I have a user with an older XP workstation and she is using Outlook 2007 as her mail client on our Exchange 2007 server. She noticed her neighbor with Outlook 2007 on a Windows 7 machine, is able to do searches and she is not. When she goes to TOOLS/INSTANT SEARCH/SEARCH OPTIONS, everything is grayed out. I did a little research and found registry hackes like; SetupCompletedSuccessfully to 0 and PreventIndexingOutlook set to 1, but she does not even have those entries. I do not even see a Windows Search service to enable or start. Is this an XP thing? Is there something I need to install on the PC to get search working?
