In recent weeks whenever I install Office 2007 on a computer it changes the default file location for the .ost file in Outlook. It should be in c:\local settings\application data\Microsoft\outlook. Instead it's putting the file in the H drive on our file server. We use the H drive for people to have their own folders on the network that get backed up. We usually create PST files in this folder but the ost files we want to stay on the local machine. This is happening automatically during the setup of Outlook 2007. Even if it's an upgrade from 2003 this seems to be happening although it just seems to be doing it when configuring the mail account on a laptop and using Cached exchange mode. This defeats the purpose of cached exchange mode since we want people with laptops to have a copy of their inbox on their computers in case they want to work on a plane or someplace else where there are no internet connections. I install Office 2007 from a network share with a setup file that enters the product key and other information in there automatically. I've checked that and there aren't any settings that would cause this. Can anyone help me out?
