This policy setting allows you to deploy SharePoint lists. If you enable this policy setting, you can provide a list of SharePoint list URLs in the following format: Value name: SPsite1 Value: SPsite1 stssync:// URL. See MS-STSSYN for documentation. Value name: SPSite2 Value: SPsite2 stssync:// URL. See MS-STSSYN for documentation. The list of URLs provided is read when Outlook starts up, and the corresponding SharePoint lists are added to each of the user's profiles. If you disable or do not configure this policy setting, users will not have any default SharePoint lists.
