Plex and Onedrive

How do I set up plex to play movies from onedrive - I cant find Plex Cloud so I cant add onedrive

As far as I know the movies need to be downloaded, synced, to a local drive. Happy to be corrected by someone who knows better but I do not think that plex can read and use files stored in the cloud

Plex Cloud was discontinued years ago.

Plex Media Server expects to see media stored on a file system native to the platform where it is installed. For example, c:\media on Windows or /media on Linux.

To make cloud storage appear as a local file system, use rclone or similar third party tools.

Search the Plex forum for rclone for additional details or see the rclone user forum.
