Lync Online Provisioning 

After a resource room mailbox account has been created and enabled as shown previously, the account will synchronize from the Exchange Online forest to Lync Online forest by using the Windows Azure Active Directory forest. The following steps are required to provision the LRS account in the Lync Online pool. These steps are the same for both an existing resource mailbox account or a newly created account (confrm1 or confrm2), because once they are enabled in Exchange Online, both of these accounts will be synchronized to Lync Online in the same way.

  1. Create a Remote PowerShell session. Note that you will need to download Lync Online Connector Module and make sure that your computer is configured. More details can be found at http://technet.microsoft.com/en-us/library/dn362839.aspx.

PS C:\Windows\system32> Import-Module LyncOnlineConnector

PS C:\Windows\system32> $cssess=New-CsOnlineSession -Credential $cred

PS C:\Windows\system32> Import-PSSession $cssess

 

  1. To enable an LRS account for Lync, run the following cmdlet:

PS C:\Windows\system32> Enable-CsMeetingRoom -Identity $rm -RegistrarPool "sippoolbl20a04.infra.lync.com" -SipAddressType EmailAddress

You can obtain the RegistrarPool address where your Lync users are homed from one of your existing accounts by using the following cmdlet to returns this property, (among others:

PS C:\Windows\system32> Get-CsOnlineUser -Identity ‘alice@contoso.onmicrosoft.com’

 

  1. If you would like to enable Enterprise Voice features for the Lync Room System account, and you have Lync Online (Plan 3) licenses available, you can assign an available line URI by using the following command:

PS C:\Windows\system32> Set-CsMeetingRoom confrm1 -LineURI "tel:+14245231111"

  1. You can choose a telephony provider for this account by using the Lync Online Control panel.
