I get Invalid parameter with this icacls line

Question

icacls d:\users\dptname\username /grant:W company-domain\username:(OI)(CI)(M)

error says: invalid paramter "/grant:W"

why?

Answer 1

I got it. company-domain\username should be in quotation marks...

Answer 2

grant:W 

is not valid because the only valid switch is

grant:r

or no switch at all. From the documentation

With :r the permissions replace any previously granted explicit permissions.
Without :r the permissions are added to any previously granted explicit permissions
