Upfront apologies if this has been brought up before. I've tried to search and have read what threads I did find but nothing really clarified it for me. I'm running a 2014 Macbook Ai 11" using Mavericks with latest patches, and iCloud enabled to sync items with the calendar option enabled. So onto my problem.... The organization I work for uses exchange, I have a windows laptop at work, a macbook air at home, and for now...an android phone. I'm trying to simplify my life and I only want 1 calendar...per device. So on my macbook I added my Gmail and exchange calendars. On the Air in ical when I make an event it shows up on the androids calendar. Likewise if I add something on the android it gets pushed to iCal. Awesome...success...sort of. When I added exchange to iCal, whatever items I had on my exchange calendar appeared in ical. However any new events I add to exchange do not appear in ical. Likewise events I create in ical don't appear in my exchange calendar. I'm assuming this will resolve itself once I switch to an iPhone however for now I'm stuck with the Android. I just want Google calendar, ical, and exchange to be friends and stay sync with any entry I add. Am I asking too much? I've tried to refresh ical, I have it set to 1 min updates but it doesn't seem to want to pull from exchange. Or push updates to exchange. And just to mention again I'm using windows 7 at work with Outlook 2010. I DO NOT use Outlook on my Macbook, or even mail for that matter. I'm only using ical, Google calendar on the android, and Outlook on windows. Thanks in advance for any replies.
