Microsoft Payments MSFT . [Moderator note: personal info removed]

Good day @Marco van der Weide, thank you for taking the time to post your question and for describing your situation in such clear detail.

First, I’d like to gently clarify that invoices and billing documents are considered confidential records between you and Microsoft once a transaction has occurred. Because of this, neither community members nor moderators (including myself) have the ability to access, retrieve, or send invoices.

Under normal circumstances, invoices can be viewed and downloaded directly from the Microsoft 365 Admin Center by signing in with an administrator account and navigating to the Billing section, specifically the Bills & payments page. This aligns exactly with what you mentioned in your post.

However, in your case, the administrator account ending with onmicrosoft.com is currently inaccessible because the Microsoft Authenticator app is no longer linked, which unfortunately blocks the sign‑in process.

Because of that, the first and most important step is to regain access to that administrator account. Once access is restored, you should be able to sign in normally and retrieve the invoice without any further issues. Since your recovery email address has already expired, the recommended path forward is to contact Microsoft Support directly by phone: Customer service phone numbers - Microsoft Support and request assistance from the Microsoft Data Protection team. This team specializes in account recovery scenarios like yours and has the necessary tools and verification processes to help restore access securely.

Here are some tips and an example of a prompt to help you navigate the IVR more effectively: 

(When you call the support number, you may hear an introduction of about 30 seconds such as "you can visit the link...". You can ignore this introduction and wait until you are presented with the options. Then press "1" as a business email user, and again "1" for technical help.)   

In some regions, the initial interaction may be automated, so here’s a general idea of how the conversation might go to help you prepare:     

• What kind of problem are you experiencing?        
• Answer: Authenticator        
• What products do you use?        
• Answer: Office 365 for business        
• Is this for an education or company account?        
• Answer: For companies        
• Are you an administrator?        
• Answer: Yes        
• Are there any other administrators in your organization?        
• Answer: No. I am the only admin in my tenant         
• Do you need a... Service request?         
• Answer: Yes. I need to create a ticket. Please send me direct to the Data Protection Teams.     

During the phone call, you will need to provide the information associated with your subscription, such as your company name, billing details, phone number, and an alternate email address, etc. This information allows the Data Protection team to verify your identity and securely assist you in regaining access to your administrator account.    

Once that process is completed and you regain access to the admin account, you’ll be able to log in to the Admin Center and download the invoice you need.

If you have any updates or if anything is unclear in my response, please feel free to leave a comment directly under this post. Doing so makes it easier for me to stay notified and continue supporting you here in the discussion. While I’m limited by my role and can’t directly intervene with account access or billing data, explaining the process clearly and guiding you to the right specialized support is the most effective help I can offer from my position.

Thank you again for your patience, and I sincerely hope you’re able to recover access and obtain the required documents very soon.
