My work laptop has a weird combination of a personal microsoft account that (I think) is linked to the windows licence, and a corporate account that is linked to O365, sharepoint, etc. Office works, as does OneDrive [1], but I've never been able to access SharePoint (probably not a bad thing). Azure just doesn't work for me, and even Microsoft support couldnt figure out why. I'm usually pretty positive about Msft but their identity stuff is a mess. [1] except that I have two OneDrives that appear to form a Venn diagram with a partial intersection that i can never quite figure out....
