Sorry, none of what you just said makes any practical sense.
Outlook freezes all the time. And in the past year or so AI “helpers” became very intrusive and distracting.
Office 365 usually has an authentication snafu twice a year-those days are completely lost for me. But even in the days without outages Office 365 is glitching and requires multiple attempts to login.
Or maybe he in fact is not logged into onedrive, and 365 simply sucks.
