Room Lists in Exchange 2013

Creating room lists in Exchange 2010 has developed over time into a process that is fairly easy to implement and visually see (Recipient Configuration > Distribution Group).  However, Exchange 2013 is not quite there yet.

It is true with both Exchange 2010 and 2013 you have to create a room list via EMS.

With Exchange 2010, a distribution group can be converted to a room list…

     Set-DistributionGroup -Identity “West Coast Office” -RoomList

However, with Exchange 2013 CU1 (using the same command syntax), a distribution list cannot be converted to a room list…

     Set-DistributionGroup -Identity “East Coast Office” -RoomList

This is the error receive in the 2013 EMS…

Group “domain1.local/Test/East Coast Office” can’t be converted to a room list. Room lists can only have room mailboxes or room lists as members.
“domain1.local/Exchange Users/Test-Admin” is not a room mailbox or a room list.
    + CategoryInfo          : NotSpecified: (domain1.local/Test/East Coast Office:ADObjectId) [Set-DistributionGroup], TaskInvalidOperationException
    + FullyQualifiedErrorId : F25FFBB1,Microsoft.Exchange.Management.RecipientTasks.SetDistributionGroup
    + PSComputerName        : d1-ex13-01.domain1.local

In order to create a room list in Exchange 2013, we have to create a new distribution list as a room list from the very beginning.  Using EMS, we should be able to issue a command similar to the following to create our new room list…

     New-DistributionGroup -Name “East Coast Office” -OrganizationalUnit “domain1.local/Test” -RoomList

Upon successful creation, we will see that the request is completed with the details of the new room list displayed (Name, DisplayName, GroupType, PrimarySmtpAddress).

The biggest difference for me between 2010 and 2013, is that in 2010 we can see the room list (in EMC) after it has been created (or converted).  In 2013 CU1, room lists are not displayed in the EAC under Recipients > Groups–and they are nowhere to be found in the EAC.

But there is a way to confirm they have been created.  Use the following command to display all distribution groups and what type they are…

     Get-DistributionGroup | ft -auto Name, RecipientType, RecipientTypeDetails

Once we have confirmed the new room list has been created we can add members to it.

NOTE: We can only add room mailboxes (or other room lists) to room lists or we will receive an error message similar to this…

     “Only room mailbox or room list can be added into room list”

At this point, make sure you have a room mailbox to add to a room list.  Once you have identified your list of room mailboxes that will be added to your room list, use the following command to add room mailboxes as members of the room list…

     Add-DistributionGroupMember -Identity “East Coast Office” -Member ConfRoomA@domainname.com

Use the same syntax to add other room mailboxes to your room list.

Now that we have created a room list and assigned room mailboxes to it, scheduling conference rooms for a specific location should be easy using the Office Outlook client or Exchange 2013 OWA.

On-premise Mail Flow Issue After AD FS Decommission

In my lab last week, I decommissioned AD FS and DirSync to bring Exchange back on-premise after a brief period of co-existence.  The only federated user I had for this environment was no longer able to receive mail in to the on-premise mailbox–however I could send as that user.  The inbound SMTP logs all showed the communication but no successful completion of the connection.

I confirmed the TargetAddress attribute was no longer pointing to the onmicrosoft.com address.

The NDR message received looked like this…

     Delivery has failed to these recipients or distribution lists:

     User

     A problem occurred during the delivery of this message. Microsoft Exchange will not try to redeliver this message for you. Please try resending this message later, or provide the following diagnostic text to your system administrator.

     Diagnostic information for administrators:

     Generating server: exchangeserver.domainname.local

     user@domainname.com

     #< #5.4.6> #SMTP#

The local administrator account also has a mailbox and is able to receive external messages without an issue.  And when I checked this mailbox found NDR messages similar to those just below.  Luckily, I set up the administrator mailbox as the postmaster to be able to see this information…

     The following recipient(s) cannot be reached:

           User on 5/13/2013 11:09 AM

                 A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients.  Contact your administrator.

                 <exchangeserver.domainname.local #5.4.6>

I was able to use the information above to trigger a thought, “Eventhough I removed the reference to onmicrosoft.com, maybe the TargetAddress attribute is still not correct”.

That is when I noticed my mistake, I changed to user@domainname.onmicrosoft.com to user@domainname.com and this is the reason the mailbox would not receive emails–from external and internal senders.  The TargetAddress attribute must be cleared if you want mail to flow properly into an on-premise mailbox.  Any value that is set in this field will attempt to send the message out of the environment even when that email address is local to the environment.  Once the TargetAddress attribute was cleared to <Not Set>, mail flow resumed.
