Had a msg on my phone earlier to apply an update and went through with it. Since then, my corporate / exchange calendar is gone from the phone. If I go into the calendar settings to see what calendars are in sync I see the corporate calendar as an option that is checked. I can check/uncheck that all day and my calendar at work is never visible on the phone. Help!!! OK... just tested something. If I go into my calendar at work and modify any calendar entry (add a . at the very beginning of the msg) it will show up on my phone. So what I can gather I have to modify every calendar entry that is existing in order for it to display. I just tested adding a new meeting and that showed up. Ugh... this will be a pain.
