NAT unable to reserve ports.

Do you have remote access or site-site VPN also setup and enabled on the outside interface?
If so, port 4500 is used by IPsec so I suspect it is reserved in the appliance.

yes, we have site to site vpn config on the asa!!
may be this is the reason we can't enable this port on outside interface!!

Yes. Enabling IPsec on the outside interface "siliently" reserved that port.
