IOS11.3 does not support exchange

Works for me on iOS 11.3.1 and has always worked since iOS 8.x(?) when I loaded whatever version of Outlook was valid 2 years ago. I have been using Exchange Mail and calendar consistently from our company server with zero issues. I suggest the problem may be either incorrect setup, or compatibility between Microsoft’s server and Microsoft’s Outlook client.

Undortunately you just just claim it is not supported and don’t explain what you see or why you think it does not work, so we can’t make any useful suggestions about setup to help you get it working.

IOS11.3 still (iPhone 7) does not support exchange neither for email nor for calendar. There is not sync and no update of data and entries. When will this be fixed?

Strange. I am using the built in Mail and Calendar apps for 2 Exchange accounts. Both work. So there is nothing for Apple to fix. There is probably something for you or your sysadmin to fix.

Plenty of people in my organization that use Exchange for calendars, contacts, email, etc. without any issues. Some are still on iOS 10 but most are on iOS 11. Items sync between the desktop and the iPhone and vice versa almost immediately.

Unfortunately there is no network administrator. Our company is directly settled on the microsoft server (Office 365).

Please contact the folks at Microsoft Office 365 support for assistance. They're the folks that are supporting your Office 365 server and your local client configuration settings.

I'm using it for calendar with no problems at all. I prefer to get my mail through the Outlook app to keep it separate from my personal mail.

I'd suggest you talk to your network administrator.

Then maybe talk to Microsoft. It sounds as if something is amiss in how you've got things configured.
