I have a weird one here - I have 100+ machines running Office 2000 that work flawlessly connecting to an Exchange 2000 server. I have added three Windows XP machines to the network, 2 are running Office XP 2002 and one is running Office XP 2003. Almost 90% of the time that the Office XP machines launch Outlook they are prompted with a Server Unavailable Message, Abort, Cancel or Retry. If you click cancel and then re-launch Outlook it connects no problem. This is only happening with the Office XP machines, I have tried re-installing Office, I have even tried formatting the machine and trying from scratch with the same results. If I install Office 2000 instead of XP Outlook works as expected. ===================== Use the below link for Archives, and to set your preferences. http://thethin.net/exchangelist.cfm
