是否可以仅从公用文件夹中提取 SMTP 地址

Question

我正在尝试使用 get-mailpublicfolder 命令提取与我们的某些 Exchange 2010 公用文件夹关联的 SMTP 地址列表

虽然我可以提取 WindowsEmailAddress 和 EmailAddresses 值，但后者包含我想排除的 X400 地址。

我能找到的与此相关的最接近的是以下链接中列出的代码

https://unlockpowershell.wordpress.com/2010/01/27/powershell-get-mailbox-display-smtp-addresses/

但这似乎只适用于 Get-Mailbox，因为以下代码返回以下错误

$data=Get-MailPublicFolder -Identity $id |select-object WindowsEmailAddress,@{Name="EmailAddresses";Expression={$_.EmailAddresses}|Where-Object {$_.PrefixString -ceq "smtp:"}}| ForEach-Object {$_.SmtpAddress}

 

Select-Object : Key "Expression" has illegal type System.Management.Automation.PSObject; expected types are {System.Str

ing, System.Management.Automation.ScriptBlock}.

At C:\Temp\FindAllEmailAdresses_v1.ps1:33 char:56

+ $data=Get-MailPublicFolder -Identity $id |select-object <<<<  WindowsEmailAddress,@{Name="EmailAddresses";Expression=

{$_.EmailAddresses}|Where-Object {$_.PrefixString -ceq "smtp:"}}| ForEach-Object {$_.SmtpAddress}

    + CategoryInfo          : InvalidArgument: (:) [Select-Object], NotSupportedException

    + FullyQualifiedErrorId : DictionaryKeyIllegalValue1,Microsoft.PowerShell.Commands.SelectObjectCommand

Select-Object : Key "Expression" has illegal type System.Management.Automation.PSObject; expected types are {System.Str

ing, System.Management.Automation.ScriptBlock}.

或

$data=Get-MailPublicFolder -Identity $id |select WindowsEmailAddress,@{Name="EmailAddresses";Expression={$_.EmailAddresses}|Where-Object {$_.PrefixString -ceq "smtp:"}}

 

+ $data=Get-MailPublicFolder -Identity $id |select <<<<  WindowsEmailAddress,@{Name="EmailAddresses";Expression={$_.

ilAddresses}|Where-Object {$_.PrefixString -eq "smtp:"}}

    + CategoryInfo          : InvalidArgument: (:) [Select-Object], NotSupportedException

    + FullyQualifiedErrorId : DictionaryKeyIllegalValue1,Microsoft.PowerShell.Commands.SelectObjectCommand

Select-Object : Key "Expression" has illegal type System.Management.Automation.PSObject; expected types are {System.

ing, System.Management.Automation.ScriptBlock}.

是否可以只提取 SMTP 地址，还是我也坚持提取 x400 地址？ 提前致谢

编辑

根据答案，我已将代码更改为以下内容，并且可以进行一项更改，即从 -ceq "smtp:" 部分中删除冒号，因为将其保留在适当的位置会导致电子邮件地址没有被退回。请注意，这是我的错误，而不是 Dougs，因为他们只是基于我之前提供的代码。

$expression = {$_.EmailAddresses | Where-Object {$_.PrefixString -ceq "smtp"} | ForEach-Object {$_.SmtpAddress}}

$selectprops = 'WindowsEmailAddress',
               @{Name="EmailAddresses"; Expression=$expression}

$data = Get-MailPublicFolder -Identity $id | Select-Object $selectprops

Answer 1

这是格式化/缩进可以为您节省大量时间和挫败感的地方。您得到的错误是您的表达式（e={} 计算属性的一部分）只能是字符串或脚本块。简而言之，两个命令在错误的位置都有一个花括号。避免这种情况的一种真正简单的方法是将代码块存储在变量中。

这是移动了大括号的原始行。

$data = Get-MailPublicFolder -Identity $id |select-object WindowsEmailAddress,@{Name="EmailAddresses"; Expression={$_.EmailAddresses | Where-Object {$_.PrefixString -ceq "smtp:"}| ForEach-Object {$_.SmtpAddress}}}

和

$data = Get-MailPublicFolder -Identity $id |select WindowsEmailAddress,@{Name="EmailAddresses";Expression={$_.EmailAddresses|Where-Object {$_.PrefixString -ceq "smtp:"}}}

这是我真正推荐的

$expression = {$_.EmailAddresses | Where-Object {$_.PrefixString -ceq "smtp:"} | ForEach-Object {$_.SmtpAddress}}

$selectprops = 'WindowsEmailAddress',
               @{Name="EmailAddresses"; Expression=$expression}

$data = Get-MailPublicFolder -Identity $id | Select-Object $selectprops

或

$expression = {$_.EmailAddresses | Where-Object {$_.PrefixString -ceq "smtp:"}}

$selectprops = 'WindowsEmailAddress',
               @{Name="EmailAddresses";Expression=$expression}

$data = Get-MailPublicFolder -Identity $id | Select-Object $selectprops

注意

我保留了 powershell 2.0 代码格式，以防您卡在旧版本中。如果它是 5.1，那么这可能会被整理得更多。

$expression = {$_.EmailAddresses | Where-Object PrefixString -ceq "smtp:" | ForEach-Object SmtpAddress}

$selectprops = 'WindowsEmailAddress',
               @{Name="EmailAddresses"; Expression=$expression}

$data = Get-MailPublicFolder -Identity $id | Select-Object $selectprops

或

$expression = {$_.EmailAddresses | Where-Object PrefixString -ceq "smtp:"}

$selectprops = 'WindowsEmailAddress',
               @{Name="EmailAddresses";Expression=$expression}

$data = Get-MailPublicFolder -Identity $id | Select-Object $selectprops
