A positional parameter cannot be found that accepts argument

Question

Hi All

I used the following syntax to grant "TempPolicy1" globally. However, I am encountering an error while trying to remove this policy "TempPolicy1" globally Please guide me.

Grant-CsApplicationAccessPolicy -PolicyName "TempPolicy1" -Global

i have used below syntaxes

Grant-CsApplicationAccessPolicy -PolicyName "TempPolicy1" $Null -Global

Grant-CsApplicationAccessPolicy : A positional parameter cannot be found that accepts argument '$null'.  

Grant-CsApplicationAccessPolicy -PolicyName "TempPolicy1" $Null

Grant-CsApplicationAccessPolicy : Cannot bind argument to parameter 'Group' because it is an empty string.

Answer 1

Hi, @Roger Roger

According to your description, you want to remove the policy globally.

You are trying Grant-CsApplicationAccessPolicy, but an error occurs due to the parameter '$Null'. In fact, the “Grant-CsApplicationAccessPolicy” cmdlet does not accept the '$Null' parameter.

To globally remove a policy, the correct syntax should not include $null. Instead, you should use the Remove-CsApplicationAccessPolicy cmdlet to remove the policy.

Remove-CsApplicationAccessPolicy -PolicyName “TempPolicy1” -Global

Answer 2

i have used the below syntaxes i am getting the error.

Remove-CsApplicationAccessPolicy -identity "TempPolicy1" -Global

Remove-CsApplicationAccessPolicy "TempPolicy1" -Global

Remove-CsApplicationAccessPolicy -identity "TempPolicy1"

Remove-CsApplicationAccessPolicy -identity "TempPolicy1" -global $null

Answer 3

For that last error, you have to remove the policy from any users to which the policy has been assigned. To do that you assign the policy $null to the user. Use the Grant-CsApplicationAccessPolicy to do that.

The Remove-CsApplicationAccessPolicy cmdlet removes the policy itself.

Answer 4

In addition to the answers given by @Anonymous (using the correct cmdlet) when you mix positional and named parameters the positional parameters must precede any named parameters.

For example:

Fictional-CmdletName1 -NamedParameter1 "TempPolicy1" $Null -NamedParameter2
Should be:
Fictional-CmdletName1 $Null -NamedParameter1 "TempPolicy1" -NamedParameter2

Fictional-CmdletName1 -NamedParameter1 "TempPolicy1" $Null
Should be:
Fictional-CmdletName1 $Null -NamedParameter1 "TempPolicy1"
