Can't manage the list of users who can submit in-policy meeting requests for resource mailboxes in an Exchange 2010-based hybrid deployment

Note The Hybrid Configuration wizard that's included in the Exchange Management Console in Microsoft Exchange Server 2010 is no longer supported. Therefore, you should no longer use the old Hybrid Configuration wizard. Instead, use the Office 365 Hybrid Configuration wizard that's available at http://aka.ms/HybridWizard. For more information, see Office 365 Hybrid Configuration wizard for Exchange 2010.
PROBLEM
Assume that you have a hybrid deployment of on-premises Exchange Server 2010 and Exchange Online in Office 365. You discover that you can't use the Exchange Management Console in Exchange 2010 to manage the list of users who can submit in-policy meeting requests to resource mailboxes in Exchange Online.

For example, when you try to add users to the list of users who can book meeting requests (the BookInPolicy parameter) for a room mailbox, you receive the following error message:
The property has an incorrect type: System String. It should be type: Microsoft.Exchange.Data.Directory.ADObjectId.
CAUSE
This behavior is by design.
WORKAROUND

Method 1: Use Exchange Online PowerShell

To use Exchange Online PowerShell to add users to the list of users who can automatically book a room mailbox, follow these steps:
  1. Connect to Exchange Online by using remote PowerShell. For more info about how to do this, see Connect to Exchange Online using remote PowerShell.
  2. Run the following commands:
    $room = Get-CalendarProcessing "Room Name" 
    $room.BookInPolicy += "UserB", "UserC"
    Set-CalendarProcessing room -BookInPolicy $room.BookInPolicy
    Note
    In this example, UserB and UserC are added to the list.

Method 2: Use the Exchange admin center in Exchange Online

To use the Exchange admin center to add users to the list of users who can automatically book a room mailbox, follow these steps:
  1. Sign in Office 365, and then go to the Exchange admin center.
  2. Give the admin account full access to the resource mailbox.
  3. Sign in to Outlook Web App by using the admin account, and then follow these steps:
    1. In the upper-right are of the Outlook Web App screen, click your name, and then in the drop-down list, click Open another mailbox.
    2. Type the email address of the resource mailbox, and then click Open.
    3. In the upper-right corner of the page, click Settings (Screen shot of the Settings icon in Outlook Web  App), and then click Options.
    4. In the left navigation pane, click settings, click resource, and then under These users can schedule automatically if the resource is available and can submit a request for owner approval if the resource is unavailable, click Select users and groups. Then, add the users who you want.
