1️⃣ Overview

We had in the past a documentation with giving the API full access (read & write) to all agendas (User and resources) and limited then the access by using a Mail-enabled security group. If you have this in place, and you had added a new resource, the new resource in the ROOMZ Poral will be red, most of the time you will have an error message with ODATA is disabled.

2️⃣ Add a new resource to the Mail enabled security group

You could add the new room by using PowerShell commands over the ExchangeOnline Module in PowerShell (2.1) or use the graphical interface in the M365 Admin Center (2.2)

2.1 PowerShell

a. Install or start Exchange Online PowerShell Module. You can install the Module directly in the PowerShell on your Computer:

1. Update your PowerShell to the latest version by using the following commands:

   winget install --id Microsoft.Powershell --source winget

   Please note that if you had PowerShell V5 before the new PowerShell V7 will be a new app on your PC, we recommend to use the version 7.x.

2. Now you can install the Module by the following commands:

   Install-Module -Name ExchangeOnlineManagement

   If you get an error message like the following, you have to allow PowerShell to run scripts:

   

   Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine

   After the installation, we recommend to set the policy again to “restricted”:

   Set-ExecutionPolicy -ExecutionPolicy restricted -Scope LocalMachine

3. You need to import the module :

   Import-Module ExchangeOnlineManagement

b. Execute the following command and connect to your Microsoft365 using an admin account.

Connect-ExchangeOnline

1. Fill this group with all room mailboxes. Don't forget to change the name of RoomzResources should you have used another name:

   Get-Mailbox| where {$_.RecipientTypeDetails -eq "RoomMailbox"} | foreach {Add-DistributionGroupMember -Identity RoomzResources -Member $_.UserPrincipalName}

2. Or fill this group with a specific room mailbox. You have to execute the following command and replace myROOM with the E-Mail of your room. Don't forget to change the name of RoomzResources should you have used another name:

   Add-DistributionGroupMember -Identity "Building 32 Conference Rooms" -Member confroom3223@contoso.com

2.2 Graphical user interface

• Login to the Admin Portal of M365 and browse to “active teams and groups” :
  

  

• Select Mail-enabled security and sear for ROOMZ Ressources, click on Members and View all and manage members:
  

  

• You can now click to add members and search for your new resources and add them to the group. (it could take up to 24h until the resource in the ROOMZ Portal is green)
