I have a couple of questions about using Outlook with an IMAP email account.

I just set it up on our PC (shared between me and my wife but logging in under
different profiles). Now, she's been using our ISP's webmail service for some
time now as she's been moving between her laptop and this computer. So I decided
to configure Outlook for IMAP operation to see if the same email base can be
shared between the two or more machines.

It auto configured OK (it detected IMAP first). It then downloaded a lot of
messages that were stored on the server side of things.

I had a look at one then I deleted it. Instead of it going to the deleted items
folder Outlook merely put a strikethrough or a line through the message title
which you see in folder view or whatever it's called.

How does Outlook delete it in the conventional sense?

Thanks.
