Conference RoomDisplay (CRD)

Conference RoomDisplay (CRD) is a simple, professional display meant to be used outside conference rooms etc.

This is a inexpensive yet fully functional alternative to GoGet, Evoko Room Manager and others. You run the Windows Store App on an inexpensive 7/8", Windows 8.1/10 tablet (I run it on a $100 Point of view device). For Exchange, It uses Exchange web services so there is no need for any additional Windows/Exchnge CAL. The Windows Store license allows you to use it on up to 10 devices.

Room List Display (RLD)

Room List Display (RLD) is a simple, professional display meant to be used in the lobby to display todays scheduled meetings in the different conference rooms.

This is a inexpensive yet fully functional alternative to GoGet Room Display and others, if you are using Microsoft Exchange to book conference rooms.

You can for example run it on a "pc on a stick" connected directly to the hdmi port of a TV. It uses Exchange web services so there is no need for any additional Windows CAL.

Configuration is the same as for Conference RoomDisplay whith the exeption of:

* Only has support for Exchange/Office365

* You pick a room-list to display instead of a single room.

Personal RoomDisplay

Personal RoomDisplay i essentially the same App as Conference RoomDisplay exept that it displays a private calendar for a regular user.

It is ment to be used as a digital display of your (or the boss) schedule.

Put it up outside your office door.

Configuration is the same as for Conference RoomDisplay whith one big exeption.

* You don't need to configure your Exchange environment.

* No need for any service-account, logon with your normal user.

System Requirements

What you need to run the app.


Start screen

Basic screen showing an available room. If the room is available the colorbar on the left-hand side is green. A button "Book Meeting" to book the room quickly from the display is shown.

Book Meeting

Pressing the "Book Meeting" button will take you to the quick-booking menu.
From this menu you have a few predefined choices for the meeting length which depend on when the next scheduled meeting is.


If Autocancel is enabled, you must press "Start Meeting" within the autocancel timeout-period. Otherwise the meeting will be removed. (This will not show when you Quick-book a meeting). Notice that the colorbar to the left is red when the room is occupied.

Start the upcoming meeting

If the room is available and Autocancel is on, you can start the upcoming meeting up to 15 minutes in advance by pressing "Start Next Now". This is so that if the room is available, you may go in and prepare the meeting without having to go out to press "start meeting" when the meetings actual start time occur.

End Meeting

If the meeting ends earlier than expected, you press "End Meeting Now" when leaving the room to free up the resource and make the room available.

Calendar Booking

If enabled, you can book upcomming meetings with the caledar icon in the top right corner. Note that this will only book the room, it will not show in your own calendar


Before you begin

Before you can start using your Conference RoomDisplay you must first set up your Calendar Service provider, eg Exchange/Office365 or Google.


First you need an Exchange account.
You can basicly use any existing account, but this account must have impersonate privileges of the room-recource mailbox so the prefered way would be to have a separate "service account" set up for the Conference RoomDisplays. 

Once your Exchange environment is set up you can start the Conference RoomDisplay app an configure it.

Google Calendar

You can use any Google account and you can use any calendar that this user have at least write permissions on, created on or shared with that account.

CRD Configuration

When you first start the App it will show the Account Settings. 

Subsequent changes 

On Windows 8, swipe from the right, chose settings and then Account settings. On Windows 10 you find the settings menu on the top menu bar.

Service Provider

Simply select which Calendar Service provider you are going to use.



For office 365 This URL is usually:

For on-premise Exchange This URL is usually the same url that you use to access Outlook Web Access (OWA) with the  "/EWS/Exchange.asmx" added at the end e.g: https://owa.yourdomain.com/EWS/Exchange.asmx

User credentials

Username In the UPN form e.g. CRD-Service-Account@ad.yourdomain.com 

Password Is obviously the password for the account used 

Authentication Type  (as from version this field is removed, no longer needed/) For Office365 this should be set to Basic For on-premise this is normally NTLM (kerberos)

Room e-mail & Display name

Room Email Enter the e-mail address to the room you want to display 

Displayname Enter the name for the room. 

This is not fetched from the room mailbox displayname since these tend to be long and cryptic names.

Test Connection

After you filled in all information, hit "Test Connection" to validate that you can access the Exchange/Office365 room resource and that you have all the permission needed. 

If everything is okay, you should se a "checkmark" to the right. 

"X" indicates an error and a questionmark "?" means that a validation error occurred before this could be tested. 

Username, password and Authentication type will all have "X" if there is an authentication error (even though only one might be wrong)


After selecting Google as your calendar serice provider you first select Authorize


Hitting Authorization will take you to the google login form.

Sign in and allow Conference RoomDisplay to manage your calendar


Hit "Re-Authorize" to select a new/different google account.

Select Calendar

After you compleded the authorization process, you need to go back to the Account Setting and specify wich calendar to use. 

By default, after initial authorization, the primary calendar associated with the google account is selected. 

Note You can only use calendar on which you have at least permission to "Make changes to events".  This is true even if you don´t allow booking directly from the display. You don´t however, need the be the calendar "owner". You can set up a specific account to use on all your displays, share calendars to that account (with the above permissions), and then select which calendar to use.


Set Active Days/Time

This acts like kind of a screensaver since you don´t want to use the windows built-in screensaver (see Windows 8/10 setup). You can specify on which days and during which time during these days that the display should be active.
Outside these settings the screen goes completly black if nothing is booked. 30 minutes before an upcomming event the display will still  activate and stay active during the event.  


