We need to think of a user's mail file and archive as connected facets of the user mail experience. Right now in most domino shops, the person record contains their mail file location, roaming profile database location, public key, sync'd password for sametime/inotes, even businesscard picture. One thing that's missing from the information stored in the person record is the location of the user's primary archive.
I guess ideally, since the archive could be on the server and replicated locally it should have both a path & file name and/or the replica ID of the archive.
This would assist mail file modifications that are designed to make the mail & archive work together seamlessly.
