Selectively Enabling Users for Unified Contact Store

As noted previously, unified contact store automatically becomes available and is enabled when the environmental and systems prerequisites are met. However, in some network envrironments it might be advantageous for a Lync administrator to selectively enable users for unified contact store. This can be accomplished using several Lync Server Management Shell cmdlets that were created for this purpose. Using these cmdlets, users can be enabled globally, by site, by individual user, or by distribution group.

Since unified contact store is enabled by default, if selectivity will be used it is first necessary to disable the feature globally. The following procedure would be used to globally disable the users for unified contact store using the Lync Server Management Shell:

1. Log on to a system where the Lync administrative tools are installed using an account that is a member of the CsAdministrator group, and has administrative rights on the local system.

2. Open the Lync Server Management Shell, and execute the following cmdlet to disable unified contact store for all users:

Set-CsUserServicesPolicy -Identity global -UcsAllowed $False

After unified contact store has been disabled globally, it can be enabled selectively. For example, the following command would be used to enable the feature for a specific site, in this example, the site named SF:

New-CsUserServicesPolicy -Identity SF -UcsAllowed $True

To selectively enable individual users for unified contact store, the user policy must first be created, and then applied to the user accounts. For example, the following two commands would be used to first create a policy for enabling the users, and then apply the policy to an individual user:
