Microsoft has issued another urgent reminder to customers that **Office 2016 and Office 2019 will lose extended support on October 14, 2025** – less than 30 days away. This deadline also affects related applications including Visio 2016/2019 and Project 2016/2019.
## What This Means for Users
After October 14, 2025, these Office versions will no longer receive:
– Security updates
– Bug fixes
– Technical support from Microsoft
While the applications may continue to function, Microsoft warns that using unsupported software creates significant risks including security vulnerabilities, compliance issues, and system incompatibilities.
## Timeline of Support Changes
Office 2016 already reached mainstream support end in October 2020, while Office 2019 lost mainstream support in October 2023. Both versions have been operating under extended support, which now concludes next month.
## Upgrade Options Available
Microsoft offers several paths for organizations and individuals looking to upgrade:
**Microsoft 365 Apps**: The company’s preferred subscription-based solution that provides continuous updates and cloud integration.
**Office 2024**: A standalone release launched in October 2024, designed for small businesses and home users who prefer one-time purchases over subscriptions. It includes Word, Excel, PowerPoint, OneNote, and Outlook.
**Office LTSC 2024**: A specialized version released in September 2024 for government and commercial customers with devices requiring long-term support without internet connectivity, such as medical equipment.
## Extended Support Timeline
Both Office 2024 and Office LTSC 2024 come with extended support until **October 9, 2029**, providing four additional years of security updates and technical assistance.
## Broader Microsoft Support Changes
This Office deadline coincides with other significant Microsoft support endings. The company recently reminded users that Windows 10 support also ends in 30 days, and Exchange 2016/2019 will stop receiving security updates starting next month.
Organizations should prioritize upgrading to avoid security risks and maintain compliance with their IT infrastructure requirements.
