Fixing Autofiling Script for Outlook

So somewhere along the way, my auto-filing script for outlook began failing. When selecting a single message and executing the script in outlook, it failed. So I fixed the error and cleaned up the script a bit.

The issue was that when I was selecting only one item, it didn't understand the message "count" so it crashed. So after about 30 minutes of trying stuff, I decided to cast as a list. It's now working for me.

-- Changed script to parse out the first part of the email address as the folder name, eliminated time stamp folder
-- Changed to run as triggered script vs email rule
-- explanation of what and why at scrubbs.me

-- set up the attachment folder path
tell application "Finder"
    set folderName to "Attachments"
    set homePath to (path to home folder as text) as text
    set attachmentsFolder to (homePath & folderName) as text
      -- display dialog attachmentsFolder
end tell

tell application "Microsoft Outlook"
    set theMessages to selection as list

    repeat with eachMessage in theMessages
            -- set the sub folder for the attachments to the first part of senders email before a period
        -- All future attachments from this sender will the be put here.

        set theSender to sender of eachMessage
        set theAddress to address of theSender

        -- display dialog theAddress
       set AppleScript's text item delimiters to "."
       set senderName to text item 1 in theAddress
       set subFolder to senderName

        -- display dialog senderName

        -- use the unix /bin/test command to test if the folder exists. if not then create it and any intermediate directories as required
        if (do shell script "/bin/test -e " & quoted form of ((POSIX path of attachmentsFolder) & "/" & subFolder) & " ; echo $?") is "1" then
            -- 1 is false
            do shell script "/bin/mkdir -p " & quoted form of ((POSIX path of attachmentsFolder) & "/" & subFolder)
        end if

        try
            -- Save the attachment
            -- repeat with theAttachment in eachMessage's attachment
            set theAttachment to every attachment of eachMessage
            repeat with theFile in theAttachment
                set originalName to name of theFile
                set savePath to attachmentsFolder & ":" & subFolder & ":" & originalName
                try
                    save the theFile in file (savePath)
                end try
            end repeat
        end try
    end repeat
end tell
