Effective October 14, 2025, support will end for all Office 2016 and 2019 suites, standalone apps, and servers. After that date, no further updates, security fixes, or technical support will be available for these versions. We recommend starting to upgrade any unsupported versions as soon as possible.
Which products will be affected by end of support in 2025?
The following products will reach end of support on October 14, 2025:
Office suites |
|
Office applications |
|
Productivity servers
|
|
What happens when a product reaches end of support?
After a product’s support period ends, Microsoft no longer provides:
- Security fixes for vulnerabilities that are discovered and that may make devices, apps, or servers more directly exposed to security breaches.
- Bug fixes for issues that are discovered and that may impact the stability and usability of the product.
- Technical support for problems that may occur.
Continuing to use products after their end of support can negatively impact organizational security, compliance, and productivity. Because migrations can take time, we recommend starting your upgrade to supported versions of these products as soon as possible.
