We have many area managers in our company that are on the road and collect their email using their O2 3G cards.
They collect their email directly from our exchange server using one of our fixed IP addresses as the POP server and send using smtp.o2.co.uk.
This all works fine until they come inside our network and connect with the wireless network. They obviously then want to use the direct address of our exchange server in their account settings?
Any ideas how to get around this problem? If i setup multiple accounts then one will always error on send & receive?
A solution would save me a lot of grief!
