Q: iOS 10 exchange calendar sync issue

iOS 10 has introduced a bug that causes a problem with Exchange calendar sync. I am using an iPhone 5S and an iPad Air, with iOS 10.0.2 on both. My employer provides a shared calendar using Office 365 Exchange. I use Outlook 2013 on a Windows 7 laptop. Ever since I upgraded my iPhone & iPad to iOS 10 I've encountered a problem with syncing my calendar. Specifically, when I delete a single instance of a recurring event from my iPhone or iPad, the change does not sync to the server and is not reflected on my other devices. There is no problem if I do the deletion from Outlook on my laptop. I use recurring all-day reminders as "to-do's" so not being able to delete them from the device is a problem for me.

 

Based on something I saw in another form I tried disabling the "Events Found in Apps" button in Settings on my iPhone and iPad, and then disabling and re-enabling the Exchange calendar sync. This didn't resolve the problem.

 

Is there a fix or a workaround for this issue? If not, does anyone know how I can report this to Apple on the off chance they might care enough to fix the problem?

iPhone 5s, iOS 10

    I am having the exact same issue. Items on my exchange calendar are disappearing on my iPhone which is a major issue since I use my phone as my main calendar reminder to be in the right place at the right time. It's a serious problem for me. I tried removing and adding the calendar back in, turning my phone off and on, nothing is working. Now I have even less appointments showing, it's like it deleted them all. I'm exceedingly frustrated.

    UPDATE: I may have jumped the gun by assuming this was a problem introduced in iOS 10. It may have been a problem before I upgraded my iPhone & iPad and I only just realized it because I was traveling recently and relying on my mobile devices to update my calendar.

     

    For me it's only the recurring appointments that are an issue: I can add, edit, and delete non-recurring appointments with no problem. When I try to delete just once instance of a recurring calendar entry, however, the entry isn't deleted on the server, and in Outlook the entry is changed to a "meeting invitation" and the "to" line is left blank.

     

    I create all-day, recurring reminders (weekly and monthly, with no end date) to prompt me about actions I need to take on specific days.

     

    The only workaround I have found is to download the Outlook iOS app and use that, as it syncs directly with Exchange rather than syncing through the native iOS calendar. But this is not an ideal solution as I have an app from my gym that allows me to automatically create calendar entries for classes I scheduled, but it requires that I use the native iOS calendar.
