error enabling Unified Messaging - number already registered

Using skype for business 2015 with exchange online. 

Getting the following error when attempting to enable voicemail for a specific user. 

 

"The phone number you entered has already been registered by someone else"  see attached image

 

confirmed the number is not duplicated in the skype for business control panel using this command:

Get-CsUser | Select-Object DisplayName,SipAddress,LineURI | Export-Csv -Path C:\CsUser.csv -NoTypeInformation

    Hi Brian

     

    This will be indicating a duplicate number within Exchange Online and not Skype for Business on-premises.

      Hi Andrew,

      Thank you for the quick reply.  I did see that site, but

      when I run the following PS command it doesn't find any reslults. 

       

      Get-Recipient -ResultSize Unlimited | where{$_.emailaddresses -like “*EUM:*removed*”} | fl displayname,emailaddresses

        I haven't checked shouldn't it be $_.ProxyAddressess -Like not emailaddresses?
