Jay Kothari is a Program Manager for Microsoft. He’s discussing Microsoft Office 365 system requirements and desktop setup as well as getting Macs set up.  You would need Windows XP SP3 with IE/7, Windows Vista SP2, Windows Server 2008 R2 and Windows 7. Office 2007 or Office 2010. Office 2003 will not work and of course Office 2010 is best.  The dashboard for updates will notify you for what you need for patches. WOW a DEMO, killer!  He’s showing desktop setup, Office Professional Plus, Lync 2010 and Office Desktop Apps and it just installs.  It goes out and gets information and off it goes. Sign-in Page to get to the portal, checks configuration and what tenant subscriptions are.  Looks for what the admin sets-up for instance if the admin does not select Exchange then the client side will have Outlook greyed out. This is setup per user while doing the setup or client side provisioning.  If any updates are needed during this time they will be installed locally and in a enterprise deployment senario you would use WSUS and have the updates for which components are needed. That is about it using the Desktop Tool.  Go check out http://www.microsoft.com/office365
