If you have Outlook configured as POP3 on a laptop, every time you login it will download all the mails from the server and unless you have ticked the box to leave a copy on the server, will also delete them on the server.
BTW, I think you mean change to IMAP, not SMTP, SMTP is the send protocol not receive.
As per my message 2 para 4 if it was set up as POP3 set to delete from the server, the messages would have been downloaded to that client and be available there.
I should have gone to Specsavers 😁
