The command is probably working as it should, you just need to refine the options.
As for permissions, you can add /COPY:DATS to copy security permissions otherwise, NTFS will set inherited permissions from the parent folder.
You should probably avoid MINLAD because last access time is very sketchy. The second someone clicks on the file in explorer, it is accessed. If you want files not modified after 2 days you can use /MINAGE:2
I can get you a better command, if you let us know exactly what you are trying to accomplish. Hope this helps.
