sorry, the correct first line is followng.
PS O1:\総務部> Add-OrchFolderUser 'Automation Users',

I mistakenly pasted as
PS O1:\総務部> Add-OrchFolderUser 'Automation Users',everyone
but the last "everyone" is the predicted text and I didn't type it.

I found ParameterSetName attribute usage was incorrect in my code. I fixed it and the problem gone. I am sorry for bothering you. Thanks.
