Q: Exchange calendar not syncing after iOS 9 update

I am using google Apps for business (no two steps authentication) and Exchange calendar stops syncing after iOS 9 update (now running on iOS 9.0.1) . It is happening both on iPad and iPhone and started after the update.

I have already tried resetting both devices (and set up as new device without restoring from iCloud backups), it works for a few hours and then it stops again. The temporary solutions of either disabling the calendar sync and re-enable it or deleting the Exchange account and setting it up again, works for only a few hours.

Does anyone else experiencing the same problem?

iPhone 6, iOS 9.0.1

    I have the same issue but we are using Exchange 2013. When using the OWA app or webmail the calendar is empty on  iphones since the iOS9 update. Mail and calendars are fine. I've tried re-setting it up and the calendar remains empty. I've confirmed it is still working on devices that did not run the update.

    I have the same problem with my iPhone 6. In settings > mail,contacts,calendars, locate your Exchange account. 

    Once in the Exchange, toggle the switch for calendar only to off.  Reboot the phone.  Once I did this, the calendar repopulated and is working to accept entries in both directions (phone to google and google to phone). 

    CAUTION:  Any entries you made in your iPhone since the upgrade, that did not transfer to gmail, will be wiped out.

    It only works for some short period of time. After a few times syncing, it stops... at least in my case.

    Now it seems I get more stable sync on the iPhone compared to iPad (which took less than 30 minutes to stop syncing).

    Hi Troy1954

     

    did you manage the find a fix for this?  I am seeing the same issue and have temporarily swapped the clients to the outlook app.

     

    I am a couple of CU's behind on exchange and was thinking this might help.

     

    thanks

    Russ

    I might have found the solution (still testing but seems to be working for now).

    Turn off the "Events Found in Mail" feature added in iOS 9 (Settings->Mail, Contacts,Calendars-> scroll all the way down to Calendar section and turn off Events Found in Mail).

    Then turn off the calendar sync in Exchange and turn it back on.

    I was having the same problem and tried your solution.  So far....seems to be working.  I think you nailed it!

    Nope after several hours it stopped again.  Turning calendar off and on seems to give you a slight reprieve but then it comes back.

     

    Seeing it on IOS 9, 9.01 and 9.1 beta 2 on a variety of iphones hitting activesync with Google Apps. 

     

    Best way to recreate is to create a calendar item on your gmail calendar and it should almost immediately appear on your iphone calendar.  But once affected it will not.  If you use the Google Calendar app it does immediately appear.

    I'm experiencing this on a wide variety of devices. We're using AirWatch to manage over 600 iOS Devices in the field, Google Apps to handle the Cal.

    Here is what I tried so far tried, So don't waste your time trying these:

    -turn Calendar Sync OFF / On

    -updating to 9.0.1

    -updating to 9.0.2

    -complete wipe and restore (iCloud)

    -complete wipe and restore (iTunes)

    -tested on the native Google Calendar App (Faster, but same results over a few hours)


    Its clear that this is related to ActiveSync. I read that one of the features of iOS 9 in the Enterprise was "Improved calendar reliability for customers using Microsoft Exchange ActiveSync v16"

    Could that be a lead on something to look into? I'm not an expert in Exchange but maybe someone could please provide some insights?

    So if this is Active Sync related, who do we look to for a fix? Microsoft, Apple, or Google?

    According to this it's Apple.
