However, sometimes, due to misconfiguration, i Phone can connect to Exchange and pull data but fails to push any changes back to Outlook.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.If have a great deal of data or media on your i Phone, and factory reset is not an option, then downgrading to the previous i OS version might be your best option.Another way to identify the problem is setting up another Exchange account on your i Phone and testing how it works with calendar.With this software you can have your own Exchange server for syncing notes (as well as calendars, contacts and tasks) between your i Phone and Outlook.
Exchange server is what many business owners use to sync Outlook calendar and contacts with their smartphones.
If this hasn’t helped you, try to connect another i Phone to this Exchange server using the same credentials.
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.
If the second smartphone transfers data two-way without any problems, the problem is in your smartphone and Apple will definitely release an update in the near feature to fix the issue.
