iOS 7 calendar is not syncing with Exchange

I have the same problem in my iPad2. Weird thing is, I also updated my iPhone 4S to ios7 and there everything works fine. With the same agendas.

I am having the same issue. I am planning to go to Apple store for help as I have been unable to fix it for 3 days.

Possible solution:

Here was my situation and how I solved it...

Exchange 2013 on back end. iPhone5 w/ iOS7.

email and contacts were syncing, but not calendar.

Discovered that the email address used in Exchange was _case sensitive_ when setting up ActiveSync on the iPhone.

When setting up ActiveSync on the phone, make sure that you use proper case when spelling out usernames and email addresses. For example: flast@abc.com is NOT the same as FLast@abc.com.

At least this is what worked for me. Getting all the case correct allowed the calendar to start sync'ing.

I hope this can help someone else out.

Jepp this solved it for me,ty!

Had the same issue on my iPhone 4 and iPhone 5 syncing to an exchange server. Email and contacts worked fine, calendar nothing. Went to mail settings - Exchange, turned the calendar off, confirmed that I wanted to delete all existing events (there weren't any anyways) and then turned calendar back on and low and behold it is working on both phones.

I had problems with my exchange account, that I'm sharing with my girlfriend. and with my mail constantly saying it couldn't recieve mail - eventhough it actually did.

I searched the net, and it seems that google is responsible for the problems...

this helped me and I hope it will help some of you as well:

I have a similar problem.

Updated ios 7 on all my devices (iphone 4 and mini ipad), using mac calendar but was not sycning on icloud.

now the calendars on my mac are not syncing with my devices properly -- some are bieng duplicated on the devices, other events are just plain changed.

any and all help welcome.

I recycled my account, meaning I deleted it from 'Settings > Mail, Contacts, Calendars > Accounts' and re-added it. That worked.

Before, when I looked at that account it only had options for Mail and Notes, neither of which I wanted. No option for Calendar. When I recycled my account, the other options appeared, including Calendar.

It took a bit to sync, but now it works.

Editorial: It's pretty lame on Apple's part that this needs to be done. Actually, that's a really poor upgrade. What else does not work? If the code I worked on did that kind of nonsense, I'd get in trouble with my boss (and he'd be right to be mad).

I have exactly the same issue. I can view my Google calendar, and any changes I make to the calendar from my MBP pro are reflected on the phone. But I can't add anything. When I do they are there for just a few seconds and then disappear. It's almost as if the server calendar is overwriting the phone calendar

i deleted all my calendars on ical and icloud, however in itunes the old calendars still appear and if selected will sync with old data.

new calendars i create do not appear on the list of calendars to sync with.

HELP! AM LOST WITHOUT MY CALENDARS!

Thanks to all of you for your prior postings, I did try all of your solutions for a co-worker with a 5s iPhone and iOS 7.0.2. He couldn't get any Calendar data for one of our Google Calendars. We tried via Exchange and via Gmail etc. We recreated the account from scratch as Gmail. Then, we did this:

Log into your Gmail account on a computer, go to

http://www.google.com/calendar/iphoneselect

then check the checkbox for the calendar in question. The update started immediately.

This is in response to Buiz:

Go into your calendar and at the bottom of the screen it will say "today" "calendars" "inbox". Click calendars. Make sure that under "On My iPhone" there is a check mark next to "Calendar". If not, click it and you will be good to go.

I've done all the things mentioned here by any user and still my multiple google calendars are not syncing to my iPad, though they were there before the ios update. Has anyone discovered other secrets to getting the caldav route to work? I am so frustrated!

Me too. Have you found a way to make it work yet? I haven't, though I've tried every suggestion here.

I deleted my account info on my iPhone, then re-added it as Gmail (not as Exchange). This worked for me, but I also followed the steps here, especially the "Sync Multiple Calendars" instructions:
