When using Send Email feature in virtualized Adobe Reader to send pdf attachment, the email will be sent only once, and all further emails will not appear in Outlook Sent or Outbox folders, and in general there will be no track of those emails anywhere.
When the first email is being sent, there is a hidden entry added for tmp outlook data file, looking like email@example.com
After that no further emails with pdf attachments will be sent out of the Adobe Reader GUI.
Add [LOCALAPPDATA]\Microsoft\Outlook and subfolders to Exclude entries on Adobe Reader layer.
