IOS 6.1.3 and Exchange Calendar Sync issues

I have a staff member in our association who has recently upgraded to IOS 6.1.3 on her iPhone and ever since, whenever she creates an event on her iPhone calendar that is synced with her work Exchange account, it will appear on Outlook on her computer, as its supposed to, but moments later it will disappear from her phone and I can't get it to reappear. Any thoughts?

Same issue here Sam, with several users in our organization of about 2500 iPhone and iPad users, mostly iPhone.
I have been watching your post for over two weeks now and no one has responded. Have you learned anything in the interim?
Unfortunately I have not, my many searches across the web have yielded no results that are relevant to the problem.

IOS 6 and Exchange Calendar Sync Issues

My company has been having several issues with iOS6 active sync and Exchange 2010 (sp2 ru4 v2).
Issues:
1. When an appointment is updated by the organizer the initial appointment does not update on the iOS device. Instead a 2nd appointment is created at the new time causing both appointments to be present.
2. When an appointment is updated by the organizer the iOS device does not reflect the updated date / time. This seems to happen more than not with recurring events.
Does anyone know if apple is aware or what the procedure would be for me to open a case with them directlty? All iOS devices are fully updated (to avoid the tansaction log bug that was happening).

Exchange calendar sync issues among iOS devices and Mavericks

When I add an event to a shared Exchange calendar on my Mac in iCal, and mark it as All-Day, that designation does not appear with the event on my iOS devices. Instead, it's given a 24-hour duration from 12 to 12, so to speak. Here's the confusing part: If I edit the event on my iPhone to correct it as All-Day, it does not sync that All-Day designation to my iPad. Additionally, if I then make the same correction on the iPad, toggles it on the phone and removes All-Day. Removal of All-Day designation on a device does remove it on the Mac calendar, which I then have to change back. So I chase it around in a circle and end up with the correct duration on only one iOS device. The difference in All-Day and 24 hours duration does matter graphically as many of these events run for several weeks or months. All-Day keeps them confined to the upper section of the calendar graph rather than muddying up the lowerm hourly appointments.
Any ideas on how to rectify the problem?
I'm running Mavericks, iOS 7.0.3 and using MS Exchange 2010.

There are several other posters on the Forums that are having issues with Exchange sync'ing with Mavericks. It could be that your all-day verses mutli-hour issue may be among them.
Most of the problems that people are seeing, including myself, are more to do with Mail and Calendar simply not synchronizing.
My Mail.app INBOX for my Exchange server is now several hours behind my iOS and Windows Outlook instances. Calendar appointments are simply not being pushed to the server (though they seem to be retrieved OK).
So, sorry for now help on this one directly, but you are not alone.

Microsoft exchange calendar sync issue in iOS 5.0.1

Hi,
I have iPhone 4 with iOS 5.0.1 installed. My company uses Miycrosoft Exchange Server and I have synched my iPhone using the Microsoft Exchange server account option. I don't have any probelm with my emails or contacts.
However, the calendar is not synching properly. After I setup the account for the first time, I see many of my calendar items has been synced. But some of them are missing. I can't find any reason why those items are missing. I added/deleted new items on my calendar on Outlook Web Access and it showed up on my iPhone. I also tried adding/deleting items on my iPhone and they synched appropriately. The only issue is some of the pre-existing items are not showin on my iPhone and I can't find any reason for it.
I already tried to delete the account and add from scratch. I also removed the iCloud from my iPhone and tested without iCloud, no difference. I reinstalled the iCloud.
Any help is much appreciated.

We have struggled with this as well on Exchange 2010. We just trued this today with some of our users and seems to get everything back into sync:
On the iOS device:
• Navigate to Settings app > Mail, Contacts, Calendar.
• Scroll down and locate the Calendar section
• Tap Sync (under the Calendars section)
• Set the interval to All Events
• Close the Settings app (Tap Home button)
I suggest rebooting the iOS device. Check the calendar and let it sync – look for those missing events.
This has worked for everyone that had the missing events issue.

