I am asking this question for someone else, not myself, so I don't know if I will be able to adequately explain the problem. They are using Outlook 2000. I was told that one day all the messages disappeared in the INBOX and the DELETED ITEMS folders. Apparently there were quite a few files. Any new files since that day do appear.
We checked the VIEW>CURRENT VIEW menu and the MESSAGES was checked.
They told me they did not do anything out of the ordinary, so program installation, etc.
Appreciate any insight.
