Runnng into an issue with a hosted exchange email service whereby all the Outllok 2007 and 2010 clients report "This folder is up to date" instead of "all folders up to date". Outlook 2003 reports "all folders up to date. I suspect this issue is related to autodiscover as there were a few issues we went through. The following autodiscover related features are working however in 2007 and 2007: Out of Office assistant, Offline Address book, Busy Calendar status. All the 2007 and 2010 Outlook clients in the corporate office have this issue and the ones outside the office don't so I suspect a DNS or firewall issue is the culprit. Any ideas on what the required conduit is for the all folders are up to date status?
