Lost multiple calendars on ical/outlook client after itunes upgrade to 10.6 40
I have been sybcing my calendars between ical, outlook for mac, gmail, and others for over a year. I lost all calendar items that were not on my mac as of two days ago. The only update I can think of is an update to iTunes 10.6 40.
How do I recover?
Mac Pro, Mac OS X (10.6.8)
