Here is how to do it! Note, this is copied right from Microsoft's website for archival purposes. Here is a link to the technet article: http://technet.microsoft.com/en-us/library/gg413062.aspx
- Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Management Shell.
- Run the Set-CsUser cmdlet to configure the user account for hosted voice mail. For example, run:
Set-CsUser -HostedVoiceMail $True -Identity "contoso\kenmyer"
The preceding example sets the following parameters:
- HostedVoiceMail enables a user’s voice mail calls to be routed to hosted Exchange UM. It also signals Microsoft Lync 2010 to light up the “call voice mail” indicator.
- Identity specifies the user account to be modified. The Identity value can be specified using any of the following formats:
- The user's SIP address
- The user's Active Directory User-Principal-Name
- The user's domain\logon name (for example, contoso\kenmyer)
- The user's Active Directory Domain Services Display-Name (for example, Ken Myer). If using the Display-Name as the Identity value, you can use the asterisk (*) wildcard character. For example, the Identity "* Smith" returns all the users who have a Display-Name that ends with the string value "Smith".
