I have recently installed the latest version of Outlook & windows on  my new laptop. When I am in outlook and receive email on my new laptop, I can read it with no problems, however,  if I open the email on my desktop, it completely disappears from my laptop within a minute. If I do not open it on my desktop, it stays in my laptop inbox.

Why would it delete from my inbox on my laptop? What can I do to keep it on my laptop?

Thanks, Orie
