This section provides an overview of the steps to enable Lync for your conference room account, which will be configured on LRS.
After you create a resource mailbox account for the conferencing rooms, use Lync Server Management Shell to enable LRS accounts for Lync services.
The following procedure assumes that you have enabled the LRS account in Active Directory.
1. Run the following command to enable the LRS account on a Lync Server 2013 pool:
Enable-CsMeetingRoom -SipAddress "sip:LRS01@contoso.com" -domaincontroller DC-ND-001.contoso.com -RegistrarPool LYNCPool15.contoso.com -Identity LRS01
Set-CsMeetingRoom LRS01 -domaincontroller DC-ND-001.contoso.com -LineURItel:+14255550555;ext=50555"
Set-CsMeetingRoom -domaincontroller DC-ND-001.contoso.com -Identity LRS01 -EnterpriseVoiceEnabled $true
If you enable Enterprise Voice for the LRS conference room account, make sure to configure a restricted Voice Policy suitable for your organization. If the Lync Meeting Room is a publicly available resource, anyone could use it to join a meeting, either scheduled or ad hoc. After joining a meeting, the person could dial out to any number. In Lync Server 2013, the dial-out from conferences feature uses the voice policy of the user, in this case LRS account used to join the meeting. In earlier versions of Lync Server, the voice policy of the organizer is used. Therefore, if a user of an earlier version of Lync Server schedules a meeting room and invites the LRS room account, anyone could use the Lync Meeting Room to join the meeting and could dial any national/regional or international phone number, as long as the organizer is allowed to dial those numbers.
If for some reason you cannot enable the resource mailbox account in Active Directory and you have used one of the options described in the Alternatives to Enabling Resource Mailbox Account in Active Directory section, you must provide the OriginatorSID while running Enable-CsMeetingRoom cmdlet, as follows:
Enable-CsMeetingRoom -Identity LRS01 -RegistrarPool LyncPool15.contoso.com -SipAddressType SamAccountName -SipDomain contoso.com -OriginatorSid S-1-5-21-2831376166-2963252556-2165051629-1221
The OriginatorSid is taken from any of the authenticating identities (MSA, machine account, or any other enabled user account), because in the previous case, LRS01 is not enabled in Active Directory for log on. Therefore, in the LRS client, you must provide the Sign-In name, for example, LRS01@contoso.com, but the username and password will be the MSA, machine account, or other enabled user account.
If you need to move the LRS account from one Lync Server 2013 pool to another Lync Server 2013 pool (for example, during upgrades), use the following cmdlet to move the LRS account pool:
Move-CsMeetingRoom -Identity LRS01 -Target "LYNCPool15-2.contoso.com”
If you need to disable an existing LRS account from Lync services on a Lync Server 2013 pool, use the following cmdlet to disable the account:
Disable-CsMeetingRoom LRS01 -domaincontroller DC-ND-001.contoso.com
