无法使用Send-Mailmessage在电子邮件中嵌入图像

Question

我是PowerShell的新手，在将图像嵌入自动电子邮件中时遇到问题。 我正在使用Technet的Robert Pearman脚本的修改版本。 电子邮件本身将发送给任何密码将在未来14天内到期的用户。

该脚本在AD中扫描帐户，检索所有详细信息，并向其发送个性化的电子邮件。

我将带有HTML的图像嵌入到电子邮件中时所读的一切都失败了。 它看起来很简单，但是当电子邮件到达时，电子邮件始终显示红色的X HTML占位符图像。

$smtpServer= "SMTP.company.biz" 
$expireindays = 14
$from = "Helpdesk <helpdesk@company.biz>"
$logging = "Disabled" # Set to Disabled to Disable Logging
$logFile = "<log file path>" # ie. c:\mylog.csv
$testing = "Enabled" # Set to Disabled to Email Users
$testRecipient = "admin@company.biz"
$date = Get-Date -format dd-MM-yyyy
#$images = @{image1='D:\Script_Folder\Overwatch_images\FFPasswordChange.jpg'}
$AttachmentPath = "D:\Script_Folder\Overwatch_Images\FFPasswordChange.jpg"
$Attachment = New-Object System.Net.Mail.Attachment($AttachmentPath)
$Attachment.ContentID = "image1"

# Check Logging Settings
if (($logging) -eq "Enabled")
{
# Test Log File Path
$logfilePath = (Test-Path $logFile)
if (($logFilePath) -ne "True")
{
    # Create CSV File and Headers
    New-Item $logfile -ItemType File
    Add-Content $logfile "Date,Name,EmailAddress,DaystoExpire,ExpiresOn"
}
} # End Logging Check

# Get Users From AD who are Enabled, Passwords Expire and are Not   Currently Expired
Import-Module ActiveDirectory
$users = get-aduser -filter {MemberOf -eq "Group1,OU=Groups,OU=Group   Companies,DC=Company,DC=Biz"} -searchbase "OU=Users,OU=Group Companies,DC=Company,DC=Biz"   -properties Name, PasswordNeverExpires, PasswordExpired, PasswordLastSet,   EmailAddress, samaccountname | where {$_.Enabled -eq "True"} | where {   $_.PasswordNeverExpires -eq $false } | where { $_.passwordexpired -eq $false   }
$DefaultmaxPasswordAge = (Get-  ADDefaultDomainPasswordPolicy).MaxPasswordAge


# Process Each User for Password Expiry
foreach ($user in $users)
{
$Name = $user.Name
$emailaddress = $user.emailaddress
$passwordSetDate = $user.PasswordLastSet
$samaccountname = $user.samaccountname
$PasswordPol = (Get-AduserResultantPasswordPolicy $user)
# Check for Fine Grained Password
if (($PasswordPol) -ne $null)
{
    $maxPasswordAge = ($PasswordPol).MaxPasswordAge
}
else
{
    # No FGP set to Domain Default
    $maxPasswordAge = $DefaultmaxPasswordAge
}


$expireson = $passwordsetdate + $maxPasswordAge
$today = (get-date)
$daystoexpire = (New-TimeSpan -Start $today -End $Expireson).Days

# Set Greeting based on Number of Days to Expiry.

# Check Number of Days to Expiry
$messageDays = $daystoexpire

if (($messageDays) -ge "1")
{
    $messageDays = "in " + "$daystoexpire" + " Tagen"
}
else
{
    $messageDays = "heute."
}

# Email Subject Set Here
$subject="Ihr eIPN Passwort endet $messageDays"


$body = "

# If Testing Is Enabled - Email Administrator

    $emailaddress = $testRecipient    
}# End No Valid Email

# Send Email Message

{
     # If Logging is Enabled Log Details
    if (($logging) -eq "Enabled")
    {
        Add-Content $logfile    "$date,$Name,$emailaddress,$daystoExpire,$expireson" 
    }

    # Set Parameters
    $params = @{
    #InlineAttachements = $Images
    #Attachments = 'D:\Script_Folder\Overwatch-  Images\FFPasswordChange.jpg'
    Body = $body
    BodyasHTML = $true
    Subject = $subject
    From = $from
    To = $emailaddress
    SMTPServer = $smtpServer
    }

    # Send Email Message
    Send-Mailmessage @params -Priority High

    # -smtpServer $smtpServer -from $from -to $emailaddress -subject   $subject -body $body -bodyasHTML -InlineAttachments $images -priority High  


} # End Send Message

} # End User Processing



# End

在代码中，我仍旧进行了一些较早的尝试。 我感觉自己走在正确的道路上，但从未正确执行。

如果有人能看到我出了问题的地方或向正确的方向指出，那将是万分感谢！

如果您具有PowerShell v4，则可以使用splatting和Send-MailMessage 。

$attachment = Get-Item C:\temp\WhiteLogo.png

$params = @{
    To = "address"
    From = "address"
    SMTPServer = "theIP"
    Subject = "Stuff"
    BodyAsHTML = $true
    Body = 'Testing Inline <br /><img src="{0}" />' -f ($attachment.Name)
    Attachments = $attachment.FullName
}

Send-MailMessage @params

在v4中引用内嵌图像的逻辑似乎已得到改进。
