How to Fix 'Cannot Open PDF Files' When OneDrive Requests Storage Access on Your Phone

Product: OneDrive
Device & OS: not provided
Scenario: Attempting to open a locally downloaded PDF file on a mobile device.
Observed behavior: The phone blocks the PDF from opening and displays a prompt requesting OneDrive storage permission, indicating OneDrive is set as the default PDF handler but lacks the rights to read local files.

Before you start

Verify that the PDF file is completely downloaded to your local device storage and is not corrupted before attempting to change application permissions.

Solution 1Recommended

Grant Storage Permissions to the OneDrive App

Resolve the prompt by allowing OneDrive the necessary permissions to access and open files on your device storage.

If OneDrive is your preferred PDF viewer, the quickest way to fix this issue is by simply granting the app the permissions it needs to read files from your device's internal storage.

Open Device Settings

Navigate to your phone's main Settings app from the home screen or the app drawer.

Locate App Settings

Tap on 'Apps' or 'Apps & notifications' to view the complete list of installed applications on your device.

Select OneDrive

Scroll through the application list or use the search bar to find and tap on 'OneDrive'.

Enable Permissions

Tap on 'Permissions', select 'Storage' (or 'Files and media'), and choose 'Allow access'. Try opening your downloaded PDF file again.

Frequently Asked Questions

Why is OneDrive trying to open my downloaded PDFs?

OneDrive includes a built-in PDF viewer. If you previously opened a PDF and selected 'Always' for OneDrive, your phone sets it as the default application for all future PDF files, even those stored locally.

How do I stop OneDrive from asking for storage permissions?

You can either grant the requested storage permissions in your phone's Settings > Apps > OneDrive > Permissions, or clear OneDrive as the default PDF app so another dedicated application handles your documents.

Can I open PDFs on my phone without a cloud storage app?

Yes, you can install a dedicated, offline PDF reader like WPS Office. Once installed, simply clear your previous defaults and select the new app when opening a PDF to avoid cloud-related permission prompts.
