Andrew,
The Get-UMMailbox | fl Extensions was very helpful. I see the ext "7832" I'm trying to apply assinged to another user. Can you advise the best way to change this? Can I just disable UM for the user with 7832.. then re-enable with the correct ext. Then attempt to enable 7832 to the correct user?

  Hi Brian
  
  At the moment, the supported method is to disable UM for the user and re-enable. Any previous voicemails, greetings and settings will be reainimated when enabled again.
  
  thanks

    Hi Mark,
    I've tried disabling um.. but it won't let me change the ext saying it's sycned with active directory. When I look at the AD user attributes, they match what the skype for business 2015 server says.
