iPhone Calendar Events not Syncing with Office 365

I am using email, calendar and contacts on Office 365 synced across aa laptop, desktop, iPhone and iPad.


All work perfectly except for one use case.


If I accept an event invitation on my iPhone it does not get synced to Office 365 or any other device. Looking at the event on my iPhone it shows as a different colour to other events. On the event I see a Calendar option which has Home, Work and two marked Untitled.


If I create an event on my iPhone it is always synced to all my other devices. Events created on other devices always get synced to my iPhone.


What do I need to do to resolve this?


Many thanks...Peter
