Blocking downloads on unmanaged devices

Employees signing in on a home PC or a hotel computer can easily download company files. With the unmanaged devices setting in SharePoint, those devices only get limited, web-only access: view and edit online, but no downloading, printing or syncing. This article shows how.

What is an unmanaged device?

A device that isn't Entra joined or hybrid joined, and isn't marked compliant in Intune. For example a personal laptop or a shared computer.

Set limited access

  1. Go to the SharePoint admin center > Policies > Access control > Unmanaged devices.
  2. Choose Allow limited, web-only access, or Block access.
  3. Select Save.

SharePoint automatically creates two Conditional Access policies in Entra ID. Check them there, and exclude your break-glass accounts.

Setting unmanaged devices in the SharePoint admin center

What does the user see?

On an unmanaged device the user sees a banner: Your organization doesn't allow you to download, print, or sync from this device. Opening files in Word, Excel and PowerPoint for the web still works. It applies to Teams files and OneDrive too.

Limited access on an unmanaged device

Only for certain sites

Only want this for sensitive sites such as HR or Finance? Keep the organisation setting on Full access and set it per site with PowerShell:

Set-SPOSite -Identity https://contoso.sharepoint.com/sites/hr -ConditionalAccessPolicy AllowLimitedAccess

Or use a sensitivity label that enforces the restriction.

Licence

You need Entra ID P1 for Conditional Access, for example through Microsoft 365 Business Premium or E3. Read what Entra ID P1 gives you.
