Over storage problem

This is not an actual storage overuse problem, but a known provisioning / synchronization issue that can occur with Microsoft 365 Family accounts after a subscription lapses and is later renewed.

Your screenshots clearly show a contradiction:

• The banner says:
  “You’re over your storage limit (3562%)”
  → this corresponds to the 5 GB free tier
• The storage management page shows:
  178.1 GB used out of 1 TB (17%)
• The account is listed under an active Microsoft 365 Family subscription (1,024 GB)

Conclusion:
The family member account does have 1 TB assigned, but one or more Microsoft services (OneDrive / Photos / Outlook backend) are still treating the account as a Free (5 GB) account.

Why this happens

This typically occurs when:

• A Microsoft 365 Family subscription expires
• The account temporarily falls back to the Free 5 GB quota
• The subscription is later renewed
• One or more family member accounts fail to re-provision correctly

As a result:

• OneDrive web may show the correct quota
• Uploads, Photos, or email attachments are blocked
• The “over storage” warning persists indefinitely

Waiting does not reliably fix this.

What does NOT fix the issue

The following actions are usually ineffective:

• Signing out and back in
• Clearing browser cache
• Deleting files
• Clicking “Manage storage”
• Waiting for automatic sync

The quota is wrong server-side, not client-side.

Recommended solution (most reliable)

Remove and re-add the family member

This forces Microsoft to re-provision the storage correctly.

 1. Sign in as the Family Organizer
https://account.microsoft.com/family

 2, Remove the affected family member completely
(Do not just change storage — remove them from the family)

 3. Wait 10–15 minutes
This is important to allow backend cleanup.

 4. Re-invite the family member

• Have them accept the invitation
• Confirm that 1 TB storage is assigned

 5. On the affected account:

• Sign out and back in
• Open https://onedrive.live.com
• Check storage status

In most cases, the “over storage limit” banner disappears shortly after this.
