iOS8 and Exchange Calendar

Since the iOS8 update, I have had the following issue:

I use Exchange for my calendar at work. When I override a single occurrance of a reoccurring meeting (via outlook on my PC), my phone changes back to the Original time, not accepting the change, then syncs with Outlook and essentially moves my meeting back to original time. My participants have the correct, updated meeting and I do not. How do I fix?