Logo Select a logo to be displayd in the top left corner. The image is resized to 150x150px.  

Background Select a backgruond picture for the display. Picture will be stretched. 

X X Button to the right will remove Logo/Background picture.

Calendar booking

If this toggle is on, an icon that allows calendar booking directly from the display is shown in the top right corner. 

Consider the following before enabling:
When a calendar booking is made from the display, it is made from the "CRD-service-account" useraccount. This means that the user will not normally be able to change or delete this booking afterwards (from their own Outlook or Google calendar). 

Also the organizer will show the Rooms name.

Allow Quick Booking

This will enable/disable the "Book Meeting" feature, directly from the display, if the room is availabe. 

In a public environmen you might not want to have this feature enabled. 

Note: To compleatly disable the possability the book the room directly from the display, you must also disable "Caledar booking"


Enabling Autocancel will have the following effect.  

  • You must press "Start Now" on the display when you enter the room to actively start the meeting. Otherwise the meeting will automatically be removed after the autocancel timeout has expired.
  • If the room is available, you will be able to start the meeting up to 15 minutes prior to the actual start time from the display by pressing "Start Next Now". 

PIN code

You can PIN-code protect Account settings and Customization menu. In a public environment you might not want everyone to be able to acces and customize the display. 

Default PIN when you first enable this feature, the PIN is set to  1234. 

After the display is unlocked, it will be accessable for 2 minutes without entering the PIN everytime you access the menu.

PBX prefix

A special case where some outlook PBX/auto-attndant will let you control the auto-attendant by specifying a three letter prefix followed by a (:) in the subject line of a meeting. (e.i. MET: My meeting). 

If you set this switch to "Hide PBX prefix" any three letters followed by a (:) will be skipped. So in the above example the display would show "My meeting". 

Exchange configuration

On the Exchange server you need to create a service account that the Conference RoomDisplay uses to be able to make Quick-bookings, end meeting early, auto-cancel meetings etc. If you are not the Exchange administrator of your domain please consult with her/him before going any further. The service account needs:  

  1. "Full Access" to the room-resource calendar
  2. "Application Impersonation" privileges 

The following powershell commands shows an example on how to set impersonate privileges in an office365 environment for a account named "RoomDisplayServiceAccount"

Connect to office365

PS>$UserCredential = Get-Credential 

PS>$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic –AllowRedirection 

PS>Import-PSSession $Session

Create a new management scope

The following will create a scope named "Room Mailboxes" that applies to all Room Mailboxes in your organization 

PS>New-ManagementScope -Name "Room Mailboxes" -RecipientRestrictionFilter {RecipientTypeDetails -eq "RoomMailbox"}

The following will create a scope named "Room Mailboxes at OrgUnit" that applies to all Room Mailboxes within a specific organizationalUnit

PS>New-ManagementScope -Name "Room Mailboxes" -RecipientRoot "ad.yourdomain.com/orgunit" -RecipientRestrictionFilter {RecipientTypeDetails -eq "RoomMailbox"}

Assign the ApplicationImpersonation Role

The following assigns the needed ApplicationImpersonation role for the user "RoomDisplayServiceAccount" within the scope "Room Mailboxes" created above.

PS>New-ManagementRoleAssignment –Name "ConferenceRoomDisplay" -Role:ApplicationImpersonation –User "RoomDisplayServiceAccount" –CustomRecipientWriteScope "Room Mailboxes"

Change default behavior of room mailbox

As default, Exchange will substitute the Subject with the Organizer when you send a meeting request to a room mailbox. This is often an unwanted behavior.

Use the following command to prevent this from happening. 

PS>Set-CalendarProcessing -Identity "Your Room mailbox Name" -DeleteSubject $false -AddOrganizerToSubject $false

Google Configuration

You realy only need a google account for this to work... 

I'm not going to go into details on how to set up google calendars (google it) but if you intend to use it like a room-resource (the same way as a outlook/exchange room) you need to configure the calendar to auto accept invitations.

Windows 8/10 setup

These are my personal recomentations on how to set up windows with this app. You don't want screensaver, automatic updates, messages etc. messing up the display or schedule reboots. What I do to avoid this is:  

  • Disable screensaver
  • Under energy options, make sure that screen in never turned off.
  • Also disable powersave mode
  • Disable all notifications under System > Notifications & actions
  • Turn off automatic Windows Update.
    In Windows Home, there is a "workaround" for this. On the Settings > WiFi tab, click advanced settings and mark the connection as "Metered connection".
  • In Windows Store, goto settings and disable automatic update of store apps
  • On Settings > Ease of Access > Keyboard.
    Enable Filter Keys, then turn off all but enable "Bounce Keys" and set it to 10sec. This will prevent someone accidental hitting the hardware windows-key.

  To have the App autostart, follow these steps.  

  • Open the File Explorer
  • In the file address bar type shell:AppsFolder
    (this will show all installed apps)
  • Right-click and create a desktop shortcut
  • Right-click on the shortcut, properties and select Run: Maximized
  • Now type shell:startup in the address bar
  • Copy the shortcut to this folder

System requirements



  • Exchange server 2010+ or Office365
  • Service account with impersonate privileges and full access rights on room-resource mailboxes
  • At least one room-resource mailbox.


  • A google account.


  • Windows 8.1 or Windows 10 (touch device)

  • Disable screensaver and powersavings.
