I have a consultant sitting in my office, using Mac laptop and have gmail /icloud account configured on his apple mail account. He is currently sitting in my network and wants to be able to connect to our network printer and use (receive and send) his email as per normal.
When he is in my network, it seems he can't download his emails.
I have set up my exchange 2010 to allow relay to external domain but it seems not liking it either.
I go to Server configuration > Hub Transport > receive connector > create new connector. Nothing checked under authentication and permission groups.
