从代理地址 powershell 获取主 SMTP

Question

I am working on the script below, The posted script works; unfortunately I need to pull the address from proxyaddresses PrimarySMTP (pulling it from email field in script). I have tried this process like crazy and cant get it to pull and output the info. Hoping someone could point me in the right direction.

$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

    }

}

Obviously I cannot test this but there are a few things I noticed, so I cleaned it up a bit below:

1. EmailAddress is not an AD property you are looking for "mail"
2. mail sometimes differes from the primary SMTP address on the ProxyAddesses property. That property returns as a string array. To isolate the primary you need to look for the one starting with capitol "SMTP:". Below I used the string .StartsWith() method to isolate it. The method is case sensitive so it should work.

I also removed a lot of piping to Where-Object because you can use the -and operator.

If you have no reason to believe the mail property will stray from the primary address on the ProxyAddresses property just use it like:

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

Otherwise you can parse ProxyAddresses like:

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

Obviously this is very crude considering I'm not in your situation, but should give you enough to get through it. Let me know how it goes.
