I would expect that they exist until CloseMsgQueue() is called for all handles returned by CreateMsgQueue() using the same name.

Then there is no need to check if a queue is alive because it is under control of the application. The application can simply clear the handle variable after closing the queue to indicate that the queue does not exist anymore.

It is more important to close message queues when no longer used because they are system resources which are limited. That means: When not closed, they will exist until rebooting the system.
