My customers would like to set up a shared address book available in their Outlook. They do not want to host their own email. They only want to have a Global Address List (i think that's what it's called) to they can use a business card scanner to scan the information into the list or add to it as needed by all employees. Dangerous enough, I know; but, that's how they want it. Is this even possible? My experience is that when you add an exchange account, let's just call it company address book, it may redirect the mailflow to that data file and everybody starts to receive everybody's email. I've had that happen.
How can I accomplish this? They want to keep the hosting with GoDaddy so they don't have to worry about an outage per say and share the address book that will be in Exchange.
One thing I did consider was putting them on Exchange anyway and setting the MX record 10 to the server and 20 to godaddy's mail server. That way, nothing is lost. But, if the server goes down, they have to go and get the mail through webmail (pain in the neck).
