What does this Automator Workflow do?  Saves selected email messages as files

How do I make this Automator Action?  Follow these steps (See Figure 1):
Open the Automator application (Double-click Automator.app in the Applications folder)
When Automator opens, a dialog displays “Choose a template for your workflow” with “workflow” selected by default. “Workflow” is what we want, so all you have to do is click the Choose button.
In the list of Actions in the left column, in the Library category choose Mail.
Drag the action, “Get Selected Outlook Items” to the empty pane on the right. It might take a couple tries before this works. Drag slowly.
Also from the Mail actions in the left column, drag the action “Save Outlook Items as Files” to the pane on the right as shown here.
In the Save Outlook Items as Files action, you can choose:
Where: Click this pop-up to choose the default folder in which to save the messages when the action runs
Save: Choose whether to automatically use the message subect as the file name or be prompted to enter a file name.
Options
Show this action when the workflow runs (recommended)
Show only the selected items (try this both ways and see how you like it)
You can test this action right in the Automator application. Switch to Outlook, and select one or more (hold the command key down and click on subjects to select them, or you can even use Command-a to select them all). The switch back to Automator application and click the Run button. The workflow runs and saves each selected message as a file.

You can save This Automator workflow so you can open and edit it again in Automator:
In Automator, choose File > Save As.
In the Save As field, give the action a name, such as SaveOutlookMessagesAsFiles.workflow
Use the default file format, “workflow” and then click the Save button.
To save this Automator Action as an application that Microsoft Outlook can use:
In Automator, choose File > Save As.
Change the file format pop-up to Application
In the Save As field, give the action a name, such as SaveOutlookMessages.app
Navigate to Documents > Microsoft User Data > Outlook Script Menu Items folder, then click the Save button.
All done! You can quit Automator application now.

How do I use a workflow that was saved as application?
In Microsoft Outlook 2011:
In a mailbox, elect the messages you want to save as files
Hold the Command key down to select more than one message
Hold the Shift key down to select a range of messages
Press Command-a to select all messages
Click on the Script Menu button (it looks like a scroll and is immediately to the right of Help in the Outlook Menu bar), and then choose the workflow application you saved as an application as described earlier.
Choose the options you want in the dialog box
Click the Continue button.
The selected mail messages have been saved to the folder you chose.
