如果收件人地址重复, 发件会收到一封错误NDR, 标明邮件地址重复无法发送, 这里我们需要做如下操作:

 

错误描述如下:

Delivery has failed to these recipients or distribution lists:

 

Yuuki Kitazoe
There is a problem with the recipient's e-mail system. More than one user has this e-mail address. The recipient's system administrator will have to fix this. Microsoft Exchange will not try to redeliver this message for you. Please provide the following diagnostic text to your system administrator and then try resending the message after the problem has been resolved.

 

但我们通过console台查找, 拥有此地址的用户只有一个, 那为什么还是会显示冲突问题?

 

这是因为Exchange2007 Console台查找, 默认为本地域, 如果当前用户在森林的另一个域中, 则显示不出来,需要在console台查找界面的Scope, 选择Forest才可以.

 

当然我们可以通过powershell做处理

 

 

第一步 查询扩展到森林

$AdminSessionADSettings.ViewEntireForest=$true

 

第二步根据邮件账户类型, 查找信息; 我这里是mail contact

Get-MailContact “Shinichi Tonomura”

 

第三步找到重复数据后, 删除

Remove-MailContact -Identity "Shinichi Tonomura"

 

如果有权限删除成功; 如果没有权限会删除失败; 联系管理员进行删除