IPhone to Exchange calendar sync issues

OK, I have read through many posts on here, but have yet to find a post that describes my situation. If someone has seen this answered in other places, please let me know.
I currently have the following setup:
iPhone 2.2.1, using OTA sync with Exchange
Entourage 2008 (not Outlook/Windows)
Exchange server 2007 (at work, I am not the guy who runs it)
My mail and contacts work fine.
CALENDAR issue for me is something I can't quite wrap my head around:
I get syncs fine for calendar when accepted through Entourage - but when they are updated by the original senders I get multiple entries for every event showing up on my phone (the old events aren't removed). In addition, my phone does not sync back to the Exchange server when I accept invitations, nor when I create entries in my calendar.
Thoughts?

This problem is only something I've had problems with recently. Previously entries in the Calendar would sync OK regardless of where they were created or accepted. So appointments I logged on the road into the phone would work back into Exchange and onto Entourage.
Two things have changed. Our Exchange server was upgraded and how has Active Sync which means I now get push notifications which is great. I've also gone up to the 3.01 software on the iPhone.
Now, it seems I am ONLY getting push from Exchange to the iPhone. Calendar entries from Entourage appear on the phone.
Any calendar entries created on the phone or invites accepted on the phone stay on the phone. They are not synced back to Exchange and onto my Entourage calendar.
As someone who is office based for only a few days a month, effective Calendar sync is vital.
If the problem is with the OS update on the phone then this fix needs to be part of 3.02. If the problem lies with the Active Sync setup then I need some instructions to go back to our Sys Admins with.
Thanks!

Outlook and iPhone Calendar Sync Issue

I’m having an issue where any meeting on my Outlook calendar that is after 3AM and spans multiple days (i.e meeting is from Sunday 4AM to Monday 6PM) it actually shows up on my phone as being Monday-Tuesday instead of Sunday-Monday.
Has anyone else seen this?

We have had this same issue on the older through to the latest os. I dont know whether the issue is the iphone diary or outlook.
We have 2 phones syncing to one outlook account. If I put in an all day event on my iphone when it syncs to outlook it spans 2 days and then when synced back to the phone it honors this, so suddenly I have no idea which day the event is on.

Exchange 2010 and iphone calendar sync issues

Hey,
I know this question has been asked plenty of times before and just need a straight resolution. We have just migrated our environment to Exchange 2010 and the major issue is that when an event is created in Outlook 2011 it is not always showing up on their iphone and also vis versa. Is their a resolution to this problem so I can implement it in an emergency change. Thank you for all your help!

Here let me explain the scenario again any user who logs in to exchange from outlook working fine password not expired and he has iphone active sync working no issues , now while all devices are working when he starts his ipad after a week or so when he
opens his email on ipad it prompts the password on ipad and same time on iPhone , he does not want to enter the password and wants a technical justification , I told the user something to do with Exchange 2010 sp2 and ios 7 ,but that is invalid justification
. if you have any other valid justification please let me know. or a solution to this issue. user wants to login without any password prompt while the password is saved in device and not expired , is there any feature in Exchange 2010 sp2 that would recognize
how many days device has not logged it and would force to enter the password.

IPhone 2.0 exchange calendar sync issue with PUSH enabled

I have setup Push sync over Exchange for my iPhone. If I accept an incoming meeting request it does not update Entourage calendar. If I change delivery setting to fetch, the issue disappears. Is this a known bug? BTW - several of my work colleagues have noted the same issue. All are Entourage users too.

You can accept/decline/mark tentative any meetings sent to you, and you can also edit meetings you create (whether on the phone or in Outlook, OWA, etc).
IMPORTANT: make sure your user name for the Exchange account as entered on your iPhone exactly matches the case of the user name set up on the Exchange server. (Settings > Mail, Contacts, Calendars > Your-Exchange-Account > Account Info). Set both the Email and Username fields to exactly match the case of your email and username on Exchange. Look up yourself in the Exchange Address Book in Outlook and see how it's entered. i.e. [email protected] must be entered in the iPhone with the same capitalization. I also edited my own contact cards to match -- just to be sure.
Otherwise, the iPhone gets confused with meeting invites and might ask you to Accept/Maybe/Decline your own meetings! If this is the case, you also won't be able to edit meetings on the iPhone even if you create them.
As far as i know, the above is only true for Exchange accounts. I had this problem, and solved it last night.

