OneDrive for Business, mounted as a drive.
Mount OneDrive for Business and Microsoft 365 OneDrive as a native drive on macOS, Windows, and Linux. Microsoft Graph API, tenant SSO, Conditional Access compliant — and the only real Linux OneDrive Business client.
— What you get
Tenant OneDrive, the way desktop access should work.
Mounted in Finder and Explorer.
Your OneDrive for Business appears as a native volume. Open files in Office, Adobe, IDEs, anywhere — and save back directly. No upload step, no manual sync state.
Stream on demand.
No full local mirror of your tenant's OneDrive. Files stream when opened, cache locally for fast re-open, and stay in the cloud the rest of the time. Pin folders for guaranteed offline access.
Tenant SSO + Conditional Access.
Authentication runs through Microsoft Entra ID (formerly Azure AD). Your tenant's MFA, Conditional Access, device-compliance, and sign-in risk policies all apply — ExpanDrive is governed by exactly the same trust envelope as the official OneDrive client.
Linux, finally.
Microsoft has no native Linux OneDrive client — for Personal or Business. ExpanDrive ships native .deb and .rpm packages and is the only commercial OneDrive for Business client on Linux.
— Cross-platform
OneDrive for Business on every OS.
macOS
Apple File Provider extension. Tenant OneDrive appears in Finder and ~/Library/CloudStorage. Apple Silicon native.
Windows
User-selectable drive letter per tenant. Signed MSI installer for Intune / SCCM / GPO deployment.
Linux
Native .deb / .rpm packages with signed apt and yum repositories. The only real Linux OneDrive for Business client — Microsoft ships nothing here.
— vs the OneDrive Business client
Where the official client falls short.
Microsoft's OneDrive for Business client is solid on Windows and Mac. ExpanDrive fills three real gaps — the Linux gap, the multi-tenant gap, and the sync-vs-stream gap.
- No Linux client at all. Microsoft ships OneDrive for Business on Windows and Mac only. Linux is unsupported — no first-party client, no community fork, no roadmap. ExpanDrive runs on Ubuntu, Debian, Fedora, RHEL, CentOS.
- Single-tenant by default. The official client makes multi-tenant access awkward — you can sign into multiple accounts, but each adds configuration overhead. ExpanDrive mounts every tenant you have access to as its own labeled drive simultaneously.
- Sync-vs-stream is binary. Files On-Demand exists, but it's tenant-policy-controlled and the toggle doesn't always behave the way you'd expect. ExpanDrive streams by default and lets you pin folders for offline — both modes, always available.
- Personal and Business are separate clients. The Microsoft world treats personal OneDrive and OneDrive for Business as different products with different installers and different sync engines. ExpanDrive mounts both as drives through the same app.
— Microsoft 365 family
Mount the whole Microsoft 365 surface.
OneDrive for Business is the personal layer of Microsoft 365 storage. SharePoint is the shared layer. ExpanDrive mounts both — and personal OneDrive for the cross-tenant case.
