I work at a private university that has gone all-in with MS. We have OneDrive and I believe custom BGP routes straight to Azure with 200G pipes.

This product is complete garbage. I try to upload/share large files to individuals within the institution. It constantly fails when upload or downloading anything over 5GB. The pipe to my desk is 1000/1000. What is the issue? Is OneDrive literally only meant to be used for documents yet we're told by central IT to use it for research data?
