Issue with my One Drive storage space

The most likely cause is that the frozen email was sent for a different Microsoft account than the one shown in the storage screenshot.

Microsoft states that if an account appears frozen by mistake, there may be an extra Microsoft account, including one created for another service, and the fix is to sign in with the other account credentials. It also specifically advises ensuring that the sign-in is with the account that received the frozen message.

What to do:

1. Sign in to OneDrive with the exact account that received the frozen email.
2. Open Manage your OneDrive storage and verify the storage usage for that same account.
3. If that account is actually over quota, either:
   • delete files and then empty the Recycle Bin, or
   • buy more storage.
4. Wait up to two hours for storage changes to apply.
5. If the account is still frozen after four hours, contact support.

Important details from Microsoft:

• A OneDrive account can be frozen if storage is exceeded or if the account has not been signed in to for a long time.
• While over quota, existing files remain but are read-only.
• Outlook.com email can also stop working when Microsoft storage is exceeded.
• After six months, Microsoft might delete the OneDrive and the files become non-recoverable.

Since the screenshot shows 1 TB available, that screenshot does not match the email claiming a 5 GB limit. That strongly points to a different personal Microsoft account being involved.

If the email itself is suspicious, Microsoft says genuine personal OneDrive emails relate to personal OneDrive and recommends not clicking links in the email; instead, sign in directly to OneDrive to review and reactivate the account.
