Moderated Calendar in Exchange 2010 (Using a Resource Mailbox for calendars)

  • Room1 is the room that needs to be moderated
  • MailUser2010 and MailUser2007 are the users that need to have authorization to approve and view the meeting requests

Create a Moderated Resource Calendar mailbox in 3 easy steps

  1. Open Exchange Management Shell
  2. New-Mailbox -Name ‘room1‘ -Alias ‘room1’ -UserPrincipalName ‘room1@MyDomain.Com’ -SamAccountName ‘room1’ -FirstName ‘room1’ –Room
  3. set-CalendarProcessing -Identity "Room1" –AutomateProcessing AutoAccept –ResourceDelegates “MailUser2010”,”MailUser2007” -AllBookInPolicy $false -AllRequestInPolicy $true

You can make further adjustments with: set-CalendarProcessing -Identity "Room1” or use the Exchange Management Console (EMC) and modify the properties of the mailbox you just created (Specifically the “Policy” Tabs)
And you can view settings with Get-CalendarProcessing -Identity "

You can now add the calendar to view and approve in OWA and two users are now able to authorize room access.

To View the new Calendar

  1. Open OWA as a user that you have given delegate access
  2. Click on Calendar
  3. Click Share, then Add Calendar

Retention Policy on Calendar Items in Exchange 2010

As we all know by now, you can no longer use Retention Policy and Retention Tags on Calendar items in Exchange 2010.  So, how would you clean up user’s old Calendar items? Managed Folder saves the day!

Here are the powershell commands to create ManagedFolder and policy:

New-ManagedFolder -Name ‘DefaultCalendar’ -DefaultFolderType Calendar -MustDisplayComment $false

New-ManagedContentSettings -FolderName DefaultCalendar -MessageClass IPM.Appointment -Name DefaultCalendarContentSettings -RetentionEnabled $true -RetentionAction MoveToDeletedItems -AgeLimitForRetention “1”

New-ManagedFolderMailboxPolicy -Name “DefaultCalendarPolicy” -ManagedFolderLinks DefaultCalendar

Set-mailbox -identity johndoe -ManagedFolderMailboxPolicy “DefaultCalendarPolicy”

Start-ManagedFolderAssistant -Identity Johndoe

The most important part is IPM.Appointment. I’ve tried other suggestions from technet such as “Calendar”, but this is the only one that works. 

Note, -AgeLimitForRetention “1” means one day. So the policy should move any Calendar items older than 1 day from your Calendar to Deleted Items folder.
