I have enabled OWA for all staff. They all can access owa through LAN when they are within company premises and also through Internet outside company premises.

Now I want to block some users accessing email via OWA from Internet. They should be able to access email via owa within company premises.

Please guide me.

 

i guess we can block through ISA or Firewall. Fetch the traffic from that user on ISA or Firewall and create a rules accordingly to block t

any update on this ?
