Default Calendar Permissions for Resources

By default, when you use the wizard to set up a room resource mailbox, you can only see the availability in when actually making a booking.
Often, users like to get an overview of the mailbox by opening the Calendar for that mailbox, but Exchange 2010 doesn't set that up.

To assign the permission of "Reviewer" to Everyone (aka Default), just enter this command in Powershell

Set-MailboxFolderPermission <alias>:\Calendar -User Default -AccessRights Reviewer

You can check that the change has taken effect with

[PS] C:\>Get-MailboxFolderPermission <alias>:\Calendar

RunspaceId   : 8123cde4-1ca5-3459-9b36-a46fcc01a22a
FolderName   : Calendar
User         : Default
AccessRights : {Reviewer}
Identity     : Default
IsValid      : True

RunspaceId   : 8123cde4-1ca5-3459-9b36-a46fcc01a22a
