Send-MailMessage ：SMTP 服务器需要安全连接或客户端未通过身份验证。这

Question

第一次发布海报 - 我整个星期都在谷歌上搜索！我对 Powershell 还很陌生，我正在尝试使用 Send-MailMessage。目标是在计划任务上设置 Powershell 脚本以发送自动电子邮件。我知道将 Powershell 脚本设置为计划任务有它自己的细微差别，我已经研究过，我想我知道接下来该怎么做，但在我到达那一点之前，当我调用脚本：

Send-MailMessage : SMTP 服务器需要安全连接或客户端未通过身份验证。服务器 响应是：5.7.57 SMTP；在 MAIL FROM 期间，客户端未通过身份验证发送匿名邮件

$secpasswd = ConvertTo-SecureString “PASSWORD” -AsPlainText -Force

$mycreds = New-Object System.Management.Automation.PSCredential "user@domain.com", $secpasswd

Send-MailMessage -To "user@domain.com" -Subject "Subject" -SmtpServer "smtp.office365.com" -Credential $mycreds -UseSsl -Port "587" -From "user@domain.com"

我正在尝试使用 Office 365 发送邮件（您可以从 SMTP 服务器看到）。当我将其复制并直接粘贴到控制台时，这可以正常工作，但是当我尝试使用以下命令调用脚本时，它会显示上述错误。

Powershell.exe -File C:\my_path\Script.ps1

我有什么遗漏的吗？可能是调用对其进行身份验证的脚本的更好方法？

任何帮助将不胜感激，我已经盯着各种论坛帖子好几天了！ :)

请查看我的 Github Gist 以获取此 Click Here 或查看下面的示例。

我遇到了同样的问题，似乎这是一条通用错误消息，大多数时候我在输入错误密码时收到此消息，但我相信没有 SendAs 权限会给出相同的错误，端口、SMTPServer示例中的和 UseSSL 参数是为我刚刚测试过的 Office365 配置的，并且可以正常工作。

还请注意，我提供了安全字符串的示例，如果您想将密码安全地存储在脚本文件中，则应使用此示例。

### Script Global Settings
#Declare SMTP Connection Settings
$SMTPConnection = @{
    #Use Office365, Gmail, Other or OnPremise SMTP Relay FQDN
    SmtpServer = 'outlook.office365.com'

    #OnPrem SMTP Relay usually uses port 25 without SSL
    #Other Public SMTP Relays usually use SSL with a specific port such as 587 or 443
    Port = 587 
    UseSsl = $true    

    #Option A: Query for Credential at run time.
    Credential = Get-Credential -Message 'Enter SMTP Login' -UserName "emailaddress@domain.tld"

    <#
    #Option B: Hardcoded Credential based on a SecureString
    Credential = New-Object -TypeName "System.Management.Automation.PSCredential" -ArgumentList @( 

        #The SMTP User Emailaddress
        "emailaddress@domain.tld"

        #The Password as SecureString encoded by the user that wil run this script!
        #To create a SecureString Use the folowing Command: Read-Host "Enter Password" -AsSecureString | ConvertFrom-SecureString
        "Enter the SecureString here as a single line" | ConvertTo-SecureString
    ) 
    #> 
}

### Script Variables
#Declare Mailmessages.
$MailMessageA = @{
    From = "emailaddress@domain.tld"
    To = @(
        "emailaddress@domain.tld"
    )
    #Cc = @(
    #    "emailaddress@domain.tld"
    #)
    #Bcc = @(
    #    "emailaddress@domain.tld"
    #)

    Subject = 'Mailmessage from script'
    #Priority = 'Normal' #Normal by default, options: High, Low, Normal
    #Attachments = @(
        #'FilePath'    
    #)
    #InlineAttachments = @{
        #'CIDA'='FilePath'
    #} #For more information about inline attachments in mailmessages see: https://gallery.technet.microsoft.com/scriptcenter/Send-MailMessage-3a920a6d

    BodyAsHtml = $true    
    Body = "Something Unexpected Occured as no Content has been Provided for this Mail Message!" #Default Message
}

### Script Start

#Retrieve Powershell Version Information and store it as HTML with Special CSS Class
$PSVersionTable_HTLM = ($PSVersionTable.Values | ConvertTo-Html -Fragment) -replace '<table>', '<table class="table">'

#Retrieve CSS Stylesheet
$CSS = Invoke-WebRequest "https://raw.githubusercontent.com/advancedrei/BootstrapForEmail/master/Stylesheet/bootstrap-email.min.css" | Select-Object -ExpandProperty Content

#Build HTML Mail Message and Apply it to the MailMessage HashTable
$MailMessageA.Body = ConvertTo-Html -Title $MailMessageA.Subject -Head "<style>$($CSS)</style>" -Body "
    <p>
        Hello World,    
    </p>

    <p>
        If your recieved this message then this script works.</br>
        </br>
        <div class='alert alert-info' role='alert'>
            Powershell version
        </div>
        $($PSVersionTable_HTLM)

#Send MailMessage
#This example uses the HashTable's with a technique called Splatting to match/bind the Key's in the HashTable with the Parameters of the command.
#Use the @ Symbol instead of $ to invoke Splatting, Splatting improves readability and allows for better management and reuse of variables
Send-MailMessage @SMTPConnection @MailMessageA
