Oh yes, I was once working for a large arts organisation of about 100-150 staff, and they migrated their entire server to OneDrive... (This was before SharePoint was released) And holy moly!! Imagine 150 staff using the same server, it was insane... So slow, and constantly syncing, clogged the entire internet speed, but was insanely inaccurate with multiple different copies of files that multiple people had open.
They decided to use it as a file storage server because it was easy to drag and drop files to upload and store etc. But the younger gen and the technologically savvy were using it more for the cloud based and auto save functionalities. But that cause worse issues because you had 2 different groups of people using the software differently and it really couldn’t keep up. Worst year ever.
