Effective planning for integrating Lync Server 2010 with hosted Exchange Unified Messaging (UM) requires that you take into account the following:

Deployment Prerequisites for Integrating with Hosted Exchange UM

Before you can begin the integration process, you must already have deployed Lync Server (at a minimum, a Front End pool or a Standard Edition server), an Edge Server, and Lync 2010 or Office Communicator 2007 R2 clients.

Integration Process

The following table provides an overview of the hosted Exchange UM integration process. For details about deployment steps, see Providing Lync Server 2010 Users Voice Mail on Hosted Exchange UM in the Deployment documentation.

Configure hosted voice mail policy.

  1. Either modify the global hosted voice mail policy or create a new hosted voice mail policy with Site or Per-User scope.

  2. For policies with Per-User scope, assign the policy to users or groups.


Manage Hosted Voice Mail Policies

Enable users for hosted voice mail.

  • Configure user accounts for users whose mailboxes are on a hosted Exchange service.

Configure hosted contact objects.

  1. Create auto-attendant Contact objects for hosted Exchange UM.

  2. Create Subscriber Access contact objects for hosted Exchange UM.


To create, modify or remove contact objects, the user who runs the New-CsExUmContact, Set-CsExUmContact or Remove-CsExUmContact cmdlet must have the correct permission to the Active Directory organizational unit where the new contact objects are stored. This permission can be granted by running the Grant-CsOUPermission cmdlet. For details, see the Lync Server Management Shell documentation.
