Hi @Whitney Rosenberg,
Welcome to the Microsoft Q&A forum.
I understand that you are trying to find information about a charge whose origin you have not yet been able to identify.
In this case, you can contact Microsoft’s Billing team directly for assistance in checking the details within their system.
I understand that you are an administrator of multiple tenants. You may use any tenant for which you have administrative rights to open a support ticket with Microsoft Support.
After the ticket is submitted and successfully assigned to a support agent, the agent will proactively contact you. At that point, please be prepared to provide any relevant information related to the charge, such as:
- Invoice ID
- Reference number or identifier associated with the charge
- Any other details shown on the billing transaction
Based on this information, the Billing team will assist you in reviewing and identifying the source of the charge.
Please note that, as a moderator, I can only guide you on how to reach the appropriate specialized support team. For billing‑related details, only Microsoft’s dedicated Billing team can provide official and specific information directly to you.
Steps to proceed:
Step 1: Use any account with administrative privileges and go to admin.microsoft.com
Step 2: Select Help & Support

Step 3: Enter a ticket title, for example: Contact Microsoft Billing team
Step 4: Select Contact Support > choose your preferred contact method
Notes:
- You are not required to use the exact tenant where the charge occurred.
- You may use any tenant, as long as you can provide proof of valid authorization related to the billing account. The Billing team will assist you accordingly.
- Microsoft Support operates during business hours on weekdays. If a ticket is created over the weekend, Microsoft will contact you at the beginning of the next business week.
I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this.
Thank you for your patience and your understanding. If you have any questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.
I look forward to continuing the conversation.
