I think this arrived in Release: 2.0.3.4 (canary) 2018-04-02. Pull request: Add new backends for OneDrive + OneDrive for Business, SharePoint, and Microsoft Groups based on the Microsoft Graph API #3118
EDIT: I’m not sure what I saw before, but I transcribed 2.0.3.3 beta and 2.0.3.11 canary Storage Type values:
2.0.3.3 Beta
Microsoft OneDrive
Microsoft OneDrive for Business
Microsoft SharePoint
2.0.3.11 Canary
Microsoft Office 365 Group
Microsoft OneDrive
Microsoft OneDrive for Business
Microsoft OneDrive v2
Microsoft SharePoint
Microsoft Sharepoint v2
I’m concerned about timing, due to Microsoft’s deadline, and this feature only being in canary release so far. Possibly migration aids and/or publicity is advisable in order to reduce broken backups come November 1st. Doing another Beta has been a desire, but I’m not sure when it will happen or if an Experimental would help.
Old OneDrive API being deprecated - needs to be rewritten to use the Graph API #3024
Now back to the actual latest question 
, I don’t run Docker but I’m wondering if psywolf85 runs CLI or web.
$ duplicati-cli help onedrivev2
Microsoft OneDrive v2 (onedrivev2): <etc.>`
is one way to see if at least that code knows onedrivev2. Also check web About --> System info version info, consider possibility of browser needing a page refresh, cache clear, restart, or whatever (maybe view is old).
