The Edit in Datasheet View is not available on a List or you cannot see "Connect to Outlook" on a list

The data grid view itself comes from web components provided with Microsoft Office. This can be problematic in organizations with customized installations of Office, as they often don’t include the Windows SharePoint Services Support feature. If you can’t edit a list in grid view, go to Add/Remove Programs, change the Office installation, locate the Office Tools category and select Windows SharePoint Services Support.
