Even if SharePoint and OneDrive have different purpose for users, their backends are continuously merging. And the document management system is a good example of this.
The ability of every user in the enterprise to use an online document (upload, modify, download) from OneDrive, SharePoint or even Microsoft Teams is based on your IT department’s ability to provide seamless service.
But this service includes a lot of moving parts—your route to the cloud, your ISP, your network and your infrastructure. Finally, of course Microsoft service itself plays a role in the service for which you are responsible.
To add to this complexity, new features of a specific workload like Microsoft Teams can have an impact on the overall performance of another workload like OneDrive, adding stress to your network.
