This is something that I consistantly wonder about when I send an email that includes attachments.
Say I'm working on a Word document and I want to email it to some co-workers. I open up Outlook and click the Attach file button to attach my Word document to the email. However, before I click Send, I realize that I want to make a last-minute change to the document, so I quickly switch to Word and modify the document, and then click Save. Do I have to remove the attachment in the email and re-add it? Or will the newest version be sent?
Essentially, I'm asking if Outlook will cache a copy of the file to be sent with the email as you're composing it.
