Hello Microsoft Support Team,

I am experiencing an access issue with my personal OneDrive account, which is currently using approximately 77% of its storage capacity.

I am unable to access my files because they were originally created and synchronized using a corporate Microsoft account. I believe there may be a conflict between my previous corporate account and my current personal Microsoft account [--PII REMOVED--].

When I try to access my OneDrive files or submit a support request, I receive the following errors:

  • Error: UnauthorizedAccessException

HRESULT: 0x80070005 (E_ACCESSDENIED)

HTTP Status: 403 — Access Denied

Error Code: 917656

Message: "Access is denied. Before opening files in this location, visit the site and select the option to sign in automatically."

I also receive the following message:

"You don't have permission to access this item."

I suspect that my files may still be associated with the previous corporate account, preventing my personal account from accessing them.

I would appreciate assistance from a Microsoft support technician to:

Identify the cause of the authorization and access issues.

Verify whether my files are still associated with the previous corporate account.

Help restore access to my OneDrive files using my personal Microsoft account.

Confirm whether there is an account association or authentication conflict.

Ensure that my files remain safe and are not lost during the troubleshooting process.

I can provide screenshots, error details, and correlation IDs if needed.

Thank you for your assistance.

Best regards,

    Hello Ailson Lemos Costa,

    Please note that our Microsoft Q&A forum is a public platform, and we will modify your response/ question to hide your personal information in the description. Kindly ensure that you hide any personal or organizational information the next time you post an error or other details to protect personal data.

    Thank you for providing the detailed information.

    Based on your description, the issue may be related to the files still being associated with a previous corporate Microsoft account rather than your current personal Microsoft account. The 403 Access Denied, UnauthorizedAccessException, and 0x80070005 (E_ACCESSDENIED) errors can occur when the account currently signed in does not have permission to access the OneDrive content.

    To help narrow down the cause, could you please clarify the following:

    1. Were the files originally stored in a personal OneDrive account or in your organization's OneDrive for Business account?
    2. Does the issue occur when accessing OneDrive through a web browser as well as through the OneDrive desktop application?
    3. Do you still have access to the previous corporate account, or has it been removed/deactivated by the organization?
    4. Are you able to see the files listed in OneDrive, or do you receive the access-denied error before any files are displayed?

    Additionally, please let us know whether the issue occurs across multiple devices and browsers.

    Based on your answers, we can help determine whether this is an account ownership issue, a permission issue, or a problem related to cached credentials from the previous work account.

    I look forward to your update.
