Microsoft-Office-2021 VS onedrive

here's a hunch assuming you tried the below client:

https://github.com/abraunegg/onedrive/blob/1a88d33be3e2c6747...

try changing that to e.g. the android (or windows) onedrive client's id.

this trick works for exchange (allowing third-party mail clients).

Syncthing might fit the bill, or just keep using Onedrive: https://github.com/abraunegg/onedrive

I first started with this onedrive client https://github.com/abraunegg/onedrive (+ the GUI package) and got it working fine, but it seems like a sync all-or-nothing deal.

You could check out https://abraunegg.github.io/, I use that for syncing with my OneDrive.

* Via the OneDrive Client for Linux - https://github.com/abraunegg/onedrive - this 'syncs' your data, bi-directional operation, open source and free. Supports Personal, Business & SharePoint account types and Shared Folders. A Docker container is also available for all major architectures (x86_64, ARMHF, AARCH64). If you need a GUI for onedrive client management use: https://github.com/bpozdena/OneDriveGUI

I have used an app called, appropriately, onedrive. The git repository and info is here. Once you connect to OneDrive (not hard to do at all) you can do anything in the folder and when you start the command from the CLI it will sync the files to your account and update the files on the server. There are a few custom options you can set to streamline. I used it for a long time syncing with Windows and it works great.

The client itself is 100% stable and functional enough for your use-case. To read up on the client, please visit: https://github.com/abraunegg/onedrive
