Description: Uses Win32::OLE to edit your Outlook mail from Vim (here, gvim). Not very sophisticated, but demonstrates the use of Win32::OLE to control the Outlook Object model.

To use:

  • Save the script as vmail.pl
  • Run pl2bat vmail.pl
  • Move vmail.bat into your PATH
  • When you have an Outlook message window open, do Start - Run - vmail
  • Make your changes, save and exit.
UPDATE: Modified so that if there is no active item, a new mail message will be created.
