Description

This scripts creates a new room mailbox and security two groups for full mailbox access and and for send-as delegation. The security groups are created using a configurable naming convention. If required by your Active Directory team, you can add group prefixes or department abbreviations as well.

The script uses a Xml configuration file to simplify changes for variables unique for your environment.

High level steps executes by the script:

Create a new room mailbox
Create a new mail enabled security group for full access delegation
Assign full access security group for full access to the room mailbox
Create a new mail enabled security group for send-as delegation
Assign send-as permissions to send-as security group
Create a new mail enabled security group for allowed user to book the new room mailbox
Set calendar processing to AutoAccept, if required
Set resource capacity, if rewuired

Examples

Xml settings file

Note

The calendar booking security group feature is currently not available. But will be available in an upcoming release.

The following example creates a room mailbox for an Conference Room with empty security groups.

.\New-RoomMailbox.ps1 
  -RoomMailboxName "MB - Conference Room" 
  -RoomMailboxDisplayName "Board Conference Room" 
  -RoomMailboxAlias "MB-ConferenceRoom" 
  -RoomMailboxSmtpAddress "ConferenceRoom@mcsmemail.de" 
  -DepartmentPrefix "C"

You can simplify the use of the script by using a paramterized helper script named Run-NewRoomMailbox.ps1.

The following Run-NewRoomMailbox.ps1 script simplifies the process of creating a team mailbox even more.

$roomMailboxName = 'MB-Conference Room'
$roomMailboxDisplayName = 'Board Conference Room'
$roomMailboxAlias = 'MB-ConferenceRoom'
$roomMailboxSmtpAddress = 'ConferenceRoom@mcsmemail.de'
$departmentPrefix = 'C'
$groupFullAccessMembers = @('JohnDoe','JaneDoe')  # Empty = @()
$groupSendAsMembers = @()
$groupCalendarBookingMembers = @()
$RoomCapacity = 0
$RoomList = 'AllRoomsHQ'
$Language = 'en-GB'


.\New-RoomMailbox.ps1 
  -RoomMailboxName $roomMailboxName 
  -RoomMailboxDisplayName $roomMailboxDisplayName 
  -RoomMailboxAlias $roomMailboxAlias 
  -RoomMailboxSmtpAddress $roomMailboxSmtpAddress 
  -DepartmentPrefix $departmentPrefix 
  -GroupFullAccessMembers $groupFullAccessMembers 
  -GroupSendAsMembers $groupSendAsMembers
  -RoomCapacity $RoomCapacity 
  -AutoAccept 
  -RoomList $RoomList
  -Language $Language
