iOS 7 calendar is not syncing with Exchange

I've done that too, and it didn't work.

I am having the same problem: After upgrading to a new iPhone 5s my Google calendar no longer syncs with the calendar on the phone. Google sync settings show that syncing is occuring, but new events were not showing up. So I deleted the account (which was an exchange account) and re-added it. It verified okay, but now there is nothing at all from my Google calendar on my phone. It still shows that syncing is happening to my iphone, but there are zero events on my phone now.

The instructions on Google's website say to just use the GMAIL account type, rather than Exchange, but this didn't work because my Google account is NOT xxx@gmail.com. I get a failure on the verification step. There's no instructions on the Google website on what to do in this situation, but I'm guessing that I'll have to change my account somehow to switch from my other email address as account name to something like xxx@gmail.com and then hope my existing calendar doesn't get deleted. Is there anyone else who is NOT using xxxx@gmail.com as their Google account name and has been able to sync calendars post-ios7 upgrade?

My issue is not my calendar or email, they are syncing fine. My issue is with my tasks (reminders). They will no longer sync after updating my iPhone 4S to IOS 7.0.2. Driving me CRAZY! Any help? My IT guys have no idea what to do.

fwiw -- I used these instructions and it worked perfectly:

1. sign onto Google Calendar

2. go to settings (where the little gear thing is on the upper right of screen)

3. Mobile Setup (follow setup steps on that page; verification code, etc.)

4. Reboot iOS device, open up cal, and watch it sync.

Good luck!

Same here. The google calendar does load but every time I added a calendar appointment or moved it (after upgrading to iOS 7), after a few seconds it disappeared or moved back. I tired every recommendation I could find on every forum. I tried every other thing I could possibly think of. Nothing worked. Not exchange account, not gmail account, not CALDAV.

Finally this is what I did to resolve the problem:

- when I set up the gmail account (for calendar as well as email on ipad) I use my @googlemail.com login name instead of the @gmail.com. (I have not technically switched to @gmail, even though @gmail works otherwise perfectly fine as login or email address ).

- the problem has gone and calendar appointments stay, both new and moved ones. After weeks of not being able to use the new ios 7 calendar I now can.

It sounds ridiculous that such a small thing should create such a headache to people for something as fundamental as a calendar.

I'm getting frustrated. The methods mentioned here are all hit and miss.

I have a 5s, 5 and 4s and all of them are giving me ****.

For the 5s, I finally got it and re-sync after I switch from exchange to google. And after I reset all settings.

But when I try to do the same for my 4s, it can't work. So I tried ALL the methods mentioned here and still does not work as of yesterday. This morning I check still no calendar showing up and did a reboot. Couple of hours later it mysteriously appear.

As for my 5, am still stuck with no calendar. Reset, reboot, delete, turn off, mobile verification, etc...I have tried it all.

I think this is a MAJOR bug.

Strangely on my iPad 3 and iPad mini the exchange sync still work well.

Shortly after I post this the calendar appears on my iPhone 5! Haha...so my suggestion is after doing the steps and rebooting the phone, give it time to appear 🙂

I removed my Google account which I use for syncing calender.

Then, added same account again - and all problems sorted!

Hope this helps.

Best wishes,

I'm using Outlook for Mac 2011 and iOS7.0.2 on my iPhone5 and found a somewhat easy/somewhat awkward solution for the calendar sync issue. It also sort of explains the overarching problem that seems to be happening.

First a little background, while on iOS6, I was unable to sync my Outlook for Mac calendar to my iPhone via iCloud. It would only work with a manual sync via iTunes. After upgrading to iOS7 (and then 7.0.2, the next week), I'd get a calendar sync issue when plugging in my phone.

I went to the Apple Store, and they had me switch from manual sync to iCloud sync, which initially seemed to work. Everything on my Outlook for Mac calendar appeared on my iPhone. I quickly realized, however, that while all previously created events had transfered over, new events were not appearing.

For those of you that use Outlook for Mac, you probably already know that in order to have your events appear on your calendar, you need to turn on "sync services" in Outlook, which then syncs your Outlook with iCal, then your iCal is what ultimately ends up syncing with your calendar on your iOS devices. After upgrading to iOS7 and then swithcing to an iCloud sync vs an iTunes sync (which stopped working with iOS7), my events on my Outlook were properly appearing in my iCal, but they were no longer transfering to my iOS devices.

I tried manually creating a test event in my iCal and immediately noticed the issue. When you create an event directly in iCal after turning on iCloud, you're given two options for saving the event; one to save the event locally on your Mac, the other to save it in iCloud. Choosing to save the event locally on my Mac will cause it not to appear on my iOS devices, but selecting iCloud, does cause it to properly appear on my iPhone/iPad.

As you can probably guess by now, the events I create in Outlook for Mac, appear in my iCal as locally saved instead of showing up as iCloud enabled. Solution--Go into iCal, open the event, and switch the category to an iCloud-enabled calendar (requires 2 clicks per event). Obviously this is a work-around, and not a true solution. My guess is that Microsoft will need to release a patch for Outlook for Mac that allows "Sync Services" to push to iCloud.

I have been frustrated and stressed for over a week and take some confort that lots of people are having similar problems! My issue is that I have MS-Small Business Server 2008. Up until last week I had iPhone 4S, iPad2, MacAir 2011 and MacMini 2013 all syncing Mail, Contacts, Reminders and Calendar to the Exchange account. Couple of weeks ago Calendar on my iphone went blank, lost all and not syncing, everything else still syncs perfectly, even Mail, Reminder and Contacts on the phone. Took it to Apple, they upgraded ios6 to ios7 and even gave me a new 4S in case it was hardware but nothing worked. There have been no changes to my work server in that period, but I did subscribe to Office 365 on MacMini and set up syncing on the Outlook there (worked fine).

I have tried deleting and adding Exchange account on phone several times. I'm sure all my account information is correct, using server "remote.whatever" which is the same as on the other Apple devices.Also tried most of the ideas in this thread that seemd to relate to MS-SBS/Exchange to no avail.

Apple now say they have no idea, maybe a network or server issue?

Any ideas?

Oh, just to add, I also tried adding my account to my partner's iphone, same deal where Mail etc syncs but not calendar!

And something weird - if I get an invite and accept as an email, it appears! Is it something to do with the Mail-Calendar combo?

I had the same problem when I upgraded my iPhone 5 to iOS 7. But my iPad 1 on iOS 5 continued to work. I fiddled with it for about a week, adding events, modifying events, deleting events, etc. but nothing changed.

On my iPhone I went into the settings, Mail, Contacts, Calendars, selected my Exchange account, ensured everything was turned on, selected Mail Days to Sync. It was set to 3 days. I changed it to a month. Things then started to sync on the Calendar immediately.

I guess changing that setting must has "cleaned out the cobwebs" or something. No problems since then.

Ryner99 just tried your suggestion, but no luck. Our IT guy at work will have a look today at the Server settings, and I'll let everyone know if that helps.

OK in my case our IT guy at work was able to resolve. It seems that my account in the Exchange Server had 6MB of calendar information when the archives were restored as part of a clearing exercise, and the iPhone could not cope with downloading so much. He archived and deleted until about 2MB left and everything synced perfectly.
