I have a computer running Windows 7 Pro that is having an issue indexing. When I have the index service set to index the Outlook 2010 mailbox and PST files, the CPU will spike to 100%, making programs and applications unresponsive and the computer will hang if a log off, shutdown or reboot is performed. This seems to only be a problem with a particular user is logged in, as when I use a different account, I don't get the hang up or freezing issue. There is an warning message in the event log for the Search source with the event id 10023 which states that the process did not respond and is being forcibly terminated. When I remove the option to stop Outlook from being index, the system runs fine. I have tried rebuilding the Outlook profile as well as rebuilding the index, neither option worked. I am not sure what my next step is other than disabling indexing of the Outlook folders which is not an option.
