Getting Started Guide for Office 365

Setting up your first meeting rooms for Office 365

This guide sets up meeting room displays for Office 365 (Microsoft 365) in 3 steps:

1. Create a room mailbox in Microsoft 365.
2. Create the display in Meeting Room 365.
3. Set up the tablet in the room.

Step 1 happens in the Microsoft 365 admin center. If another IT admin manages your Microsoft 365 tenant, ask that person to do step 1.

Step 1: Create a room mailbox in Microsoft 365

Each meeting room needs its own room mailbox (Microsoft also calls it a resource mailbox). The room mailbox gives the room an email address and a calendar. It accepts meeting invites for the room.

1. Sign in to the Microsoft 365 admin center.
2. Select Resources, then Rooms & equipment.
3. Add a room mailbox for each meeting room.

For every screen of this step, follow How to Add a Meeting Room to Outlook or Office 365 for Free.

If you will sign in to each room mailbox directly in step 2, the room mailbox needs a password. Reset its password in the admin center, the same way you reset the password for any other user.

Step 2: Create the display in Meeting Room 365

1. Sign in to the Meeting Room 365 Admin Portal.
2. In the menu, select New Display, then Meeting Room.
3. Select Microsoft 365.
4. Choose how to connect (see below).
5. Copy the Display Key that the portal gives you. You enter it on the tablet in step 3.

The portal gives you 3 ways to connect:

• Connect to Calendar Directly. Enter the room mailbox email address, then sign in to Microsoft 365 as the room mailbox. Use this for a small number of displays, one at a time.
• Set up a Service User Account. One user account connects all of your room mailboxes. You give the service user access to the room mailboxes in Microsoft Entra ID. See Use a Service User instead of Direct Sign in (Office 365).
• Client Consent (RBAC). An admin grants consent in Microsoft Entra ID, and you set up many displays without a user account. See Role-Based Access Control via PowerShell (Microsoft 365).

Microsoft recommends that you block sign-in to room mailboxes. If your tenant blocks it, direct sign-in fails. Use a service user or Client Consent instead.

Step 3: Set up the tablet in the room

1. Install the Meeting Room 365 app on the tablet from the Apple App Store, Google Play or the Amazon Appstore.
2. Open the app and select Enter Display Key.
3. Enter your Display Key.
