If they have stock outlook they are doing normal networking and are connected to the normal internet over some deep-space antenna setup. So why not just use Debian and gmail in the browser if you want easy? The ISS uses Debian. I can't believe it's too hard to get astronauts to open Firefox

The browser would be far too slow for practical use. Local fist software, which ironically outlook is, would be the way to go.

Does the modern PWA-based outlook even support offline access? I know the old outlook that is no longer being updated does.

Old Outlook still works and is supported until ~2029. We still use it here.

what is old Outlook? for me that's Outlook Express 6 :D

Gmail is not an Outlook replacement. Gsuite as a whole has more or less the required pieces, but there is no single google product that covers the feature set of Outlook + Exchange.
