Download Mountain Duck as an alternative to the One Drive client from Microsoft.
Microsoft Graph, OneDrive, and SharePoint support using a standard OAuth2 authorization flow.
The OneDrive connection profile is bundled by default and connects to the endpoint
https://graph.microsoft.com/v1.0/me. Login with your personal or business account to
login.microsoftonline.com when prompted to grant access to Cyberduck.
OneDrive uses OAuth 2 for authentication with
graph.microsoft.com. When opening a connection, a web browser window is opened to grant access to OneDrive for Cyberduck.
The authorization code will be submitted to Cyberduck automatically. Subsequent connections will not require authorization, unless the refresh token itself is expired due to inactivity.
You can connect to multiple accounts at the same time. Create a new bookmark for every account and run through the OAuth flow. Make sure to log out of any account in web browser before triggering the OAuth flow for a new account.
Reset OAuth Tokens
If you have accidentally logged in with the wrong OneDrive Account or want to change the login of the OneDrive bookmark delete the current bookmark and create a new one to start a new authentication flow.
Alternatively, you can reset the OAuth token by deleting the entries related to
duck:onedrive?user=(user) out of the Windows Credential Manager or on macOS the entries related to
login.microsoftonline.com out of Keychain Access.app.
All authentication codes expire after 90 days. If you get the error message
Forbidden. The caller doesn't have permission to perform the action. [...] due to this known issue you need to reauthenticate by performing an OAuth Reset.

Refer to the Cyberduck CLI documentation for more operations. For subsequent invocations make sure to include the
--username parameter and set it to the email address registered with Microsoft to allow the lookup of previously saved OAuth tokens.
You can search recursively for files fast without browsing folders first.
A list of file versions can be viewed in the Versions tab of the Info window. Files can be reverted to a chosen version of this list.
There are some limitations that you should keep in mind while working with.
We’ve added support for Microsoft 365 China in Cyberduck 7.8 / Mountain Duck 4.4 but aren’t able to verify if it works properly.
No interoperability with Microsoft 365 for US Government (other services may apply as well)
Native file locking only exists for OneDrive Business (Microsoft 365 Business), it is not supported for regular consumer use.

It is not possible to create a top level folder in Mountain Duck or Cyberduck. Instead, the following virtual top level folders are displayed which cannot be moved or renamed:
Mountain Duck can only display the correct cloud storage quota as remaining disk space when setting the Path in the bookmark configuration to a folder different from
/, for example
