I don’t think this is an EE problem, I did some digging into the link previews from Outlook/365 and can’t really find any solid information on how they are generated but some forums threads state it uses the Opengraph tags on the page (usually added by your SEO plugin but it could be done through others or even the theme), others state it does not.
There are a few threads that would point towards outlook caching the previews, for example:
(This cache would be on their end, not yours, so it’s not something you can clear)
You could try contacting 365 support and asking them how the link previews are generated, if the response for the previews are cached and if so, how long its cached and is there a way for your to clear that cache (I don’t think there is).
