数据库探寻使用PowerShell从服务器获取数据库信息，一般需要检查Exchange服务器上是否存在如下键值，如果没有的话需要手动添加：
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapIns\Microsoft.Exchange.Management.Powershell.Support]
"CustomPSSnapInType"="Microsoft.Exchange.Management.Powershell.Support.SupportPSSnapIn"
"ApplicationBase"="C:\\Program Files\\Microsoft\\Exchange Server\\V14\\bin"
"AssemblyName"="Microsoft.Exchange.Management.Powershell.Support, Version=14.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
"Description"="Support Tasks for the Exchange Server"
"ModuleName"="C:\\Program Files\\Microsoft\\Exchange Server\\V14\\bin\\Microsoft.Exchange.Management.Powershell.Support.dll"
"PowerShellVersion"="1.0"
"Vendor"="Microsoft Corporation"
"Version"="14.0.0.0"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapIns\Microsoft.Exchange.Management.PowerShell.E2010]
"CustomPSSnapInType"="Microsoft.Exchange.Management.PowerShell.AdminPSSnapIn"
"ApplicationBase"="C:\\Program Files\\Microsoft\\Exchange Server\\V14\\bin"
"AssemblyName"="Microsoft.Exchange.PowerShell.Configuration, Version=14.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
