Problem with Outlook automatically deleting messages

[Lois M]

After reading received messages in Outlook, Outlook
deletes the message upon closure of the message. The
message just disappears. Doesn't go to the deleted
folder, just disappears. Any help on figuring out the
problem, and how to correct it?? Thanks for your help
with this bizarre problem.

Not bizarre at all.
You have set a filter on your Inbox view, such as "Unread messages" or "Sort
by icon."
Remove it.
