I am not able to check my files/share files in onedrive,it is giving access denied

Hi,

That sounds like a permissions issue.

Is OneDrive configured in Windows File Explorer?

Add "Take ownership" to the context menu, then try taking ownership of the Onedrive folder by right-clicking.

1. Download this Registry file. https://www.elevenforum.com/attachments/add_take_ownership_with_pause_to_context_menu-reg.83409/?hash=721a3ddf88df7e0c610e519c4ab60ba6
2. Execute it and press yes.
3. Restart your PC.
4. Right-click the file or folder and select Take ownership.
5. Press yes.

See if the issue is resolved.

Keep us posted.

i dont have 365 admin

instruct me about the steps

Follow these steps to resolve the OneDrive "access denied" / "something went wrong" issue when trying to view or share files:

1. Verify that the account has permission to the OneDrive site and files:
   • In the Microsoft 365 admin or SharePoint admin environment, determine what permission level the user should have on the OneDrive site.
   • Open the OneDrive site’s Site permissions page, use Check Permissions, enter the user name, and select Check Now.
   • If no permissions or insufficient permissions are shown, grant the appropriate permissions to the site or specific files/folders.
2. If the user still gets "Access Denied" or similar errors after permissions are granted:
   • Remove the user from the OneDrive/SharePoint site.
   • Re‑add the user and share the file or folder again so that a fresh permission entry is created.
3. If the problem occurs when opening a shared link:
   • Remove the affected user from the site and then share the file or folder again so a new sharing link and permission set are created.
4. If the user cannot access their own OneDrive:
   • Check for a possible site user ID mismatch (for example, if the account was deleted and recreated with the same UPN). If a new UPN exists, delete the new UPN in Azure AD and restore the original UPN, or use the automated "Fix site user ID mismatch" solution referenced in the documentation.
5. If OneDrive or SharePoint appears completely inaccessible for the user:
   • Confirm that the user has been granted at least basic access to the site or file; if not, assign the required permissions.
   • If errors persist after permissions are confirmed, follow the same access-denied troubleshooting steps above.

If these steps do not resolve the issue, an administrator should run the "Check User Access" diagnostic (where available) or open a support request with Microsoft 365 support, providing the correlation ID shown on the error page.
