Office 365 Meeting Room Displays
Your meeting rooms already live in Microsoft 365 — room mailboxes in Exchange Online, bookings in Outlook. Meeting Room 365 room displays put that calendar on a tablet outside each door so anyone can see availability and book without opening their laptop.
When someone instant-reserves or ends early on the display, the change writes to the same room calendar your organization already uses.
The scenario
| You have… | You want… |
|---|---|
| Microsoft 365 room resources | Live available / busy state outside each room |
| Ghost bookings and no-shows | Force check-in, extend, and end early from the door |
| Workplace branding | Logos, themes, and languages on every display |
| Maybe video-heavy conference rooms | Optional Meeting Room TV inside + status board in the lobby |
Pricing: $9/month or $99/year per licensed meeting room. Status boards and most customization are included — no per-display SKU for themes. See Pricing and billing.
What you need in Microsoft 365
- A room mailbox (or equipment mailbox) for each space you want on a display.
- A connection method that fits your scale and MFA policy (below).
- A display in admin.meetingroom365.com linked to that mailbox.
- A tablet or browser running the Meeting Room 365 kiosk app or display URL with your display key.

Choosing a connection method
| Method | Best for | Plain language |
|---|---|---|
| Direct sign-in | Small pilots (few rooms) | Each tablet signs in to its own room mailbox |
| Service user | Centralized IT, many rooms | One trusted account accesses many room calendars |
| Application RBAC / client credentials | Scale without MFA on every resource mailbox | Entra app + PowerShell RBAC scoped to resource mailboxes — Microsoft's recommended pattern at volume |
MFA and resource mailboxes (important)
Microsoft now expects MFA for every account in the tenant, including resource mailboxes. Direct sign-in to ten room mailboxes means an MFA strategy for ten resource accounts — workable for a handful of rooms, often impractical at campus scale.
Most larger rollouts use a service user or application RBAC so IT is not approving Authenticator prompts on room accounts all day. Plan this before you commit to direct sign-in across a floor.
Meeting Room 365 requests minimal permissions — calendar read/write for the linked mailbox, not broad tenant admin. See What permissions does Meeting Room 365 need for Office 365?.
