Outlook 2007 integration with SharePoint 2010

From SharePoint 2010 document library you can select 'Connect to Outlook' to sync with outlook. SharePoint 2010 and Outlook 2010 both use the Ribbon - the standard UI used across the Microsoft Office Products.
Once you synchrnoize a document library from SharePoint it appears as a folder in the Outlook navigation Pane under SharePoint Lists. You can edit the documents off-line in outlook and synchronize back to SharePoint.
Synchronized content in Outlook is kept only in read only mode and so cannot be deleted from SharePoint by deleting from the local copy. You can synchronize SharePoint Task List.
But Out of the box SharePoint Lists cannot be viewed from Outlook. The option 'Connect to Outlook' is not selectable and appear in grey for OOTB SharePoint Lists. RSS feeds,Contacts and Calendars can be synchornized between SharePoint and Outlook.
