从 Proxyaddresses powershell 获取主 SMTP

Question

我正在编写下面的脚本，发布的脚本有效；不幸的是，我需要从proxyaddresses PrimarySMTP 中提取地址（从脚本中的电子邮件字段中提取地址）。我已经疯狂地尝试了这个过程，但无法让它提取和输出信息。希望有人能指出我正确的方向。

$CountA = 1

$CountB = 0

 

Function PasswordExpiration

{

        While ($CountB -ne 5)

    {

        $CountA = $CountA + 1

        $CountB = $CountB + 1

        $FinalPath = "c:\support\PasswordExpiration\PasswordExpiration"+$CountB+"Days.csv"

        $FilterEndDate = (Get-Date).AddDays($CountA).Date

        $FilterStartDate = (Get-Date).AddDays($CountB).Date

        Get-ADUser -Filter * -Properties "DisplayName", "msDS-UserPasswordExpiryTimeComputed" , 
        EmailAddress, DisplayName, PasswordNeverExpires | 
        where EmailAddress -ne $null |
        where { $_.passwordNeverExpires -eq $false } | 
        where {$_.enabled -eq $true}|

            Select-Object -Property "Displayname", GivenName , EmailAddress,@{Name="Expiration Date";Expression={[datetime]::FromFileTime($_."msDS-UserPasswordExpiryTimeComputed")}}, PasswordNeverExpires, enabled |

            Where-Object { $_.'Expiration Date' -lt $FilterEndDate} |

            Where-Object { $_.'Expiration Date' -gt $FilterStartDate} |

            Export-Csv -Path $FinalPath -Encoding ascii -NoTypeInformation

    }

}

显然我无法对此进行测试，但我注意到了一些事情，所以我在下面清理了一下：

1. EmailAddress 不是您要查找“邮件”的 AD 属性
2. 邮件有时与 ProxyAddesses 属性上的主 SMTP 地址不同。该属性作为字符串数组返回。要隔离主节点，您需要查找以首字母“SMTP：”开头的主节点。下面我使用了字符串.StartsWith() 方法来隔离它。该方法区分大小写，因此应该可以使用。

我还删除了很多到 Where-Object 的管道，因为您可以使用 -and 运算符。

如果您没有理由相信邮件属性会偏离 ProxyAddresses 属性上的主地址，请像这样使用它：

Function PasswordExpiration
{
    $ExpirationDate = @{Name = "Expiration Date"; Expression = { [DateTime]::FromFileTime( $_."msDS-UserPasswordExpiryTimeComputed" ) } }
    While ($CountB -ne 5)
    {
        $CountA = $CountA + 1
        $CountB = $CountB + 1

        $FinalPath  = "c:\support\PasswordExpiration\PasswordExpiration"+$CountB+"Days.csv"
        $Properties = "DisplayName", "msDS-UserPasswordExpiryTimeComputed", "mail","ProxyAddresses", "PasswordNeverExpires"
        
        $FilterEndDate   = (Get-Date).AddDays($CountA).Date
        $FilterStartDate = (Get-Date).AddDays($CountB).Date

        Get-ADUser -Filter * -Properties $Properties | 
        Where-Object{$_.mail -and !$_.passwordNeverExpires -and $_.enabled } |
        Select-Object -Property Displayname, GivenName, mail, $ExpirationDate, PasswordNeverExpires, Enabled | 
        Where-Object { $_.'Expiration Date' -lt $FilterEndDate -and $_.'Expiration Date' -gt $FilterStartDate } | 
        Export-Csv -Path $FinalPath -Encoding ascii -NoTypeInformation 
    }
} # End Function PasswordExpiration

否则你可以像这样解析ProxyAddresses：

Function PasswordExpiration
{
    While ($CountB -ne 5)
    {    
        $CountA = $CountA + 1
        $CountB = $CountB + 1

        $FinalPath  = "c:\support\PasswordExpiration\PasswordExpiration"+$CountB+"Days.csv"
        $Properties = "DisplayName", "msDS-UserPasswordExpiryTimeComputed", "mail", "ProxyAddresses", "PasswordNeverExpires"

        #Calculated Property Expressions:
        $EmailAddress   = @{Name = "EmailAddress"; Expression = { ( ( $_.ProxyAddresses.Where( { $_.StartsWith( 'SMTP:' ) } ) ) -replace 'SMTP:' )  } }
        $ExpirationDate = @{Name = "Expiration Date"; Expression = { [DateTime]::FromFileTime( $_."msDS-UserPasswordExpiryTimeComputed" ) } }
                
        $FilterEndDate   = (Get-Date).AddDays($CountA).Date
        $FilterStartDate = (Get-Date).AddDays($CountB).Date

        Get-ADUser -Filter * -Properties $Properties | 
        Where-Object{$_.mail -and !$_.passwordNeverExpires -and $_.enabled } |
        Select-Object Displayname, GivenName, $EmailAddress, $ExpirationDate, PasswordNeverExpires, Enabled  |
        Where-Object { $_.'Expiration Date' -lt $FilterEndDate -and $_.'Expiration Date' -gt $FilterStartDate } |
        Export-Csv -Path $FinalPath -Encoding ascii -NoTypeInformation
    }
} # End Function PasswordExpiration

考虑到我不在你的情况下，显然这是非常粗略的，但应该给你足够的时间来度过它。
