This may have been asked before but i will give it a try. I have a customer that is currently running Server 2008R2 as a DC ie: mycompany.local. They use outlook 2010 to connect to their ISP for POP3 email accounts ie: email@example.com.
They would like to use Exchange to share calendars. I have seen it setup in the past with exchange that the users have both a pop account and an exchange account in their mail client.
Is there a way that i could setup exchange so that they only use the pop accounts but still have the ability to share the calendars? If so, what would be the safest procedure to do so without causing open relays and such.
Thanks for your time in advance!
