Question

我已经构建了powershell脚本，并且我在CSV文件中输出了“随机”位。字符串是MailboxExport（和一个数字）。它看起来像（Get-MailboxExportRequest）.name将返回的值，但我无法看到我会在哪里拉这样的东西或它是如何插入的。我想我可能只是盯着它看太久了，我可能只需要一双新眼睛来发现我的错误。我会进入脚本试图做的事情，但我在脚本中放了很多笔记，可以很好地解释它。

##################################################  PST Extraction Script  ##################################################
# Completed October 2013 by Trey Nuckolls
#
# This script is meant to extract PST files from the Site 1 Exchange server at the Site2 site and deliver those PST
# files to a share on the Site2 network.  The script will change the input CSV file to keep track of which PSTfiles have been
# extracted and when that occoured.  The script will also set security on the PST file so only the user and IT administraion
# can access the PST file.
#
# To run this script, enter the username of the Site 1 domain account that you want to target for extraction of a PST file then
# Run the script.  Can be run from any machine on the network as long as it is run by someone with domain admin rights on the
# Site 2 network.  Powershell v2 or v3 is required to run the script.

Answer 1

问题确实很可能是由New-MailboxExportRequest引起的，正如您已经怀疑的那样。 cmdlet打印有关创建的对象的信息，该信息与您在循环中创建的其余输出集中在一起，然后分配给变量$Processed。

为避免这种情况，您可以像这样抑制cmdlet输出：

New-MailboxExportRequest -Mailbox ... | Out-Null

或者像这样：

New-MailboxExportRequest -Mailbox ... >$null

将输出分配给变量也应该有效：

$exportRequest = New-MailboxExportRequest -Mailbox ...

Answer 2

在Export-CSV上，尝试添加标志：“ - NoTypeInformation”

Answer 3

我认为这可能是自定义对象与另一个现有对象（可能是Exchange服务器上的mailboxexportrequest对象）之间的某种名称空间交叉问题。在搞乱了一段时间后，我能够以一种新的方式让它失败，其中生成的csv文件充满了来自邮箱导出的详细信息，并且它们是一个也列出了用户名的“名称”列。我将输入csv上的哈希值从'name更改为'username'，并且生成的MailboxExport条目已停止。现在有空白行，但我当然愿意忍受这种不完美，因为它不会破坏这个（短暂的）过程。

如果有人对根本原因有任何了解，我当然希望听到它是什么，但我想我已经找到了解决方案，我可以忍受。
