ol2ical is a simple program to parse an Outlook calendar e-mail message and insert the event in ical's ~/.calendar file. ical is a Unix calendar application.
Output is sent to stdout, so it is necessary to specify appending to a file, like so:
ol2ical -f $TMPFILE >> ~/.calendar
where $TMPFILE is a file containing one or more mail messages containing Outlook calendar events.
ol2ical will parse mmultiple message types from Outlook, including recurring events and notes.
There is a Perl script named outlook2ical.pl but I found it had trouble with time calculations, and also didn't seem to handle all of the events I was receiving in e-mail, so I went ahead and implemented something in C that does the job.
I use a simple shell script to filter all of my e-mail (into different mailboxes for mailing lists, trash spam, etc.). If you use ol2ical with procmail (or other dedicated mail filtering tool) let me know your results (good or bad).
