We have three iMac computers and one macbook pro running outlook and a hosted microsoft exchange. two of the iMacs are running microsoft 360 while the other one and the laptop are using microsoft for mac 2011. We all have the same email address synced to our computers but the two with Microsoft 360 are not syncing with the other calendar and contacts. We can't see what the other add or take away. They are all syncing correctly otherwise. How can we get the calendars and contacts sync correctly?

Thanks!
