I am trying to create new room distribution list in O365 for my company via PowerShell.

I want to list those rooms in MS Teams so I can book via Teams client

From what I learned, the steps are pretty straightforward

  1. Create new distribution list with room mailboxes as members

New-DistributionGroup -Name "ShRooms" -Members room1@contoso.com,room2contoso.com

  1. Set the group as RoomList

Set-DistributionGroup -Identity "ShRooms" -RoomList

But instead of some positive result, I got this:

A parameter cannot be found that matches parameter name 'RoomList'.
    + CategoryInfo          : InvalidArgument: (:) [Set-DistributionGroup], ParameterBindingException
    + FullyQualifiedErrorId : NamedParameterNotFound,Set-DistributionGroup
    + PSComputerName        : outlook.office365.com

I tried

(GET-Command Set-DistributionGroup).parameters

and got

So this probably means that there really is not -RoomList parameter present, but from what I learned in documentation, it should be (we are running our company O365 in Europe, no special set-up)

Hope somebody can tell me how to change that distribution list. Thx

  • If I connect to Exchange Online using `Connect-EXOPssession`, I see `Set-DistributionGroup` with that parameter available. – AdminOfThings Oct 07 '19 at 14:12
  • @AdminOfThings Sadly, I tried to connect using Connect-EXOPssession, but the parameters did not change – Mythago Oct 09 '19 at 11:49
  • Could you please try to run this command New-Distributiongroup -Name 'Room List Name' -RoomList, Add-DistributionGroupMember -Identity 'Room List Name' -Member RoomName@gmail.com, Get-Content | Add-DistributionGroupMember -Identity 'Room List Name'? – Trinetra-MSFT Oct 11 '19 at 10:57
  • I think you don't have enough permissions. I experienced the same after I logged in under tenant admin(the minimum required permissions definitely lower) it works perfectly :) https://learn.microsoft.com/en-us/exchange/recipients/room-mailboxes?view=exchserver-2019#what-do-you-need-to-know-before-you-begin – Ilya Dec 23 '19 at 11:18
