Hi Friends, I am running exchange server 2010 and everything is working fine i am able to send and receive emails locally and outside with no issues. I am new to exchange server and learning with CBT nuggets training. OWA is working fine internally but i could not find the way how to configure it so i can access it from outside. I will be thankful if anybody can show me the ways or can give me any guidelines. Thanks very much,
