使用PowerShell脚本来轮训Exchange数据库的状态

这是来博客园的第一篇文章...当然...我在很多地方贴过这篇文章..如果你在其他地方看过，请不要介意。

常识性的，我会给出这篇文章“真正”的原创作者，博主的博客中有更多和Exchange以及PowerShell相关的内容，如果你感兴趣，将非常能吸引你。

Write-Host "开始之前，需要指定邮箱服务器位置，例如：exchangeserver.contoso.com" 
$exserverName = Read-Host; 
#发送远程指令，下载Exchange"管理程序集"
$psUri = "http://$exserverName/powershell"; 
$usecredential = Get-Credential

# 发送邮件 Write-Host "开始尝试发送警告邮件..."

#保留这段代码，因为它的输出方式值得学习

"已经发送邮件至 $messageTo"; 
}

#这是先前使用powershell发送邮件的做法 
#Send-MailMessage -From "owmaster@ouwei.cn" -To "$messageTo" -Subject"Alert From ExchangeServer Named $exserverName"

#之所以这种方式开始的时候行不通，是因为没有提供用户凭据 
#可以使用Get-Credential获取一个凭据，然后作为参数在Send-MailMessage指令中使用

 PowerShell和Exchange管理和C#和.NET放在一起将会是非常有趣的东西，我会整理更多的内容，所以暂时原谅我偷懒照搬吧。同时希望能在这里交到朋友，一起讨论，共同进步。
