Chat with live agent

To chat with a live Microsoft support agent about a billing issue and access to an invoice, use the official Microsoft Support “Get Help” flow:

1. Go to the Microsoft Support site: https://support.microsoft.com/contactus/
2. Sign in with the Microsoft account that has the Microsoft 365 subscription.
3. In the search box, type a short description such as “billing issue invoice access” and press Enter.
4. Select Get Help or Contact support when it appears.
5. Under Products & services, choose the product category that matches the Microsoft 365/Office subscription.
6. For the issue type/category, select a billing-related option such as Billing and Payment updates or Manage my subscription (wording may vary).
7. Confirm the selection, then choose Chat with a support agent in your web browser (or Chat with a support agent) when that option is offered.
8. Fill in the requested details and confirm the email address, then start the chat. The agent can review the account, help with invoice access, and advise on any billing problems.

If chat is shown as unavailable, try again during local business hours or select the Call me back option if it is offered and a phone call is preferred.