Exchange Calendar Sync Issues List

I have noticed three things that are driving me insane and wonder if anyone else is having the same problems and/or has found a fix for the problems below.
1. If you add an appointment in Outlook with categories, by editing it with the iPhone in any way, it clears the categories every time consistently. This is a huge issue for us!
2. You cannot add a private appointment from the iPhone
3. You cannot change the view in the calendar on the iPhone. The default view is to see all the appointments in 30 minute increments, I need this to be in 15 minute increments.
Anyone else what to add to the list? I figured we can list it all here so that Apple has a reference to see some of the issues we are having.
Thanks,
Zach

Hmm, i jut bought an iPhone 3g and imust say it has not impressed me with regards to its Exchange capabilities. some of my dissatisfaction are as follows:
- cannot customise calendar, sms , alarm sounds. the default sounds are just too soft and short and i have missed a couple of my appointments. Plus, there is no blinking light to tell u if u have a missed call, sms or appointment/reminder, sigh...
- the contacts in iphone are also not very smart. u have to key in your telephone no. together with the + and country code, else, when u receive a ring/sms, it will not show u the person from your contacts but merely a number;
- i can't load any of my mp3 songs as my ringtone or my calendar or my sms alerts as Apple specifies the ringtone has to be <30 seconds and no customisation for sms/reminders...sigh...;
- also, if i open up any office documents >1mb, my iphone crashes or simply doesnt open them;
- i share some of my calendar with my staff. In my previous Sony Ericsson P990i, when i enter an appointment, i could mark personal appointment/reminders as "private". iphone doesnt allow me to do so hence, the whole world knows my appointment...sigh..;
- iphone doesnt allow u to sync with microsoft outlook notes...sigh...
i sincerely hope there will be a new update from apple to address all these issues if it wants to attract the business market...

E60 Mail for Exchange Calendar Sync Issues

Hello all,
I'm able to sync my email, calendar and my contacts. However I've noticed that some of my calendar items have not been sync'd.
For instance, I might have A, B, C, D as appointments in the same day and in that order. I'll only have appointments A, C, D display on my E60.
Before anyone asks, I don't get any error messages and yes, I've checked the logs on the handset.
Any ideas?
Cheers, Krish.

Hi,
I uninstalled the last release of MfE. I reinstalled an old version (2.05.003) and it worked immediately ! So many people are spending so much time with the last release trying to sync calendar... :-(

Longstanding Exchange Calendar Sync Bug Persists in iOS 7 / 7.0.2

For those who sync their iPhone / iPad / iPod touch to a Microsoft Exchange e-mail environment, you may be aware that there's a longstanding Exchange Calendar Sync bug (affecting iOS 4.x - 6.1.3). An otherwise functional iDevice may suddenly remain warmer to the touch than normal, exhibit much shorter battery life, and start using cellular data at up to ten times the user's typical pattern. I've taked with Apple Support several times, and was never able to get an answer. The fix involves simply opening the Exchange account settings on the iDevice, shutting off calendar sync for thirty seconds, and turning it back on. This is nothing new.
Over the weekend, an executive’s iPhone 5 (on Verizon) and his iPad 2 (Wi-Fi only), both running iOS 7, began exhibiting runaway connections to my employer’s Microsoft Exchange ActiveSync server. The user upgraded his iPhone 5 to iOS 7.0.2 over the weekend, but the problem persisted. In one 24-hour period, his iPhone checked in with our server 45,009 times, while his iPad connected 55,547 times. Normally we’d expect to see a single device connect a few hundred times per day rather than tens of thousands.
I've written more about it here.

This is still a problem in iOS 7.0.4 as well. We just had runaway calendar sync behavior on a 4th generation iPad running iOS 7.0.4 (iPad3C4/1102.55400001), which connected 75,436 times in a single 24-hour day.

HT4528 Is there a fix for calendar sync issues between iPhone 4S and Outlook?

My boss has an iPhone 4S running iOS 6.0.1 and a Microsoft Exchange 2003 email account and has consisent sync issues with her calendar. The problem only seems to come up with calendar invitations. Usually, when people send her calendar invitations the events get added to her Outlook calendar on her PC but not on her iPhone. More recently she also sent out invitations through Outlook that also didn't appear on her phone. She has also accepted invitations on her phone that did not appear on her PC. The problem seems to have gotten worse more recently.
Does anyone know of a way to fix this? I tried deleting the calendar through the phone's settings and re-installed it but it didn't solve the issue.

