Microsoft to end OneDrive sync support on older Windows 10 releases

Microsoft will stop supporting the OneDrive sync app on older Windows 10 releases on Aug. 15, 2026, according to a notice in the company’s Message Center. The cutoff matters for IT teams still carrying pre-22H2 Windows 10 fleets: Microsoft says those clients will no longer receive updates, fixes, security patches or technical help.

The cloud storage service is not scheduled to stop working on that date. Microsoft said existing installations may keep functioning, but it did not guarantee future functionality for affected Microsoft 365 file synchronization services. That leaves organizations with a familiar enterprise software risk: a tool may continue to run, while the vendor’s obligation to repair it ends.

OneDrive sync app updates will remain available on Windows 10 22H2 until Oct. 10, 2028, Microsoft said. Earlier Windows 10 versions fall out of sync with the company’s support plan next month. Microsoft said the change “aligns OneDrive support with the Windows lifecycle policy” and allows it to focus investment on supported operating systems.

Windows 10 22H2 becomes the practical floor

The move follows Microsoft’s broader Windows lifecycle schedule. Windows 10 21H2, the last official release before 22H2, reached end of support on June 13, 2023. Microsoft’s notice also refers to Windows 10 22H1, although Microsoft did not officially ship that release after moving Windows to an annual release cadence following 21H2.

For companies, the operational impact depends on how much they rely on local file synchronization rather than browser access. Users on unsupported Windows 10 releases can still reach OneDrive through the web interface, but that is a weaker substitute for desktop sync in workflows built around File Explorer integration, local caching and background synchronization.

The least disruptive Microsoft path is to move affected machines to Windows 10 22H2, which keeps OneDrive sync support in place until 2028. A broader operating system upgrade to Windows 11 would also put users on a currently supported platform, though the notice does not attach a new OneDrive-specific deadline to Windows 11.

Alternatives remain, but with tradeoffs

The change also creates an opening for vendors selling cloud sync and file collaboration tools to organizations that do not want to move every endpoint on Microsoft’s timeline. Nextcloud told The Register that its synchronization software works on Windows 10 version 1809 and later. The company also recommends Windows 11, while offering Linux as another supported route.

Microsoft did not disclose how many users or devices remain on pre-22H2 Windows 10 releases, so the scale of the OneDrive support cutoff is unclear. The practical deadline is now set: after Aug. 15, 2026, older Windows 10 clients may still sync files, but Microsoft will not be committing engineering or support resources when they break.
