I'm not sure what the terminology is for what I'm looking for so I'm having a hard time finding what I need. I have an Exchange 2010 Server and Outlook 2010 for everyone in my office. I want to be able to have a contact list for all of our customers that any of us can easily update from our computers or from our phones. I have created an address list and attached it to the offline address book, but I'm not sure where to go from there. I'm not sure how to add people to the address list that I created. Is there documentation about this specific scenario? We have a mix of Android phones and iPhones that we would also like to keep updated at all times.