There was a reported issue with Exchange and iOS with re-occuring meeting invites. Not only did it cause issues on the device, but on the Exchange server side it created huge logs and high utilization on the CAS. This was an issue on iOS 6.0.x - 6.1.3 (at which time it has been fixed from 6.1.3 on). This was attributed to the iOS version and happened on all devices (not just the 4s).
I am not sure if this is what your employee is experiencing or not - but this is one that we had, and we asked all running iOS 6 to upgrade to the most current release (oddly enough, we did not see this in iOS 5.x devices).

Looking for exchange calendar sync groupcal *****

Looking for exchange calendar sync system to replace sucky groupcal.
I've had nothing but problems with it. I get duplicate calendars, duplicate calendar entries, and the daemon stops updating from the
then the support folks are threatening to cut off support and no longer help me to fix their broken code!
I wasted money and so much time on this app, is there anything else out there that does a better job?

Not to mention that it doesn't work with Leopard now! I wish there was a way to get my Exchange calendar to sync to a third party that would sync with iCal 3.0. Since there is not support for CalDAV it would be nice if Exchange would support this!

IPhone battery issue - exchange calendar sync the primary suspect

I previously posted about very poor battery life and how a full re-install and reset seemed to fix the issue. The battery life was great for a week or so then I tried to go from my calendar on .me to my calendar on exchange. Then the issues re-appeared.
I am 99.9% sure that calendar sync via exchange is the issue. I am not sure if it's a funky server setting that my company has or what. It seems to work fine for others in the company however my e-mail account at work is relatively old compared to theirs. I am also on a Mac using Entourage. I made sure push was turned off and only fetch every hour. Still the same issue.
Again there is no battery drain when synching via iCal/.me. This kind of defeats the purpose of push calendar for me because I need to synch Entourage with iCal then iCal with .me. This means I need to be on my company network to sync. So the only time my calendar syncs is when I have my laptop on the company network.
The reason I'm writing is in hopes that someone from apple reads this and posts a fix. The CPU gets noticeably hot when exchange calendar sync is on so I know something is up. If you have any more info on this please let me know. I am also going to try the apple store tomorrow. Maybe it's a defective phone BUT since it works for everything except Exchange cal sync I am thinking it is some server/client polling issue.

I KNOW THIS IS lONG, BUT PLEASE TAKE THE TIME TO READ IT.
OK - After about 5 hours of troubleshooting I have FIGURED out why my battery was lasting only 3.5 hours. I hope this helps.
1. completely wiped the phone away and brought it back with push disabled. EVERYTHING FINE
2. I enabled push waited 1 hour. EVERYTHING FINE
3. I enabled mail push syncing. EVERYTHING FINE
4. I enabled contacts push syncing. EVERYTHING FINE
5. I enabled calendar and BAM battery starting spinning in overdrive. The calendar was the issue.
6. I disabled push and to my surprise it did not get better, only after a reboot did the batter return to normal. OK - so I have narrowed it down to the calendar.
7. I am using Outlook 2007 with Exchange 2003.
8. I took a bold step and archived my entire calendar to a pst file so it left nothing in the calendar.
9. Again to my surprise the battery started draining immediately when i enabled the calendar again. On a hunch I checked the properties of the calendar and it said there was a few kb left. I could not do anything to find these.
10. I logged into Outlook web access (http://exchangeservername/exchange - if enabled) and did a search on the calendar and it found two orphan calendar entires. I deleted them.
11. I enabled calendar syncing again and it went perfect. I then copied back all of my calendar entires from the archive pst to the calendar and luckily no problem.
The push service must have not known how to process these two entires and was just chocking on it. For the last two weeks I have been getting 12-14 hours from a charge with 3-5 hours of use. Farb better then the 3.5 hours with no usage. I hope this helps!!

Local Calendar and Exchange Calendar

I have a Local calendar and Exchange calendar in iCal. I don't really need the local calendar, is it OK to delete it?
The reason I don't want the Local calendar is that some appointments come through on the Local calendar and cannot be moved to the Exchange calendar. This means they aren't synced to my iPhone.
Thank you,
Rod

If you don't need the local iCal calendar, simply delete it. There's nothing wrong with only using the Exchange calendar.
