I'm having an issue with Outlook on my desktop PC so am having to use my laptop instead. Unfortunately, my email is currently POP3 so not able to sync them

It's installed fine on my laptop but on here, the recycle bin is only displaying the few emails that have come through since, not all my historical ones that are there (& are visible on my desktop MW Pro)
Does anyone know how I can have the 2 MW Pros synced to show ALL mail on BOTH ?
Also, I've duplicated my MW Pro desktop configurations/display settings screen by screen but on my laptop, the display colours aren't reflecting ?
