Currently you can only select the destination server for server side archiving in the Archive settings document.  Many users would only have one archive settings document applied to them which means archiving can only be pushed to one archive server.  If we moved the destination server into the archive criteria we could have one archive settings document per user but several archive criterias pointing to different servers.  We have a client who needs to archive to a different archive server each year due to the massive amount of archived mail.  Currently the archive criteria document only allows you to select a file destination.  If we could add the server destination to the archive criteria document we could create a new criteria each year which points to a new server and maintains the other criterias.  Hope this makes sense.  Cheers,
