We are having some issues with our outlook. Most clients we had to take off cashe mode so they could see new email but in doing so they can no longer see the Global contact list. If we turn on cashe mode they can see the Global contact list but unable to see any new Emails. We moved our server from one san to the another San and had to take the server down to move it but that was all that happened. When the server came up the ISS services had to be started. The server is a newer Exchange server 2010 with Windows 8 on the box and is virtual.
