This thread is only concerned with operations on iPhone and iPad. I have no issues working with PC's.
We are using Exchange 2013, on premises Server. My company has a shared calendar for different sales reps to schedule items with.
I cannot SHARED CALENDARS on any IOS Device, whether I use Outlook Web Access in browser from Safari or Chrome, or the OWA App for Iphone/Ipad, or the Outlook App. The native Exchange Access on the iphones/ipads does not have a way(that I know of) to access shared Calendars. We are on Exchange Server 2013 Service Pack 1 (SP1 aka CU4) 15.0.847.32 , some research suggests that I need to update the Exchange server to the latest service release CU12. During initial testing it did work ok My Iphone, but it is running IOS 8.3. I am thinking this is related to something with IOS 9, as others have mentioned on Apple Forums (with no solution given). So should I update the Exchange server to the latest CU12 to see if that fixes the issue? Has anyone dealt with this issue before?
