Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Dear Jen Schripsema,
Greetings!
Thank you for posting to Microsoft Community. We are glad to assist!
Based on your description, I understand your need of a copy of Microsoft's Certificate of Insurance with all lines and amounts for coverage for your annual vendor due diligence. I have checked some information and seems there are different types of certificates of insurance based on the country you are requesting. So, it is suggested to contact our dedicated billing team so they may check which one you need and request on your behalf.
You may kindly try to contact them by generating a service request ticket to our online support through the Microsoft 365 admin center. Please believe the professional billing engineers will further help you, you can refer to Get support - Microsoft 365 admin | Microsoft Learn. Or you can directly contact your regional billing support team via phone support during business hours, See Find Microsoft 365 for business support phone numbers by country or region - Microsoft 365 admin | Microsoft Learn and Customer service phone numbers - Microsoft Support.
Note: If you are an end user, we sincerely suggest you contact your organization IT admin to create a support ticket from admin center.
Thanks in advance for your understanding! Your patience and cooperation will be highly appreciated.
