Enable Users for Unified Contact Store

Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2013, and then click Lync Server Management Shell.

Do any of the following:

• To enable unified contact store globally for all Lync Server users, at the command line, type:
  
  Copy

  Set-CsUserServicesPolicy -Identity global -UcsAllowed $True
  

• To enable unified contact store for the users at a specific site, at the command line, type:
  
  Copy

  New-CsUserServicesPolicy -Identity site:<site name> -UcsAllowed $True
  

  For example:
  
  Copy

  New-CsUserServicesPolicy -Identity site:Redmond -UcsAllowed $True
  

• To enable unified contact store by tenant, at the command line, type:
  
  Copy

  Set-CsUserServicesPolicy -Tenant <tenantId> -UcsAllowed $True
  

  For example:
  
  Copy

  Set-CsUserServicesPolicy -Tenant "38aad667-af54-4397-aaa7-e94c79ec2308" -UcsAllowed $True
  

• To enable unified contact store for specific users, at the command line, type:
  
  Copy

  New-CsUserServicesPolicy -Identity "<policy name>" -UcsAllowed $True
  Grant-CsUserServicesPolicy -Identity "<user display name>" -PolicyName <"policy name">
  
  

  Note:
  You can also use user alias or SIP URI instead of the user display name.

  For example:
  
  Copy

  New-CsUserServicesPolicy -Identity "UCS Enabled Users" -UcsAllowed $True
  Grant-CsUserServicesPolicy -Identity "Ken Myer" -PolicyName "UCS Enabled Users"
  
  

  Note:
  In the preceding example, the first command creates a new per-user policy named UCS Enabled Users with the UcsAllowed flag set to True. The second command assigns the policy to the user with the display name Ken Myer, which means that Ken Myer is now enabled for unified contact store.
