解决途径：
先看下问题出在哪，PS下运行命令Get-OrganizationConfig，运行部分结果如下：
[PS] C:Windowssystem32>Get-OrganizationConfig
RunspaceId : 2ab8772c-967d-4a08-a296-30c5a6257fd1
Name : First Organization
LegacyExchangeDN : /o=First Organization
Heuristics : None
JournalingReportNdrTo :
ResourceAddressLists : {test.local/Configuration/Deleted Objects/所有会议室
DEL:a29e5736-92e0-4cd1-ac8a-05d662091de5}
IsMixedMode : False
IsAddressListPagingEnabled : True
红色标示属性ResourceAddressLists链接了一个已删除的对象。。。接下来就是修改adsiedit中属性的问题了。
1.重新创建名为“所有会议室”的地址列表，UI下搞不了，命令行更方便：
[PS] C:Windowssystem32>New-AddressList -Name 所有会议室 -RecipientFilter {(Alias -ne $null -and (RecipientDisplayType
-eq 'ConferenceRoomMailbox' -or RecipientDisplayType -eq 'SyncedConferenceRoomMailbox'))}
2.adsiedit.msc
CN=FirstOrganization,CN=MicrosoftExchange,CN=Services,CN=Configuration,DC=test,DC=local，右键属性，找到msExchResourceAddressLists，将其值修改为：
CN=所有会议室,CN=All Address Lists,CN=Address Lists Container,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=test,DC=local <步骤1中新创建的所有会议室地址列表>
3.重启下“Microsoft Exchange 通讯簿”服务。
