Will changing the "Default location for PST files" in the Outlook GPO effect .OST files?

I am getting ready to introduce a new GPO to control AutoArchive within Outlook in the organization. I have a few questions that i cannot find answers regarding some Outlook 2003 GPO's;
1 - Will changing "Default location for .PST files" effect the .OST files? An article here ( http://windowsitpro.com/article/articleid/48228/changing-the-default-location-for-ost-and-pst-files.html ) states a registry change will change the location of both the pst and ost, and i do not want that.
2 - Will this also change the location of the archive.pst since it falls under the default location of .pst files (assuming no archive.pst is present)?
3 - Will this MOVE existing .pst files from the default location to the new one?

I am trying to test these settings to get the answers i need, but I cannot find the time to do so. I cannot seem to find the correct Zone (Zone search feature finds nothing for "Group Policy"). Feel free to re-zone this question.
