# A demo plugin for Microsoft Outlook (NOT Outlook Express)
#
# This addin simply adds a new button to the main Outlook toolbar,
# and displays a message box when clicked.  Thus, it demonstrates
# how to plug in to Outlook itself, and hook outlook events.
#
# Additionally, each time a new message arrives in the Inbox, a message
# is printed with the subject of the message.
#
# To register the addin, simply execute:
#   outlookAddin.py
# This will install the COM server, and write the necessary
# AddIn key to Outlook
#
# To unregister completely:
#   outlookAddin.py --unregister
#
# To debug, execute:
#   outlookAddin.py --debug
#
# Then open Pythonwin, and select "Tools->Trace Collector Debugging Tool"
# Restart Outlook, and you should see some output generated.
#
# NOTE: If the AddIn fails with an error, Outlook will re-register
# the addin to not automatically load next time Outlook starts.  To
# correct this, simply re-register the addin (see above)
