OneDrive Mobile App for Microsoft 365

The OneDrive mobile app gives employees secure access to Microsoft 365 files from iOS and Android devices, including recent files, shared content, SharePoint libraries, offline files, document scanning, PDF markup, and governed sharing.

What the OneDrive mobile app does in 2026

OneDrive for work or school is the personal file workspace in Microsoft 365. The mobile app helps users open, search, share, scan, and sync files from a phone or tablet while keeping those files under your organization’s Microsoft 365 security and compliance controls. Users can access their own OneDrive files, files shared with them, Microsoft Teams files stored in SharePoint, and document libraries from SharePoint sites they have permission to use.

Find recent, shared, and relevant files faster

The current OneDrive mobile experience focuses on quick access to files you are likely to need: recently opened documents, files shared with you, starred or favorited items, and content from Microsoft 365 locations you can access. Search works across OneDrive and connected Microsoft 365 content such as SharePoint libraries, subject to user permissions. Navigation labels can vary slightly by iOS, Android, and tenant configuration, but the core experience is the same: help users find the right file without browsing through every folder.

Work with SharePoint and Teams files from mobile

OneDrive is not limited to personal work files. Because Teams channel files are stored in SharePoint, users can open and manage many Teams-related documents through the OneDrive app as well. This is useful when reviewing a proposal, accessing a project folder, or checking a document library while away from a desk. Permissions still come from Microsoft 365: users only see files and libraries they are allowed to access.

Use offline files when connectivity is limited

Users can mark selected files for offline access so they are available on a device without a network connection. This is helpful for travel, field work, site visits, and areas with unreliable connectivity. Offline files sync changes when the device reconnects, but organizations should set expectations: offline availability consumes device storage, very large files may take time to download, and conflict resolution may be required if multiple people edit the same file while disconnected. Administrators can also control mobile access with Microsoft Intune app protection policies, device compliance rules, and Conditional Access.

Scan documents and annotate PDFs

The old Office Lens branding is no longer the best way to describe this workflow. Today, users can scan documents, receipts, whiteboards, and other paper content from Microsoft mobile experiences such as OneDrive and the Microsoft 365 app, then save the result into OneDrive or SharePoint as appropriate. The OneDrive mobile app also supports viewing PDFs and using built-in annotation tools such as ink, highlights, comments, or text markup depending on platform and file type. This is useful for signed forms, travel receipts, field notes, and quick document review.

Share files securely from a phone

Mobile sharing should be convenient, but it must also be controlled. OneDrive supports sharing links with permissions such as view or edit, sharing with specific people, and—when configured by the organization—controls such as link expiration, blocking downloads for supported file types, and external sharing restrictions. Sensitivity labels, data loss prevention policies, retention, and audit logging can further protect business data. The safest default for many organizations is to encourage specific-people links instead of broad anonymous links, especially for confidential or regulated content.

Protect mobile access with Microsoft Entra ID and Intune

For business use, OneDrive mobile access should be governed through Microsoft Entra ID, multifactor authentication, Conditional Access, and Microsoft Intune. Common controls include requiring MFA, allowing access only from compliant or managed devices, applying app protection policies to prevent copy/paste into unmanaged apps, requiring app PIN or biometric access, encrypting app data, and selectively wiping corporate data when a user leaves the organization or a device is lost. These controls are especially important for bring-your-own-device scenarios.

Microsoft 365 Copilot and intelligent file discovery

Where Microsoft 365 Copilot is licensed and available, users can get AI-assisted help across Microsoft 365 content they already have permission to access. Copilot does not replace permissions, governance, or information architecture; it depends on them. Organizations planning to use Copilot should review OneDrive and SharePoint sharing practices, sensitivity labels, oversharing risks, and content lifecycle policies before rolling it out broadly.

Licensing and rollout considerations

OneDrive for work or school is included in many Microsoft 365 business and enterprise plans. If your organization purchases Microsoft cloud subscriptions through CSP, licensing is typically managed through Microsoft’s New Commerce Experience. Before rollout, confirm the right Microsoft 365 plan, storage requirements, retention requirements, external sharing policy, mobile device strategy, and user training plan. A successful deployment is not just installing the app—it is configuring secure access and teaching users how to share responsibly.

Key takeaways

• The OneDrive mobile app remains a practical way for employees to access Microsoft 365 files from iOS and Android devices.
• Users can work with OneDrive, SharePoint, and many Teams files from one mobile experience, based on their existing permissions.
• Offline access is useful, but it should be governed with storage expectations, sync guidance, and mobile security policies.
• Document scanning and PDF annotation are now part of current Microsoft mobile workflows rather than the older Office Lens-centric model.
• Secure mobile file access should use Microsoft Entra ID, MFA, Conditional Access, Microsoft Intune, sensitivity labels, DLP, and appropriate sharing controls.
