I'm having dinner with a work friend. We set up a meeting on our Outlook calendars and I forwarded the meeting to my iCould email. I accepted the invite on there and everything was OK. We had to reschedule and my buddy sent me the new invite. When it didn't change on my phone, I decided to try declining the event and resending it to me with the new time. However, now it wont let me add the event to my Calendar because it has me down as declining it and I dont' know how to change it. What can I do (short of just making my own Calendar event)?
