I am afraid that there is no official way to do this. There are several tricks to intercept the window / dialog box and get the BUTTON control text. In this case, you will avoid actually static binding on the Windows resource, as shown in the link, but dynamically restore the string "as is".
But keep in mind that after you go over to compatibility issues with the Windows API, problems with 32/64 bits and so on. This is the full version.
Personally, I would implement my own "mailbox" and localize it in the selected language.
