Remove an audio conferencing provider previously assigned to a user in Skype for Business Online
Topic Last Modified: 2013-07-05
To remove all the audio conferencing providers assigned to a user, run the Remove-CsUserAcp cmdlet without any parameters (other than the Identity parameter, which indicates the user in question):
Remove-CsUserAcp -Identity "Ken Myer"
If a user has been assigned multiple audio conferencing providers, you can remove a single provider by including the Name parameter, followed by the name of the provider to be removed:
Remove-CsUserAcp -Identity "Ken Myer" -Name "Contoso ACP"
