OneDrive app for iPhone and iPad now requires iOS or iPadOS 26 or later

As in past years, Microsoft is raising the minimum system requirements for the OneDrive app on Apple mobile devices. New versions of the OneDrive app are now only available for iPhones running iOS 26 or later and iPads running iPadOS 26 or later (starting with app version 26.1.3). Devices that are still on iOS 18 or iPadOS 18 will no longer receive new app versions and are now unsupported.

This matters for users who open, save, or share their files from OneDrive on an iPhone or iPad. The OneDrive app they already have installed is not expected to stop working right away, so their files and photo backups should remain available for now.
However, an older version of the app will not receive any new features or fixes, and over time it may work less reliably. Users on an unsupported version can still access their files by signing in to OneDrive through a web browser or using another supported device.

Users with a recent iPhone or iPad still running iOS 18 or iPadOS 18 should upgrade to the newest OS version, iOS or iPadOS 27, or alternatively to iOS or iPadOS 26 through Settings.
A few older devices can't upgrade to iOS or iPadOS 26, so users of the iPhone XR, iPhone XS, iPhone XS Max, and the 7th generation iPad won’t be able to install future versions of the OneDrive app. Users can find additional details in the compatibility list.

Users who want to keep receiving app updates are encouraged to update their devices to iOS or iPadOS 26 or later as soon as possible.
