I get a huge fire alarm every month or two. Our users like to post and receive all the SharePoint lists from Outlook, but sometimes there will be mass reposts of old items, or deletion of mass items when they aren't even logged into SharePoint, or deletes a mass of discussion board entries when (again) the user isn't even in SharePoint nor deleted them from Outlook. I can't recreate the issue, and it seems completely at random. Any ideas what I can do to recreate, fix, or find out what is causing this? Its a MOSS 2007 server with Outlook 2010, and they are connected (Actions -> Connect with Outlook).
