Reply at all

When I hit reply all and then I reduce to icon, after the reopening I miss all the addresses to be answered. Using Windows 8.1.  Does anyone know how to help me

I’m trying to replicate your issue but am failing to do so, when i choose reply all and minimize the window, the addresses are still there when I open it.
Can you share more details about this problem or take screenshots of the separate steps?

Best regards,
