I have a SharePoint Task List connected to Outtlook 2007 from the OfficeLive Small Business website. Now and then the information on the site is updated but the changes are not passed down to Outlook 2007 (even after a send/receive). Strangly a quick restart of Outllok will cause the List to update.
So it clearly isn't the SharePoint site rextricting the frequency of the updates. Is it possible that Outlook 2007 will only update connections at a mximum frequency?
