On a few instances after copying another LiveID contact.ebd file to the default DBStore folder, I've seen the Live ID of the
source contacts.edb displayed when viewing the default contacts.
Never did investigate if itâ€™s a supporting file or the contacts.edb file, thus I've always deleted the subfolders and files under
the default DBStore, which seems to do the trick.
Two possibilities come to mind - one of the supporting files is responsible or the contacts.edb is involved until its updated and
saved by WLM...or a third(a combination)
