Hello Jenny, this is Henry and I'd like to share my thoughts on your issue.
I understand the confusion, and I did some research to see what Microsoft recommends. They provide official documentation and tools to help investigate unfamiliar charges. Here are some steps you can follow:
- Even if you’ve already checked your work account, it’s a good idea to also review the order history of any personal Microsoft accounts you or family members may have. Sometimes purchases are unintentionally made from a personal account.
- Microsoft has a support page titled “How to investigate a billing charge from Microsoft” with detailed instructions. They also provide a dedicated tool to help you understand and investigate unexpected charges.
Additionally, here are some common reasons for charges you might not immediately recognize:
- Recurring subscriptions: Services like Microsoft 365 or Xbox may have renewed.
- Family purchases: A family member may have used your card.
- In-app purchases: Transactions made within apps, games, or Office products.
- Pre-orders or split orders: Items that were pre-ordered and have recently shipped.
I hope this information and these keywords help point you in the right direction for your research. Let me know how it goes, and if this answer helps, feel free to hit “Accept Answer” so others can benefit too
