Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello Marko Mandli,
Thank you for reaching out in Microsoft Q&A forum.
I understand how frustrating it is when you can’t add any payment method even though all card details are correct and you’ve already tried multiple troubleshooting steps.
You’ve already tested almost everything, but these are the only additional checks that sometimes work:
- Try adding the card at this direct billing page: https://account.microsoft.com/billing/payments
- Remove all old/expired methods, then wait 30–60 minutes.
- Try adding PayPal if available in your region.
If it still cannot help:
This issue must be addressed directly with the official Microsoft Support team for Accounts and Billing:
- Go to Contact Us - Microsoft and sign in your account.
- Type Billing and payment in the search box.
- Click Get help and Select Contact Support.
- Choose Microsoft 365 and Office as Products and Services; and Billing and payment updates as Category
- Click Confirm.
- You can choose to chat with a support representative.
Note: The chat support team only works during certain working hours. Therefore, if the last window indicates that you are unavailable, try opening it again the next day. If you prefer phone support, you can leave a phone number. That way, they can call you and help you.
