需要在Powershell脚本中添加“等待”命令

这是我当前的代码：

Write-output “ENTER THE FOLLOWING DETAILS - When Creating Multiple New Accounts Go to           EMC hit F5(refresh) and make sure previous new account is listed before proceeding to the       next one”
$DName = Read-Host “User Diplay Name(New User)"
$RUser = Read-Host "Replicate User(Database Grab)"
$RData = ((Get-Mailbox -Identity $RUser).Database).DistinguishedName
$REmailInput = Read-Host “Requester's Name(Notification Email goes to this Person)"
$REmail = ((Get-Mailbox -Identity "$REmailInput").PrimarySmtpAddress).ToString()

Enable-Mailbox -Identity "$DName" -Database "$RData" 
Set-CASMailbox -Identity "$DName" -ActiveSyncEnabled $false -ImapEnabled $false -    PopEnabled $false


Send-MailMessage -From "John Doe <John.Doe@xyz.com>" -To $REmail -Subject       "$DName's email account" -Body "$DName's email account has been setup.`n`n`nJohn Doe`nXYZ`nSystems Administrator`nOffice: 123.456.7890`nJohn.Doe@xyz.com" -SmtpServer exchange@xyz.com

这段代码完美地工作了大约一半的时间，但是另一半我得到了以下错误：

ENTER THE FOLLOWING DETAILS - When Creating Multiple New Accounts Go to EMC hit
F5(refresh) and make sure previous new account is listed before proceeding to
the next one
User Diplay Name(New User): Jane Doe
Replicate User(Database Grab): Julie Doe

因此，如果有人可以在创建邮箱后帮助我发出某种等待命令，并等到用户的邮箱创建之后再脚本禁用ActiveSync等，这将非常有用。我相信，仅使用-wait开关是行不通的。

使用Start-Sleep命令：

Start-Sleep -s 10

将暂停脚本10秒钟。

我不得不在前一段时间编写的Exchange脚本中处理一些时间安排。具体来说，我需要修改对新创建的通讯组的权限，但需要等到实际创建通讯组后才能尝试对其进行修改。

do {
    sleep -seconds 1
    $mailboxExists = get-mailboxpermission -Identity "CN=$displayName,$DN" -User "NT AUTHORITY\SELF" -ErrorAction SilentlyContinue |fw IsValid
    write-host "." -nonewline
} while (!$mailboxExists)

它只是尝试从邮箱（在本示例中）中获取“ IsValid”属性，作为“邮箱存在”的代理。一旦get-mailboxpermission返回true，下一步实际上就是设置权限。该write-host仅仅是提供一个进度条。

您可以将其作为后台作业运行，然后等待该作业完成。像这样：

$ enablemb =开始作业{启用邮箱-身份“ $ DName”-数据库“ $ RData”}
等待作业$ enablemb
接收作业$ enablemb

开始睡眠=等待x秒

为什么不这样：

do {
$testpath = Test-Path -path \\dns2\d$\test
}
until ($testpath -eq $true)

start-sleep在初始测试之后，我将这种类型的命令与其他命令一起使用，因为在没有它之前，它会吃掉很多处理器周期。所以我的看起来更像这样：

do {
$testpath = Test-Path -path \\dns2\d$\test
start-sleep -s 10}
until ($testpath -eq $true)

如果测试即将迅速改变状态，则不必担心start-sleep。
