您好，
建议您再次确认在Exchange添加room list的基本步骤：
1.
在Exchange Server上新建room list的DL（distribution list），使用命令：
New-DistributionGroup -Name <String> –RoomList
详细的参数说明可以参考“New-DistributionGroup“：
https://technet.microsoft.com/en-us/library/aa998856(v=exchg.141).aspx
2.
把room添加到DL，使用命令：
Add-DistributionGroupMember –Identity "Name of Room List" –Member "Name of Room Mailbox"
详细的参数说明可以参考“Add-DistributionGroupMember”：
https://technet.microsoft.com/en-us/library/bb124340(v=exchg.141).aspx
此外，可以通过以下命令列出Room List Distribution Groups:
Get-DistributionGroup | Where {$_.RecipientTypeDetails -eq "RoomList"} | Format-Table DisplayName,Identity,PrimarySmtpAddress
通过以下命令列出已有的Room Mailboxes:
Get-Mailbox | Where-Object {$_.RecipientTypeDetails -eq "RoomMailbox"} | Format-Table DisplayName,Identity,PrimarySmtpAddress
确认以上步骤已经完成后，建议再次打开Outlook客户端，再确认情况如何。如果问题依旧，建议您访问Exchange Server论坛提问：
