messages view shows only unread messages

[Jay L]

I don't know what I've done wrong but I have 1759 messages in my inbox
but when I select 'messages' as my view I only see the unread ones. I
can switch back and forth from messages to unread messages and nothing
changes.

The messages are there. If I change to one of the other views "by
sender" for example ...all the messages are there. If I search from
the 'messages' view it finds messages I can't see in that view and I
can open them fine.

Ideas/suggestions would be much appreciated.

Thanks,
