Locked Invoices

Contact Microsoft 365 business billing support by phone because the invoices cannot be paid through the normal portal flow and the online service-request route has already failed.

Contact billing support now

1. Open Microsoft’s current regional phone-number list and select your country or region: ^1^
2. Ask for Microsoft 365 for business billing support and state:
   • Two invoices show Locked.
   • The portal does not permit payment.
   • The account is restricted.
   • Online support-request creation also fails.
3. Have these details available:
   • Microsoft 365 tenant/domain name.
   • Organization name.
   • Invoice numbers and amounts.
   • Subscription or billing-account name.
   • Billing contact email and phone number.
   • A payment method authorized to settle the balance.
4. Call as a Microsoft 365 administrator. Microsoft requires an administrator for business support and might send a verification code to the email address or phone number registered in the organization profile. Billing support availability and language vary by region.^2^

If the subscriptions were purchased through a reseller or Cloud Solution Provider, contact that partner instead. Microsoft’s direct support channel requires at least one subscription purchased from Microsoft.^2^

Check whether self-service payment is still available

If you can access the Microsoft 365 admin center with a suitable billing role:

1. Go to Billing > Bills & payments.
2. Select each invoice.
3. If Pay now appears, choose an existing card or add a new card, and submit the payment.
4. For a MOSA account showing a declined payment warning, select Pay your balance, choose or replace the payment method, and complete Review and pay balance.^3^

The required permission depends on the billing-account type:

• MCA: Billing account owner/contributor, Billing profile owner/contributor, or Invoice manager.
• MOSA: At least Billing Administrator.^3^

If the invoice remains Locked and no payment action is offered, stop retrying payment methods and have billing support unlock or process the invoice.

Do not confuse an invoice lock with a billing-account lock

If Billing > Billing accounts shows the billing account itself as Locked, and it is an MCA account that was manually locked, a Billing account owner can select the account and choose Re-enable account. This returns it to Active and restores purchasing.^4^

That action does not replace payment of outstanding invoices. If the account is blocked rather than voluntarily locked, Microsoft directs customers who purchased directly from Microsoft to Support; partner and enterprise customers must contact their partner or account manager.^4^
