Re: I really can't understand what some people consider trustworthy...
It's quite common that corporate mail servers will block encrypted/password protected zips as attachments, as they can't be virus scanned. This can lead to people sharing files via One Drive links. The article mentioned One Drive as one of the services used.
So I can see how it would be plausible, based on how we are restricted to sharing files with some clients.
I also had a manager who used to use drop box to share training videos. This was before the age of teams and one drive became prevalent, and a much better method to use
