问题描述：
==================
某客户Exchange 2010服务器硬件硬障造成系统重装，只留下原有Exchange的数据为文件，希望能从旧的数据库中找回用户邮箱数据。当尝试使用恢复数据加载旧的数据库文件时，出现下面的报错信息;
日志名称: Application
来源: MSExchangeIS
日期: 2012/5/2 17:33:19
事件 ID: 1088
任务类别: 常规
级别: 错误
关键字: 经典
用户: 暂缺
计算机: mail.abc.com
描述:
无法启动该数据库，因为邮箱数据库“rdb”的可分辨名称(DN) /O=abc/OU=EXCHANGE ADMINISTRATIVE GROUP (FYDIBOHF23SPDLT)/CN=RECIPIENTS/CN= 与目录 /O=aibici/OU=EXCHANGE ADMINISTRATIVE GROUP (FYDIBOHF23SPDLT)/CN=RECIPIENTS/CN= 的 DN 不匹配。
该数据库可能已还原到组织或站点中的某台计算机上，而没有还原到原始数据库中。
原因分析:
==================
根据与客户沟通发现。原来全新安装Exchange造成的 legacyExchangeDN 属性值旧的Exchane 在 Active Directory 中存储的属性值不同而无法装入。
解决方案：
==================
需要使用ADSIEdit等工具修改legacyExchangeDN 属性值。
