Change a resource mailbox booking window in Exchange 2010

This is a follow-up on my post on the same topic for Exchange 2007. This post will explain how to change the Booking Windows for a resource mailbox in Exchange Server 2010. This value is set to 180 days by default and many organizations find this a bit low.

In Exchange Server 2010 we use the following command to change this setting:
Set-CalendarProcessing "<ResourceMailboxName>" -BookingWindowInDays <NumberOfDays>

Example:
Set-CalendarProcessing "test3" -BookingWindowInDays 365

If you want to set this for all room mailboxes at once use the following command:
Get-Mailbox | Where {$_.RecipientTypeDetails -eq "RoomMailbox"} | Set-CalendarProcessing -BookingWindowInDays 365

You can verify the settings using the following commands:
Get-CalendarProcessing "test3" | FL Identity,BookingWindowInDays

For all room mailboxes:
Get-Mailbox | Where {$_.RecipientTypeDetails -eq "RoomMailbox"} | Get-CalendarProcessing | FL Identity,BookingWindowInDays

Manage resource work hours in Exchange Server 2007 and 2010

In this post I will show you how to configure the way Exchange handles work hours for a resource mailbox.

Exchange 2007

To set the work hours you can use OWA or Outlook.

OWA
You can find the settings under Options and Calendar Options. Edit the Start Time and End Time of Calendar Work Week.

For OWA client, the Working hours configuration is saved in a hide message in Calendar folder, you can use MFCMapi to check the configuration:

1. Run MFCMapi tool and logon the user mailbox (Online Mode)
2. Open mailbox and expand Root Container and Top of Information Store
3. Right click the Calendar folder and click Open Associated Contents Table
4. Click the message which subject is IPM.Configuration.WorkHours
5. Open the property 0x7C080102 which contains the Work Hours setting.

Outlook
You can either configure the settings using the Outlook client, in Outlook 2010 the settings are in Outlook Options, Calendar and Work Time. Also, the Working hours configuration is saved in following registry key on the client:

HKCU\Software\Microsoft\Office\12.0\Outlook\Options\Calendar
CalDefEnd
CalDefStart

When the work hours are set, you will have to run the following command to make sure that the mailbox only accept bookings during work hours:
Set-MailboxCalendarSettings -Identity <mailboxidentity> -ScheduleOnlyDuringWorkHours $true

Example:
Set-MailboxCalendarSettings -Identity test3 -ScheduleOnlyDuringWorkHours $true

Exchange 2010

In Exchange Server 2010 it’s a bit different. First, this is how you configure the actual work hours:
Set-MailboxCalendarConfiguration -Identity <mailboxidentity> -WorkingHoursStartTime <start time in format 00:00:00> -WorkingHoursEndTime <end time in format 00:00:00>

Example:
Set-MailboxCalendarConfiguration -Identity test3 -WorkingHoursStartTime 08:30:00 -WorkingHoursEndTime 17:30:00

And if you want to change the settings for all room mailboxes:
Get-Mailbox | Where {$_.RecipientTypeDetails -eq "RoomMailbox"} | Set-MailboxCalendarConfiguration -WorkingHoursStartTime 08:30:00 -WorkingHoursEndTime 17:30:00

There are plenty more settings that you can configure, to check the current settings use the following:
Get-Set-MailboxCalendarConfiguration -Identity <mailboxidentity> | fl

When this is done you will have to set the resource mailbox to accept bookings only during work hours:
Set-CalendarProcessing -Identity <mailboxidentity> -ScheduleOnlyDuringWorkHours $true

Example:
Set-CalendarProcessing -Identity test3 -ScheduleOnlyDuringWorkHours $true
