Configuring Lync Server 2013 to be a partner Application for Exchange 2013

Question

Hello Guys,
I just want to share my experience while configuring Lync server 2013 to be a partner Application for exchange 2013 sever. 
As mentioned on technet you need to run Configure-EnterprisePartnerApplication.ps1 script that ships with Exchange 2013. 
But when I tried to run the script as described on the technet article, I found it always fails with " the accepted domain is not valid"
I have checked my accepted domains many times and i found that there's no issues with my configured accepted domain. 
So I started to review the script to find the issue and I found that the script was configured  as below 
$acceptedDomains = Get-AcceptedDomain ;
  if ($acceptedDomains -eq $null)
    WriteError ("There is no accepted domain so user can not be created.")
  $acceptedDomain = $acceptedDomains[0].Name;
  if($UseDomainController -eq $true)
    $user = New-MailUser -Name $username -DomainController $DomainController -ExternalEmailAddress $username@$acceptedDomain;
set-mailuser -Identity $user.Identity -HiddenFromAddressListsEnabled $true -DomainController $DomainController
  else
    $user = New-MailUser -Name $username -ExternalEmailAddress $username@$acceptedDomain;
set-mailuser -Identity $user.Identity -HiddenFromAddressListsEnabled $true; 
which is totally wrong as below: 
firstly it makes $AcceptedDomain variable to equal the Name of the accepted domain. 
Not all customers configure the name of the Accepted Domain to be the Domain Name.
Secondly  it makes $AcceptedDomain variable to equal the name of the first Accepted Domain.
The first domain may be not the default Accepted Domain. 
So I have configured the script as below
$acceptedDomains = Get-AcceptedDomain | ? {$_.Default -eq "True"}  ;
  if ($acceptedDomains -eq $null)
    WriteError ("There is no accepted domain so user can not be created.")
  $acceptedDomain = $acceptedDomains.DomainName;
  if($UseDomainController -eq $true)
    $user = New-MailUser -Name $username -DomainController $DomainController -ExternalEmailAddress $username@$acceptedDomain;
set-mailuser -Identity $user.Identity -HiddenFromAddressListsEnabled $true -DomainController $DomainController
  else
    $user = New-MailUser -Name $username -ExternalEmailAddress $username@$acceptedDomain;
set-mailuser -Identity $user.Identity -HiddenFromAddressListsEnabled $true; 
I hope This help. 
Thanks
