OK, I understand what you're saying. And it is an interesting observation, which I didn't take into account so far. On the other hand, I observed this behavior also with other executables. In fact, my actual problem is related to another (specific) program, and I used the msg.exe really just to have something simple to demonstrate the issue in a post in this forum. In particular, I noticed that double quotes characters inside one of the passed arguments can destroy the whole execution. Which makes me think, that there is "something" interpreting the arguments, instead of purely passing the argument string "as is" to the executable, at the desired argument position. Anyway, thanks for your feedback!
