Why doesn't my calendar on iPhone 6 (iOS8) sync with Exchange?

I have an iPhone 6 running iOS8 and I'm having trouble with my calendar syncing with MS Exchange. I don't have trouble with normal calendar entries; it's only with recurring meetings. If the day/time is changed for the recurring meetings, my calendar in Outlook on my PC updates but the calendar on my iPhone does not causing me to miss meetings.

I've restarted the phone. I've turned the cellular data off/on. I'm not connected to any wireless networks.

Is anyone else having this problem?

I've finally solved the problem!! 😀

If I login to the exchange account's email there a bounch of email to the telling me that it has reach the maximum numbers of users on the exchange server..

The maximum phone users are set to 10..

So if you go to settings>phones>mobilephones and delete "old" phones.. There will be 10 spots open again.

So it's not and iphone IOS problem, but an exchange server problem... 🙂🙂🙂🙂

I found my disconnect:

Went into Mail, Contacts, Calendars>Default Calendar and changed default from iCloud Calendar to ACTIVESYNCE Calendar

Then went into the Calendar App >Calendars (middle bottom) and ensure ACTIVESYNC was checked.

The event that I had entered on my phone still hadn't synced. Found that it was also synced to iCloud. When I changed to ACTIVESYNC> Calendar it immediately showed up on my Outlook Calendar.
