A Microsoft file hosting and synchronization service.
Hi, Mia; I understand the awkward situation you are in where someone up the chain removed a feature and then has left you to deal with us angry users who no longer have local control over our own files. You need to know that the "Always keep on this device" solution simply doesn't work. I'm a pretty savvy user of both Microsoft and Apple products (I started with Microsoft Office 1.05 in 1984 and bought my first Mac shortly thereafter) and something doesn't work with macOS Monterrey and OneDrive. Microsoft should never have forced us to use Files on Demand in the first place. I know you didn't make that decision, but you have closer access to that person than any of us posting here.
The only solution I have is to download all my files and leave OneDrive. For those who might be reading, head over to insynchq.com and you'll find a convenient way to access your OneDrive files and keep local copies by default on your computers. And it works with Linux.
I appreciate your understanding, Mia, and trust you'll leave this post up so users can make their own decisions regarding their files. Have a wonderful day.
