Unknown preauthorizing charges in addition to subscription invoices without any clear evidence-

Hello Rohit, thank you for posting your query on Microsoft Q&A platform.

To better understand and assist with the unexpected charges, could you please confirm the following:

• Is this the Azure subscription in question?
• Could you share a screenshot or details of the unknown charges (invoice line items or billing scope)?
• Are these charges visible under Cost Management (Azure) or Microsoft 365 admin center, or both?
• Have there been any recent changes such as new subscriptions, resource deployments, or license assignments?

Thanks.

Please check ab

Please check above, to answer your question, there is no matching transaction in Microsoft Cost Management. We have office 365 plan that we get billed separately as well and the only external resource we have is Pinecone but that's on $50 plan. I hope it helps.

When reviewing your bank/credit card statement, it’s important to differentiate between temporary authorization holds and actual billed charges:

Pre‑authorization (temporary hold)

• Appears as "pending" or "authorization" on your bank statement
• Does NOT appear in Azure invoices
• Automatically released/reversed by Microsoft after verification
• Triggered by:
  • Billing thresholds
  • Payment method validation
• These are not deducted permanently, even though they may temporarily reduce your available credit

Microsoft confirms that such authorizations are reversed after approval and don’t result in a settled transaction.

You can confirm whether a charge is real or just a hold, you can verify it using the portal:

1. In Azure Portal > Go to Cost Management + Billing
2. Select your Billing profile
3. Navigate to:
   • Invoices > Download and review the invoice PDF
   • Cost analysis > Check usage and charges by service
4. Compare:
   • Invoice total vs your card statement
   • Individual invoice line items (services, meters, usage)

Only items listed in invoices represent actual billed amounts.
