I signed into outlook on a friend’s laptop in 2016/2017. Just got a windows and found out most of thier photos ended up saved on my account.

They must have realized at some point because there hasn't been anything since late 2017 (and the laptop doesn't show up in the Device List), but I'm kinda freaked out because all I did before was sign in to check my email on a mail app. Then again, it was a while ago and I'm not sure he had an account signed yet, so I may have signed in to the whole computer without realizing. I also feel horrible because there's about 2 year's worth of family photos from a guy I haven't even talked to in years.
