How to Fix: Outlook Room Finder empty in Microsoft 365

Описание: Outlook Room Finder not showing any rooms? Here’s why: Microsoft 365 doesn’t set this up for you. There’s no automatic option in the admin portal to create or organize rooms into Room Lists—you have to do it manually in PowerShell.

Step 1: Connect to Exchange Online PowerShell
Step 2: Create a Room List
New-DistributionGroup RoomListName -RoomList -Members $Members
Step 3: Add rooms to the list

Add-DistributionGroupMember RoomListName -Member RoomMailbox
Step 4: Verify rooms are visible in the Global Address List
Get-Mailbox RoomSMTPAddress
Confirm HiddenFromAddressListsEnabled is set to False

After that, Room Finder will start showing those rooms once directory changes sync, usually within 24 hours. It’s not broken—Room Finder just needs Room Lists created and populated via PowerShell before users will see anything.
