What Room Finder needs

Four steps from empty to organized.

Room Finder helps people locate available meeting rooms and workspaces, but only once each space has a mailbox and is grouped into a Room List. Here's the path the script automates for you.

STEP 01

Create Resources

Provision a room or workspace mailbox for every space your team can book.

STEP 02

Create Room Lists

Build the distribution groups Room Finder reads, one per building or location.

STEP 03

Add Rooms to Lists

Assign each resource mailbox to the Room List for its building.

STEP 04

Set Place Properties

Tag rooms with location, building & capacity so Room Finder filters work.

Each Room List is a Microsoft 365 distribution group that contains the resource mailboxes for each space. We recommend organizing every building into its own logical group for easier management in Room Finder.

Why PowerShell

Microsoft 365 requires setup in PowerShell.

Resources can be created in the Exchange Admin Center, but Room Lists can't, because there's no web interface to finish the job. Room Finder won't show rooms by location until those lists exist.

Is your Room Finder empty, even though you've already set up meeting rooms in Outlook?

That's the missing Room Lists. Run the interactive script, or follow the manual guide, to create them and watch your rooms appear.
