one drive wont open through my device app

Hello, thank you for reaching out to Microsoft Q&A.

1. Could you please let me know which device you’re using (Windows, Android, iOS, or Mac)?
2. Do you receive any error codes or messages when you try to launch the OneDrive app on your device?

Try the following steps based on the type of device.

If using Android (OneDrive mobile app):

1. Open Settings on the device.
2. Go to Applications > Manage Applications.
3. Find and tap OneDrive.
4. Tap Force Stop, then tap Clear data and Clear cache.
5. After that, uninstall OneDrive.
6. Reinstall OneDrive from Google Play.

If the app still cannot open files and shows a message about needing access to device storage, fix the permissions:

1. Go to Settings > Permission Manager > Files and Media.
2. Select OneDrive and choose Deny.
3. Go back to OneDrive and open a file again.
4. When prompted, select Allow or Enable permissions.

If using iOS (iPhone/iPad):

1. Uninstall the OneDrive app (press and hold the icon, tap X, confirm delete).
2. Enable Location Services on the device (recommended by Apple for background activity).
3. Perform a soft reset: hold Sleep/Wake and Home together for at least 10 seconds until the Apple logo appears.
4. Reinstall OneDrive from the App Store.
5. Make sure OneDrive is allowed to run in background: Settings > General > Background App Refresh and enable it for OneDrive.

If OneDrive still will not launch after these steps, contact Microsoft Support using the OneDrive support options.
