Allow OneDrive KFM to work with folder redirected folders
Currently (OneDrive client version 18.131.0701.004) Known Folder Migration will not work with known folders that have been redirected. When this is configured, the end user sees "The <folder name> folder contains other important folders and isn't supported for file protection". It seems to want all known folders to be located in their default, local location (C:\Users\<username>\folder) and will not migrate/redirect if they're already being redirected.
The overwhelming majority of enterprise (and smaller) orgs do not store data on local workstations, and I don't see any use case for KFM because of this limitation.
It would be also helpfull if Admins could affect what folders you could redirect like folder redirect does. But it seems that OneDrive need mechanics to handle folder redirection policies like Kevin commented. Because it wont do that At this moment.

I think the need is for KFM to recognize when redirection has been in place and through administrative parameters "re-direct the redirection" into OneDrive for Business without prompting the user. This is what it takes to facilitate enterprises to move from Folder Redirection to OneDrive.
