I am looking for a way that I can limit access to OWA from outside my LAN. We have a number of staff who use OWA internally but who should not be using it at home. I need to find a way to restrict access to OWA from outside the LAN to a select group of employees while allowing everyone to use it internally. I had heard this can be done using the Outlook Web Access Administration tool but don't see how after trying it this afternoon. Any advice would be very much appreciated!
