How suite booking works

Users open a meeting invite in Outlook, click the DivisibleRooms task pane, and see available suites for the selected date and time. Select a suite, and the system handles everything else.

What DivisibleRooms handles automatically

  • Availability check across all rooms in a suite, before it's surfaced as bookable
  • Writing room bookings to the invite when a suite is selected
  • Placing transition window blocker appointments to protect reconfiguration time
  • Updating or removing blockers when a meeting is rescheduled or cancelled
  • Reconciling orphaned blockers on a background cycle

Why it's different

Exchange-native, not Exchange-synced

DivisibleRooms writes directly to Exchange. Competitors that don't write natively require a named Exchange Connector or an external sync process. Native writes mean no sync lag, no connector dependency, no additional Exchange configuration.

Works with Microsoft Teams Rooms

Because bookings are written natively to Exchange room mailboxes, Teams Rooms panels on each physical room display suite bookings and transition windows correctly, with no additional configuration. This is a consequence of the architecture, not a separate integration.

Pure Outlook experience

The add-in appears in the Outlook compose window and disappears when not needed. No separate booking portal, no new login, no interface to learn. Individual room booking continues through Outlook as always.

Multi-tenant, fully isolated

One deployed instance serves every customer, with full tenant isolation. Each organization's data, credentials, and configuration stay separate at every layer, from authentication down to the database.

Built for the team that manages the rooms day to day

Once DivisibleRooms is set up, your IT team steps back. From day to day, it's your facilities or admin-services team who lives in the tools below.

DivisibleRooms Dashboard

See every suite booking and transition window in the DivisibleRooms Dashboard, built for daily use, not deep configuration.

DivisibleRooms Report

A scheduled email, with a CSV export, showing booking activity, transition window compliance, and usage patterns over time.

Set the report's recipients, frequency, and timezone once during setup. No manual tracking or spreadsheets needed to stay on top of suite usage.

Security and permissions

DivisibleRooms is a multi-tenant SaaS application using application-level Microsoft Graph permissions, with full tenant isolation at every layer. Full technical and security documentation, including the IT Security One-Pager and architecture details, is available to qualified evaluators on request.
