Vista x32 box with Outlook 2007. Outlook is not running. Hasn't been fired up for several reboots. I stopped WMI service and Windows Search service. Machine is mostly quiet, and then servicehost.exe launches an instance and starts banging away at Outlook.ost file. I can't determine what is causing it.
I'm watching it in processmon, and trying to investigate it with preocessexplorer. Not having much luck at figuring out why the machine is so interested in that file. NOTHING is running that should be touching it.
