Thanks to Exchange Active Sync technology added since Microsoft Exchange server 2003, all synced devices can exchange data in a manner that prevents deleting, duplicating or corrupting data.

This one-way syncing means that your calendar events will not be updated on your PC if you change or modify something on your smartphone.

This may cause variety of problems, starting with missed meetings and ending with potential problems with your work.

Exchange server is what many business owners use to sync Outlook calendar and contacts with their smartphones.

Exchange server works like a connection point between your PC and smartphone.

It would be better if you could do it using an Android or Windows Phone device.

This test will definitely show whether it’s i OS or an Exchange problem.Another i OS 11 issue that has been making some noise recently is related to the new Control Centre that does apparently does not fully turn off Wi-Fi and Bluetooth when toggling the buttons.However, unlike the email issue, Apple says that this is not a bug and is intentional so that users can continue to connect their i Phone or i Pad for Air Drop, Air Play, Apple Pencil, Apple Watch, Hotspot, and Location Services in the background.If you’re having problems with Exchange calendar on your i Phone, the easiest way to pinpoint the problem is to connect your Exchange Server with another smartphone and attempt to sync the same data as you are trying to sync on i Phone.If the other smartphone works better, the problem is with your i Phone.Interestingly, the bug was first discovered by beta testers of i OS 11, and it looks like Apple was unable to fix it before releasing the final build.
