Hi Rudhin Menon,

Thanks for reaching out to Microsoft!

405 Error indicates that the HTTP method in the request isn't allowed on the resource.

As mentioned in the document, if you are using personal Microsoft account then the account must be tied to a Microsoft Entra tenant to update your profile with the User.ReadWrite delegated permission on a personal Microsoft account.

Also test the API in postman application by using your personal Microsoft account credentials.

Hope this helps.
