Can't get a specific atribute to work with Set-ADUser

We are trying to set up a script to add user into skype. One of the settings we need is msRTCSIP-UserRoutingGroupId. Here is the command we are trying to use the rest of the script works when we don’t run this line.


Set-ADUser -identity $user -Add @{‘msRTCSIP-UserRoutingGroupId’=‘<HEX>’;}

This is the error message we get.

Set-ADUser : A value for the attribute was not in the acceptable range of values
At line:1 char:1

  • Set-ADUser -identity $user -Add @{‘msRTCSIP-UserRoutingGroupId’='42 9 …
  • CategoryInfo : NotSpecified: (jack.yorgesen:ADUser) [Set-ADUser], ADException
  • FullyQualifiedErrorId : ActiveDirectoryServer:8322,Microsoft.ActiveDirectory.Management.Commands.SetADUser


Any ideas on why this won’t work would be appreciated
