By default, PST and OST files are located in: %userprofile%\Local Settings\Application Data\Microsoft\Outlook. You can use this setting to specify a different folder location for PST and OST files. The setting "Default location for OST files" can be used to provide a new location specific to OST files, overriding this setting (for OST files only).
