利用powershell指令發email，一次發送多筆email及多個附加檔(attach files)

如果我們使用exchange server，可以利用指令的方式發送email。

可以利用exchange server的ps指令，Send-MailMessage or powershell配合 .net的一些方式來做。

利用指令還有一個好處就是可以定時發送。

我的需求是希望已類似合併列印的方式來發email，做一個csv檔，將每一筆要合併的資料放入，例如email address、人名、電話、要附加的檔案名稱、郵件內容....等，利用powershell執行一程式直接合併後email給收件人。

國外有很多的例子可以參考，如要引用的話要針對自己的環境修改哦，整理了我有使用的如下，(我依我的環境更改後，它是work的)

參考Chris's Blog如下：
做一個類似下圖的csv檔

script如下： 一定要依自己的環境更改以下的變數。

# Function to create report email

function SendNotification{

 $Msg = New-Object Net.Mail.MailMessage

 $Smtp = New-Object Net.Mail.SmtpClient($ExchangeServer)

 $Msg.From = $FromAddress

 $Msg.To.Add($ToAddress)

 $Msg.Subject = "Announcement: Important information about your office relocation."

 $Msg.Body = $EmailBody

 $Msg.IsBodyHTML = $true

 $Smtp.Send($Msg)

}

 

# Define local Exchange server info for message relay. Ensure that any servers running this script have permission to relay.

$ExchangeServer = "yourexchange.domain.com"

$FromAddress = "Office Relocation Team "

 

# Import user list and information from .CSV file

$Users = Import-Csv UserList.csv

 

# Send notification to each user in the list

Foreach ($User in $Users) {

 $ToAddress = $User.Email

 $Name = $User.FirstName

 $Level = $User.Level

 $DeskNum = $User.DeskNumber

 $PhoneNum = $User.PhoneNumber

 $EmailBody = @"

 

 

 

 

 Dear $Name,

 

 As you know we will be relocating to our new offices at 742 Evergreen Terrace, Springfield on July 1, 2015. This email contains important information to help you get settled as quickly as possible.

 

 Your existing access card will grant you access to the new building and your desk location is as follows:

 

 Level: $Level

 Desk Number: $DeskNum

 Phone Number: $PhoneNum

 

 Your new phone will be connected and ready for use when you arrive.

 

 If you require any assistance during the move please contact the relocation helpdesk at relocation@gooselabs.net or by calling 555-555-1234

 

 Regards,

 

 Office Relocation Team
