PowerShell Outlook Scripting

This small PowerShell example opens my Outlook and searches for a inbox folder called „Planungen“.
It’s going through all mail and processes them if they have special keywords in them like Planung and KAR. If there are keywords like NB or Nachberechnung it’s not processed. Then it saves the attachment to a temporary Directory and uses pscp to copy it over to a linux machine. It uses my Windows kerberos key to authenticate via GSSAPI so I don’t need a RSA Key or password. It’s executed each day as a scheduled job. Neat, isn’t it?


$pscp_path="C:\Users\someuser\Downloads\pscp.exe"
$linux_path="somehost.de:/tmp"
$linux_user="someuser"
$filepath = "C:\temp\"
$date = get-date -format d
$time = get-date -format h-mm
$log = "C:\Temp\Logs\parameterpflege_" + $date + "_" + $time + ".log"

$olFolderInbox = 6 
$outlook = new-object -com outlook.application; 
$ns = $outlook.GetNameSpace("MAPI");
$inbox = $ns.GetDefaultFolder($olFolderInbox)
$planungsordner=$inbox.Folders | where-object { $_.name -eq "Planungen" }
$messages = $planungsordner.items 

foreach($message in $messages){
  If ($message.subject -match ".*Planung.*" -And $message.subject -match ".*KAR.*" -And $message.UnRead -eq "$true" -And (!($message.subject -match ".*NB.*" -Or $message.subject -match ".*Nachberechnung.*"))) {
    Start-Transcript -Force -Path $log
    $subject=$message.subject
    write-host "bearbeite Mail ""$subject"""
    # save attachment
    $message.attachments|foreach {
      $attachmentname = $_.filename
      If ($attachmentname.Contains("doc")) {
        Write-Host "save $attachmentname to $filepath"
        $_.saveasfile((Join-Path $filepath $attachmentname)) 
      } 
    }
    # mark as read so it's not gonna processed again
    $message.UnRead = $false
    $docfile = "$filepath" + $attachmentname
    Write-Host "kopiere $docfile nach $linux_user@$linux_path"
    &$pscp_path $docfile $linux_user@$linux_path
    Stop-Transcript
  }
}

convert Powerpoint to JPG or PNG or whatever

I had to find an easy solution for my colleaugue to convert Powerpoint files to e.g. JPGs.
They have a big screen where they want to do slideshows and the people do Powerpoint files for easy changes.
Instead of doing all manually with save as and such it should be an automatic conversion.

Here is the batch convertPowerpoint2JPG.bat I came up with:

@echo off
SET imagemagickpath=%~dp0
set filepath=%~dp1
set extension=%~x1
set filename=%~n1
echo convert Powerpoint to PDF
if exist "%filepath%%filename%.pdf" del "%filepath%%filename%.pdf"
CSCRIPT "%imagemagickpath%ppt2pdf.vbs" "%filepath%%filename%%extension%" "%filepath%%filename%.pdf"
if not exist "%filepath%%filename%" mkdir "%filepath%%filename%"
echo convert PDF to JPGs
"%imagemagickpath%convert.exe" -monitor -quality 100 -unsharp 0x1 -density 400 "%filepath%%filename%.pdf" -resize 60%% "%filepath%%filename%\%filename%.jpg"
exit /b

It uses a vbs Skript to invoke Powerpoint for pdf saving and then converts the PDF with ImageMagick (actually the embedded portable GhostScript) to JPG.

The code for ppt2pdf.vbs is:

Option Explicit

Sub WriteLine ( strLine )
    WScript.Stdout.WriteLine strLine

Sorry, I forgot the source. If you know it, let me know.

I used a portable version of ImageMagick and a portable version of GhostScript. You have to integrate GhostScript into ImageMagick in the file delegates.xml. Place GhostScript in ImageMagick folder and replace all appearances of gswin32c.exe with Ghostscript\bin\gswin32c.exe (if that is the path of your portable GhostScript).

Now just drag a ppt(x) file onto convertPowerpoint2JPG.bat and it creates a folder in the same directory where your ppt(x) resides and puts numbered JPGs in that folder.

You can download my example for trying it out yourself (Windows x64 version).
