hotmail only supports POP, a very outdated email system where messages are downloaded to the device and handled there entirely
if microsoft enabled IMAP in hotmail, which is much better, changes made on one device are reflected on the server, and therefore on all other devices which access your email
you'll need to switch to gmail or another provider for this, it took M$ years to add POP, which has been outed years ago by all other mail providers for IMAP/exchange
