Hello, I'm Leonielhou, Independent Advisor and a user like you, happy to help clarify any questions you may have. I'm really sorry to hear about this.
We can try to find the Office license key using commands, ie if the key is still stored inside the PC. Here:
- On the affected computer, simultaneously press the Windows + X keys. 2. Select Windows PowerShell (Admin) or Command Prompt (Admin).
- When the window opens, type or paste: wmic path SoftwareLicensingService gets OA3xOriginalProductKey
- You can also use the command: (Get-WmiObject -query 'select * from SoftwareLicensingService'). OA3xOriginalProductKey
Both commands will display the Office license key of the computer.
Method 2: If it cannot find the license key use trial and error, you will have to manually enter all the license keys one by one until you find the correct one. Yes, it's a hassle.
However, if all else fails, I'm afraid nothing more can be done, as you said even Microsoft call support can't do anything with this issue.
