We are running MS-Exchange Server 2007 SP1 on Windows Server 2003 R2. Functional forest and domain is Windows 2003 native. Could someone please guide me with proper instruction on how to upgrade our Exchange Server with SP3?
Do I need to install SP2 first and then run SP3 setup? I heard that with SP3 Windows AD schema will be extended. Will SP3 setup update AD schema by itself or I have to run AD schema update first? Is anything else I have to be aware after SP3 install? Company users are using Outlook 2007 and Outlook 2010. OWA also available for remote users.
Thank in advance.
