Using office.365/Exchange with EmClient calendar

I have an email account using office365 Exchanger server. All of my calendar events, contacts and email folders are created in eMclient. The contacts, inbox and all inbox subfolders are appearing and syncing fine with my Exchange server account on my iphone but I do not see my calendar. The strange thing is that the calendar event notifications pop on the iphone but there is no calendar folder I can see so I can’t create or edit any events.
