Cannot access my own OneDrive files, says I do not have permission.

Check and reactivate the personal Microsoft account through the Microsoft services account reset page, because the earlier lockout followed by authorization failures matches the documented personal OneDrive blocked-account recovery path.

1. Check the personal account’s status

1. Open the Microsoft services account reset page.
2. Sign in with the personal Microsoft account that owns the files, not the school account.
3. Complete any identity verification or reactivation instructions shown.
4. If verification succeeds, allow up to 24 hours for a temporary block to clear.

Microsoft documents that temporary blocks can follow suspicious activity, unusually high traffic, or sharing a large number of files. A recently verified account or one affected by high-volume sharing may be unblocked within 24 hours.^1^

Sharing files with .edu recipients is not itself documented as a problem. The potentially relevant condition is the volume or activity pattern of sharing, not the recipients’ domain.

2. Test with an isolated personal-account session

Because both personal and school identities are used in Edge, eliminate any stale or mixed authentication session:

1. In Edge, select Settings and more (…) → New InPrivate window.
2. Go directly to OneDrive.
3. Sign in only with the personal account.
4. Open My files, then try opening a file from there rather than from an old bookmark, recent-file link, school portal, or shared link.

Edge InPrivate mode supports OneDrive, provided cookies have not been blocked.^2^

If this works, remove the stale OneDrive cookies from the normal Edge session:

1. Edge → Settings and more (…) → Settings → Privacy, search, and services.
2. Select Cookies → See all cookies and site data.
3. Search for OneDrive/Microsoft sign-in entries and delete those site cookies.
4. Close Edge, reopen it, and sign in with the personal account.

Deleting site cookies signs that browser session out but does not delete OneDrive files.^3^

3. If the account specifically says “Account frozen”

A frozen account is a different state from a temporary security block. It can occur when the account remains over its storage allowance for three months or has not been used for a long time. In that case:

1. Sign in with the account that received the frozen message.
2. Open OneDrive storage management and reduce usage or purchase sufficient storage.
3. Allow up to 24 hours for the storage change to apply.
4. If the account remains frozen after 48 hours, contact Microsoft Support.

Existing files remain read-only while the account is over quota.^4^

4. Escalate with the information Microsoft needs

If My files still produces the same error in InPrivate mode after account reactivation—or on another device/network—this is no longer just an Edge-session problem. Similar reports with the exact “Unknown render failure” and “Attempted to perform an unauthorized operation” messages point to an account-specific authorization or backend failure.^5^

Because these are files in personal OneDrive, school IT generally cannot repair that account. Open or update a Microsoft personal-account support case and include:

• The Correlation ID
• Exact failure date and time, including time zone
• The personal account address, supplied privately
• Confirmation that the error occurs in Edge InPrivate
• Whether it occurs on another device or network
• The earlier lockout message and whether the reset page completed successfully
• A screenshot with personal information obscured

Microsoft directs personal-account technical issues to Contact Microsoft Support; organizational IT is the route for work or school accounts.^6^

Do not change Windows folder ownership or NTFS permissions for this symptom. Those controls apply to local File Explorer permissions, not authorization failures on the OneDrive website.
