Messages disappearing

[Midmarketeer]

If I click on the Deleted Items folder, the message I was clicked on and all
the messages above that one in my Inbox completely disappear.

What can I do to stop this happening?

I always either move my read messages to folders or simply delete them. I
never leave them in the In-box after being read. So, I have to ask you this
:
In you In-box, is it arranged in such a way that all read messages are at
the top of the list, un-read messages are at the bottom ?
If yes, then perhaps they are just being " hidden " when you click a
different folder.
Try this : Open Windows Mail > top, click View > Current View > choose "
Show all messages "
Now, open your In-box. Are the read messages back on ?
