Printer QR-Code in Visual C# Figure 6-44 Including rooms in an OWA meeting request.

You can discover the current set of room mailboxes with this command:

Name ---Conference Room 14341 Executive Conference Room Preston Conference Room Liffey Conference Room London Conference Room Lisbon Conference Room Longford Conference Room Leitrim Conference Room Liverpool Conference Room Leixlip Conference Room

ResourceCapacity ----------------

16 24 24 50 100

ResourceCustom --------------{} {} {} {} {Concall} {Concall} {} {Concall} {Whiteboard, Concall, HALO} {TV}

We see two properties listed that can be used to communicate details about the rooms to users when they decide which room they d like to book. The ResourceCapacity property is

used to state the number of people that can fit in the room. This is purely advisory because Exchange doesn t apply any intelligence to meeting requests to check that the number of attendees listed doesn t exceed the capacity of the selected room. The ResourceCustom property allows administrators to indicate whether anything special is available in the room. Before you can populate any value into the ResourceCustom property, you have to create a set of custom properties for the resource configuration with the Set-ResourceConfig cmdlet. For example, this command creates a basic set of different items that you might find in a room:

Set-ResourceConfig ResourcePropertySchema ("Room/TV", "Room/Concall", "Room/HALO", "Room/Whiteboard", "Room/Video", "Room/ComfortableChairs")

You ll note that the resource values can t have spaces. There is no UI in EMC or ECP to manage the set of custom properties. If you need to update the set of custom properties you can either rewrite the complete set or update the current set with a few lines of EMS code. For example:

$CurrentConfig = Get-ResourceConfig $CurrentConfig.ResourcePropertySchema+="Room/PictureWindow" Set-ResourceConfig ResourcePropertySchema $CurrentConfig.ResourcePropertySchema

Note that the set of custom properties can also contain properties that are used to differentiate equipment mailboxes. All of the entries in the set that we have seen so far are prefixed with Room/ so Exchange knows that these properties only apply to room mailboxes. Properties used with equipment mailboxes are prefixed with Equipment/ and can be added as described earlier. Once the resource configuration is populated, if a room is equipped with the HP Halo Communications System, this could be indicated as such by setting the property as follows:

Set-Mailbox Identity 'Liverpool Conference Room' ResourceCustom ('HALO')

This command will overwrite any existing custom properties that exist for the mailbox. If multiple custom resources are available in a room, you can populate them like this:

Set-Mailbox Identity 'Liverpool Conference Room' ResourceCustom ('HALO', 'Concall')

Of course, you can also set these properties through EMC by selecting the mailbox and then going to the Resource General tab. Figure 6-45 shows the custom property picker that exposes the set of properties defined with the Set-ResourceConfig cmdlet. Because we ve selected a room mailbox, it follows that Exchange has applied a filter so that the picker only displays the custom properties applicable to room mailboxes.

Another important property is shown on the Resource General tab. When you enable the Resource Booking Attendant, you instruct Exchange that the attendant should monitor incoming meeting requests for the room to decide whether or not the requests should be accepted. The policy set for the room mailbox determines the action that the Resource Booking Attendant takes. Each room mailbox can have a distinct booking policy that you can see through the Resource Policy tab. Figure 6-46 illustrates two important property tabs that provide the direction to the Resource Booking Attendant: the Resource Information tab and the Resource Policy tab. The Resource Information tab defines how the attendant handles items that it adds to the calendar of the room mailbox. This information is exposed if a user browses the room s calendar to look for a suitable time to schedule a meeting. Attachments, comments, and subjects for meetings are removed because they often contain confidential information that you don t want all to see if they look for a meeting slot. You can also see that a property governs how noncalendar items are processed when they are delivered to the mailbox. Room mailboxes have SMTP addresses and can be sent normal email like any other mailbox. Telling Exchange to remove noncalendar items as they arrive keeps the mailbox from filling up with unwanted material. The Calendar Assistant can be configured to remove old
