All our internal 2007 Outlook clients are receiving the 0x80190194 sync errors. I've checked the details of http://blogs.msdn.com/dgoldman/archive/2006/11/27/Error-0x80190194-when-using-an-outlook-2007-client-to-download-a-web-distribution-enabled-oab.aspx and verified that we are getting the proper 1008 events. I've seen several posts about autodiscovery settings, but I'm not sure of the settings given our situation. Any input on the following would be appreciated!!
