How to "Unarchive"?

Greetings,
I have mistaken the "Archive" task as a process of moving mail from one folder to an "Archive Folder". However, "Archive" is not a folder, it is more of a sub-folder within folders.
Now that I know this, I no longer need to have this email archived within the folder it is in, I need it moved out of the archive and into a different folder.

Problem:
I cannot seem to move this archived mail to another folder. I cannot seem to delete the archived mail, nor can I "Unarchive" the archived mail.
I also had difficulty finding the message after I had archived it.

Is this how it is meant to be?
