Wait a minute. I think I read one post that asked you to remove all forwarding. Did you do that? If you do, what happens when a call from the outside is directed to that extension?
With the forwarding removed, if an outside call is completed to another working extension and that call is transferred to this problem extension, what happens?
When you write that the outside caller goes to the company's main greeting, is the greeting coming from the system voice mail automated attendant feature or is it coming from another piece of equipment being used for auto attendant?
There are a lot of variables here that need to be nailed down. I am convinced it's not a switch issue. When you deleted the extension, you wiped out every condition that could have existed that would make the problem you described. Check out all the "boxes" and provide a list of everything that is associated with the telephone system. With all the pieces in place and known, this is an easy problem to correct.
