You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Recipient Provisioning Permissions" section in the Mailbox Permissions topic.

1. In the console tree, navigate to Recipient Configuration > Mailbox.
   
   
2. In the result pane, select the resource mailbox that you want to configure.
   
   
3. In the action pane, under the name of the resource mailbox, click Properties.
   
   
4. On the Resource In-Policy Requests tab, configure the following settings:
   
   
   • All Users   Select this option to allow all users to submit requests within the resource policy's configuration.
     
     
   • Selected recipients   Select this option to specify who can submit requests within the resource policy's configuration. If you select this option, you need to click Add to select the recipients. You can also remove selected recipients by clicking Remove.
     
     
5. On the Resource Out-of-Policy Requests tab, specify the users who can submit out-of-policy requests. Users who can submit out-of-policy requests won't have their request denied, but the requests will require approval by one of the resource's delegates. Configure the following settings:
   
   
   • All users   Select this option to allow all users who submit resource requests that don't meet the resource policy's configuration.
     
     
   • Selected recipients   Select this option to add specific users who are allowed to submit out-of-policy requests. If you select the Selected recipients option, you need to click the Add button to select the recipients. You can also remove selected recipients by clicking Remove.
     
     

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Recipient Provisioning Permissions" section in the Mailbox Permissions topic.

To control who can schedule a resource, use the following parameters with the Set-CalendarProcessing cmdlet:

• AllBookInPolicy
  
  
• AllRequestInPolicy
  
  
• AllRequestOutOfPolicy
  
  
• BookInPolicy
  
  
• RequestInPolicy
  
  
• RequestOutOfPolicy
  
  
• ProcessExternalMeetingMessages
  
  

Note:
When AllRequestInPolicy and AllRequestOutOfPolicy are both set to True, only out-of-policy requests are forwarded to delegates. Exchange Server automatically accepts in-policy requests, and does not forward the policy requests to a delegate.

This example allows the Calendar Attendant to approve in-policy requests from all users for the room mailbox 5th Floor Conference Room.

	Copy Code
Set-CalendarProcessing -Identity "5th Floor Conference Room" -AutomateProcessing AutoAccept -AllBookInPolicy $true

This example allows all users to submit in-policy requests to the room mailbox 5th Floor Conference Room, but the request is still subject to approval by a delegate.

	Copy Code
Set-CalendarProcessing -Identity "5th Floor Conference Room" -AutomateProcessing AutoAccept -AllRequestInPolicy $true

This example allows the Calendar Attendant to accept out-of-policy requests from Alan Brewer to the room mailbox Room222. The request is still subject to approval by a delegate.

	Copy Code
Set-CalendarProcessing -Identity "Room222" -AutomateProcessing AutoAccept -RequestOutOfPolicy AlanBrewer@contoso.com

This example allows a list of users to submit in-policy meeting requests to the equipment mailbox Car54.

	Copy Code
Set-CalendarProcessing -Identity "Car54" -AutomateProcessing AutoAccept -BookInPolicy "ayla@contoso.com","tony@contoso.com"

This example rejects meeting requests from any user who isn't a member of the Exchange organization.

	Copy Code
Set-CalendarProcessing -Identity "Room222" -ProcessExternalMeetingMessages $false

For detailed syntax and parameter information, see Set-CalendarProcessing.

After you specify which users can send meeting requests to resource mailboxes, you may also want to set a delegate on a resource mailbox. For detailed steps, see Set a Delegate on a Resource Mailbox.
