This is on a Exchange 2013 installation. Is there an official Technet article or white paper that states the amount of conference rooms that are displayed to an OWA client when trying to "Add a room" to a meeting? We currently have over 200+ conference rooms and when clicking on "Ad a room" I only see 100 conference rooms. The view only shows what is available so I try and schedule a meeting on Saturday or Sunday when no one has booked those rooms and I only show 100 meeting rooms. Reading the OWA help states the following:

Enter a location, or select Add a room to see a list of available conference rooms from your organizations address book. Select Scheduling Assistant to show the calendars of attendees. You can also add or remove attendees and automatically schedule resources such as conference rooms.

It does not mention anything regarding the view being limited to 100 conference rooms. I have searched for some sort of documentation that states OWA only shows 100 conference rooms but cannot find anything. Anyone have any ideas as to where I may find this stated somewhere?

Hi,

It is by design. The room list is limited to 100 objects. The recommended way to manage a large number of conference rooms is to create Room Lists and add the room mailboxes to specific room lists.

We can use the New-DistributionGroup cmdlet to create a room list:

New-DistributionGroup -Name "Building 32 Conference Rooms" -OrganizationalUnit "contoso.com/rooms" RoomList

Add rooms to the list:

Add-DistributionGroupMember -Identity "Building 32 Conference Rooms" -Member confroom3223@contoso.com

Add-DistributionGroupMember -Identity "Building 32 Conference Rooms" -Member confroom3224@contoso.com

Then we can click Add a room in OWA to select the room list. The created room list can also be used for room finder feature in Outlook:

Hello Winnie,

Thanks for responding. I don't have a problem with this limitation being by design and I understand how to get around it by creating a room list. I'm looking for actual MS documentation stating this design decision. There are non-technical managers asking why they can't see all of the available conference rooms in OWA. I can tell them the limitation is by design but the problem is I cannot back that up with any sort of documentation. I'm having a hard time finding this information.

Hi,

Sorry that there is no official article about there is a limitation of only 100 availible meeting rooms shown in OWA when making a meeting request. But it is by design. Additionally, when creating room lists in Exchange, there is also a number limitation. A room list has a limit of 100 room mailboxes per room. For more information about it, please refer to the Solution part in the following KB:

This link was worth visiting.

I had a quick question - I understand there is a limit of 100 mailboxes. However, I can only see 2 rooms when I click Add rooms from OWA. I do have more than 100 room mailboxes that are on Exchange Online. How can I make them visible from Add Rooms button without creating Room List ?
