Ég googlaði og fann þetta:
If your mail disappears as soon as you've read it, it's probably because you're using a read-only view. The default Outlook setting for the preview or reading pane is Mark as read after 5 seconds and when the view refreshes the message is hidden. It's less of a problem with Outlook 2003 because the view isn't refreshed until you leave a folder and return or press F5.
Sem gæti alveg verið skýringin en fann enga möguleika á að breyta þessu!!!
HJÁLP!!! (mamma er að verða brjáluð, er að redda þessu fyrir hana)
