Hi
Recently i migrated Exchange 2010 to exchange 2013. Still its in co-exsistence phase.
I dont want to expose my ECP site to external network. How to disable ECP access from external.
I tried IP domain and restrictions, its working by not allowing to login.. one more problem with IP domain and restrictions is in owa options(Autoreply) things and all not working...
Please suggest recommended way to disable the ECP external access.
