OneDrive app for iOS fails to upload files through the File Provider Extension and Sharesheet

SN_01 81

Files Provider Extension bug in OneDrive app for iOS: OneDrive app for iOS fails to upload files through the File Provider Extension and Sharesheet from inside any app (like Photos or Mail or Whatsapp) on iOS device.

The issue is failure of file upload from OneDrive app using Files Provider Extension through iOS Files app. I have tried to upload the file with another OneDrive account, but it fails in the same way and the problem remains the same. This confirms that the issue is with the Files Provider Extension usage of OneDrive app and not with the OneDrive account.

The issue is not restricted with PDFs and photos, but occurs with all type of files. It occurs with all type of files like .docx, .xlsx, .pdf, .zip files, etc.

This issue occurs from all apps when files are uploaded using Files Provider extension through iOS ShareSheet. It occurs when trying to uploading file from any app via the Sharesheet option (e.g., from iMessage, Photos, or Mail, Whatsapp).

The issue occurs even when uploading is tried from different locations within the iOS Files app (e.g., local storage). The issue is occurring while trying to upload with a normal folder (folder is not a shared folder). I am not using any VPN connection, but am directly connected to internet.

All the trouble shooting steps, viz. Clear Cache in iOS, Clear OneDrive Account Settings, Offloading the OneDrive app, Re-installing OneDrive app, have been tried multiple times on different iPhones.

Yet the problem remains the same on all iPhones. The issue occurs even after trying file upload from different networks and on all iPhones.

The upload happens without any problem when tried through OneDrive web.

There is also no problem when trying to upload through Files app to other cloud service providers like Google Drive account, or Dropbox account, or iCloud.

The problem is only when Files are tried to be uploaded on OneDrive account through Files app.

I have an similar issue:

iOS Files App Integration Error: SharePoint Uploads Stuck with "01/01/1" Date (Recent Regression)

Hi everyone,

I am experiencing a persistent and frustrating issue when trying to save PDF files directly from a web browser to a SharePoint/OneDrive location using the native iOS "Save to Files" integration.

The Problem:

This feature used to work perfectly fine until just a few weeks ago. Without any changes to my device settings, it has suddenly stopped working. Now, when I try to save a file, it appears in the destination folder within the Files app but never actually uploads. It shows a cloud icon with an exclamation mark, and the file metadata displays a placeholder date of 01/01/1 (a null/Unix zero date).

I am doing a lot of work from my mobile devices and am trying to avoid the "double work" of saving files locally and then manually uploading them via the OneDrive app. I need the direct integration to function as it did previously.

System Info:

• Devices: iPhone and iPad (Both experiencing the same issue).

• OS Version: Both devices are fully up to date.

• App Version: OneDrive and SharePoint apps are fully up to date.

• Context: No setting changes were made; this appears to be a regression caused by a recent iOS or Microsoft app update.

Troubleshooting Already Attempted (I have tried all 12 of these steps with no success):

Account Re-authentication: Signed out and back into the OneDrive/SharePoint apps.

Connection Check: Switched between WiFi and Cellular; disabled all VPNs.

File Naming: Renamed PDFs to simple names (e.g., test.pdf) to rule out special characters.

App Offloading: Offloaded the OneDrive app via iOS Settings to refresh system files.

File Provider Toggle: Toggled the OneDrive/SharePoint provider OFF and ON within the Files app "Browse" menu.

Background App Refresh: Confirmed it is ON for both Files and OneDrive apps.

Upload Queue Clearance: Manually checked and cleared the "Uploads" section within the OneDrive app.

SharePoint Shortcut Method: Used "Add Shortcut to My Files" in OneDrive to simplify the SharePoint path.

Compliance Check: Verified no "MAM" or "Intune" blocks in Microsoft Authenticator/Company Portal.

The "Nuclear" Reset: Deleted apps, Force Restarted the device, reinstalled, and toggled "Reset App" in Settings.

Direct Share Sheet Bypass: Tried "Open in OneDrive" (the app icon) instead of "Save to Files" (the folder icon).

Automation/Shortcuts: Attempted to use the iOS "Shortcuts" app to automate the upload directly to the path.

Despite these 12 steps, the "File Provider" extension continues to fail. Given that this worked a few weeks ago, it feels like a bug in the recent versioning. Has anyone else encountered this sudden "01/01/1" error?

Hi, SN_01

From what you described, this really sounds like an issue in OneDrive’s iOS Files/Share Sheet integration, not your account. Since it fails across different iPhones, networks, file types, and even other OneDrive accounts, the problem looks isolated to the OneDrive extension path. It is suggested that you check whether Background App Refresh and Location Services are enabled for OneDrive, and if photos are involved, turn off iCloud Optimize iPhone Storage. It is also recommended that you toggle OneDrive off and back on inside the iOS Files integration, because that can refresh the broken link. If upload works only inside the OneDrive app itself, that is probably the safest temporary workaround until Microsoft release future updates.

Thank you for your patience in reading, I hope this information has been helpful to you.

In my view its an issue with the OneDrive app on iOS. The app itself works, but not its integration within other iOS apps (like Files, or LiquidText). I am still experiencing it, and it only started happening after the most recent OneDrive app update (which is why I suggest its a OneDrive app issue)

We're experiencing the same issue. We are developing an app where we need to load pdfs and some of our users are using OneDrive.

Is there a bug ticket or something like this which we can follow so that we are informed when it is fixed?

Kai-H - how do I "toggle OneDrive off and back on inside the iOS Files integration"?

Hi, Sam Wilson

What I meant by “toggle OneDrive off and back on” is the Files app integration switch in iOS. It is not inside the OneDrive app itself.

On the iPhone or iPad:

Open the Files app.

Tap Browse.

Tap the three dots (⋯) in the top right.

Tap Edit.

You will see OneDrive listed under Locations.

Turn OneDrive OFF, tap Done, then fully close the Files app.

Restart the device.

Open Files again, go back to Browse > ⋯ > Edit, and turn OneDrive ON.

This forces iOS to rebuild the OneDrive File Provider link, which sometimes clears a stuck or broken integration after a OneDrive app update.
