Exchange PowerShell 从输入文件导出邮箱时出错

Question

我正在处理以下 PowerShell 脚本以允许从 .CSV 文件输入以允许批量导出为 .PST

脚本如下：

$Server = 'PRDFS01-VM'
$ServerBackupUNCPath = "\\$Server\PST"
$InputCSVPath = 'C:\SCRIPT\Input.csv'
$ExportExistsCSVPath = 'C:\SCRIPT\Exist.csv'

Import-PSSession ($Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://PRDEXC01-VM/Powershell/ -Authentication Kerberos)

  Get-Content -Path $InputCSVPath |
  Get-MailBox | 
  % {
    Write-Host "Processing .... $($_.Name) ..." -ForegroundColor Green

    # Check if the file already exist or not
    if ( !(Test-Path -Path "$ServerBackupUNCPath\$($_.PrimarySmtpAddress).PST" -PathType Leaf) ) {
        #If there is no exported .PST file on the destination folder, then begin the export mailbox command and log if there any error to the AliasName.LOG file:
        New-MailboxExportRequest -Mailbox $_.EmailAddress -FilePath "$ServerBackupUNCPath\$($_.PrimarySmtpAddress).PST" -BadItemLimit 50 -AcceptLargeDataLoss -WhatIf
        # wait until error or processed:
        while ( ($req = Get-MailboxExportRequest $_.EmailAddress) | ? { $_.Status -match 'Queued|InProgress' } )
        { Start-Sleep 180 } 
        $req | Get-MailboxExportRequestStatistics -IncludeReport | Select-Expand Report | Out-File "C:\Logs\$($_.Alias).log"
    } else {
        Write-Host "The user $($_.Alias) with file $($_.PrimarySmtpAddress).PST is already existing" -f Orange
        "user $($_.Alias) with file $($_.PrimarySmtpAddress).PST" | Out-File -Append $ExportExistsCSVPath
        # This doesn't make sense, no stats available!
        # Get-MailboxExportRequestStatistics -IncludeReport | Select -Expand Report | Out-File "C:\Logs\$($_.Alias).log"
    }

    # I assume, whatever line I put here will be executed regardless of any of the condition above is met or not
    Remove-Mailbox -Identity $_.EmailAddress -Confirm $false -WhatIf
    Write-Host "Just for testing: Removing Mailbox $($_.PrimarySmtpAddress)" -ForegroundColor Red
  }

输入文件内容：

Helpdesk@domain1.com
Support@domain2.org

错误消息类似于 PowerShell 控制台中的以下行：

Processing .... Helpdesk ...

添加名为 EmailAddress 的标头，然后我收到此错误：

如何更正上述 PowerShell 代码？

Answer 1

请参阅下面的更改。 'EmailAddress' 与 AD 中的代理地址相同，可以列出其中的几个，每个邮箱只有一 (1) 个'PrimarySmtpAddress'。还在 New-MailboxExport 上添加了“-Name”字段，这将使您更容易找到 Mailbox Export。

This is listed on the 
  New-MailboxExportRequest -Mailbox $_.EmailAddress
  Get-MailboxExportRequest $_.EmailAddress
  Remove-Mailbox -Identity $_.EmailAddress

Should be
  New-MailboxExportRequest -Name $_.PrimarySmtpAddress -Mailbox $_.PrimarySmtpAddress
  Get-MailboxExportRequest $_.PrimarySmtpAddress
  Remove-Mailbox -Identity $_.PrimarySmtpAddress
