Read this topic to learn how to deploy Skype Room System in a multiple forest on-premises environment.

In order to deploy in multiple forests, Skype Room System requires Exchange Server 2013 CU6 released on August 26, 2014. Avoid re-using an existing mailbox for Skype Room System. Use a new (delete old mailbox and re-create) resource mailbox for Skype Room System. To restore the meetings lost by deleting the mailbox, see Connect or restore a deleted mailbox.

After creating the mailbox, you can use Set-CalendarProcessing to configure the mailbox. Refer to steps 3 through 6 under Single forest on-premises deployments for more details. After creating an Exchange Resource mailbox for Skype Room System, enable the account for Skype for Business by following the steps in Enabling Skype Room System Accounts for Skype for Business under Single forest on-premises deployments.

To deploy Skype Room System in a multi-forest environment:

  1. Create a Linked User (LinkedRoomTest) in Active Directory (Authentication Forest).

  2. Run the following commands in the Exchange Server Management Shell:

$cred = Get-Credential AuthForest\LinkedRoomTest
new-mailbox -Alias LinkedRoomTest -LinkedMasterAccount AuthForest\LinkedRoomTest -LinkedDomainController -UserPrincipalName LinkedRoomTest@ExchangeForest.contoso.comm -Name LinkedRoomTest -LinkedCredential $cred -LinkedRoom

$cred=Get-Credential AuthForest\LinkedRoomTest1
Set-mailbox -Alias LinkedRoomTest1 -LinkedMasterAccount AuthForest\LinkedRoomTest1 -LinkedDomainController -Name LinkedRoomTest1 -LinkedCredential $cred -Identity LinkedRoomTest1
