I too am having this issue. Now with the Sync option Jazlyn Xu gave for us this didn't work and I wanted to explain because this caused a lot of issues for us. We moved our entire File Server files up to SharePoint so we could stop using internal servers and so our "in the field" users can access everything while outside the office. We originally did the sync of these folders, but what happened was having 40 computers all trying to sync the same SharePoint/OneDrive folders no one could make changes. All changes and deletes got overwritten and put back by the other 39 computers all fighting to sync too. So we had to remove the sync off all 40 computers to stop this from happening. "This was VERY time consuming."
We then started using the SharePoint Web access way of doing things to access our documents and would like to know how to drag and drop a file from SharePoint/OneDrive to Outlook. We can't drag and drop to our desktop either but can drag and drop to SharePoint.
