Frequently Asked Questions

Will Microsoft refund unauthorized charges?

Microsoft typically refunds unauthorized charges if they are reported promptly. However, if you cannot identify the account responsible for the charges, it is usually faster to dispute the transaction directly with your payment provider, such as PayPal.

How do I stop recurring Microsoft charges on PayPal?

You can manage and cancel automatic payments directly in your PayPal account. Go to Settings > Payments > Automatic Payments, locate the active billing agreement for Microsoft, and select 'Cancel'.

Why am I being charged for Microsoft 365 when I don't use it?

Unexpected charges can occur if a free trial automatically renewed, a family member made a purchase using your payment method, or your payment details were compromised and linked to an unfamiliar account.
