Hello Péter Palácsik
I can see that you have already tried the AI suggestion, but it was ineffective in solving this issue.
Since the board is missing from the gallery, you are signed in with the original personal Microsoft account, and no direct board link is available, there are no further recovery checks that can be performed through the Whiteboard interface.
Microsoft Q&A is a public community forum, so contributors and moderators cannot access Azure-backed Whiteboard storage or escalate the case internally.
Please contact Microsoft Support directly for further assistance:
Please note that this is a user-to-user support forum. Moderators and contributors, including external Microsoft employees, are not allowed to directly interfere with Microsoft product features or access back-end systems. Our role is limited solely to providing technical guidance on reported incidents, requests, or ideas.
- Open a website link - Contact - Microsoft Support
- In the box below "We're here to help", type Microsoft 365, click "Get Help", and then click "Contact Support" below.
- In this section, you will need to sign in to your Microsoft account.
- Select "Microsoft 365 and Office" under Products & Services, select "Technical Support" as the category, and click to confirm
- You can select " Chat with a support agent in your web browser " to access the chat window.
When contacting support please include the approximate date the board was created or last accessed, its title if remembered, and the devices or Whiteboard clients previously used.
Please note that server-side recovery cannot be guaranteed, but Microsoft Support is the appropriate channel to determine whether any investigation or recovery option is available.
I hope you can get the support you need,
have a nice day.
