2687404 extracts to a many launguage specific msp files and the outlook-x-none.msp. The outlook-xx-xx.msp should be matched to the language version you have installed.
3863811 extracts to only outlook-x-none.msp. The language files are not present so installing only this msp will not apply the updates to the language files.
It is possible that not all of the files listed on the webpages may be present if they are related to Outlook features which are not installed.
outlook-x-none.msp in the 3863811 is a later version and carries later versions of some of the files.
The suggested approach would be to install outlook-xx-xx.msp for the language version updates and the outlook-x-none.msp via the updates folder to achieve the latest updates installation for Outlook 2007.
Note that if both outlook-x-none.msp files are renamed and copied to the update folder, then only the later one is applied because the installer scans the folder first to determine which are the latest updates to apply.
