I would like to be able to exclude the Inbox folder from the Archive process. I archive fairly frequently to keep my server space under control and many times still have things in my Inbox that need to stay there until they are resolved but they get archived. At that point I have to go find them in the archive and drag them back to the appropriate inbox.
On a grander scale, I also agree with a previous request that it would be nice to be able to change archive settings on a folder by folder basis.
