-to-date systems, putting outdated software at risk of non-compliance.
- System Incompatibilities: New hardware and software may not function optimally with outdated Office versions.
Additional Products Facing End of Support
It’s not only Office 2016 and 2019 that are impacted. Microsoft has noted that Visio 2016 and 2019, as well as Microsoft Project 2016 and 2019, among others, are also scheduled for end of support on the same day.
Recommended Upgrade Paths
Microsoft strongly recommends upgrading to Microsoft 365 or Office 365 suites as soon as possible to mitigate any risks associated with outdated software.
- Microsoft 365 Apps: Offers continuously updated versions of classic applications such as Word, Excel, and PowerPoint available across desktop, mobile, and web platforms.
- Guidance for Upgrades: Detailed instructions on how to transition from older Office versions to Microsoft 365 Apps are available on Microsoft’s support website.
Alternative Solutions: Office 2024 and Office LTSC 2024
For users looking for non-subscription alternatives:
- Office 2024: Launched for small businesses and consumers in October 2024, this standalone version provides the familiar Office suite without a Microsoft 365 subscription.
- Office LTSC 2024: Released in September 2024, this volume-licensed, perpetual version is tailored for commercial and government entities requiring long-term, non-internet-connected solutions.
Both Office 2024 and Office LTSC 2024 are set to receive support until October 9, 2029, ensuring four additional years of product security and reliability.
Attention IT Admins
It’s crucial to also note that Exchange 2016 and Exchange 2019 are approaching their support end-date concurrently on October 14, 2025. Transition plans to Microsoft 365 or Exchange Online should be prioritized to ensure seamless migration and continuous operational efficiency.
