Problem to Sync Calendar in iPhone to Outlook

I have an issue with syncing iPhone calendar to Outlook calendar since I upgraded to iOS7.
I have noticed since the upgrade, entries that I made into iPhone calendar will since to Outlook calendar but any subsequent changes of the entry that I made into the Outlook calendar will not sync back into my iPhone.
I didn't have these issue with the iOS5. I am using iPhone 4 and Microsoft Office Outlook 2007.
Can someone please help me? Any ideas?
Thanks.

Outlook 2002 is not officially supported by Apple for iPhone syncing.
Only 2003 SP2 and 2007.
There are threads here with workarounds if you search. No promise they will work for you, however.

Error while merging data problem while syncing calendars to iPhone

My iTunes just recently updated itself to iTunes 12, I'm using OS X Mavericks on a Macbook Pro, and have an iPhone 5S with iOS 8.1.1.
Whenever I try to sync my calendars from my laptop onto my phone, I get a message saying "iTunes cannot sync calendars to iPhone because an error occurred while merging data". I'm not sure if it's an issue with iTunes or my phone...but everything else syncs normally.
If anyone could help it would be greatly appreciated!!

hi there,
i've found a great & simple solution for this problem
just open your iCloud acc on iPhone
turn off calendars (it wil ask you to keep info or not - KEEP IT!)
and turn back on (MERGE!)
now SYNC it..
and that's it
PS in my case it was contacts so the procedure is the same..

Problems with synching calendars between iPhone and Outlook 2007 on Windows

I recently purchased a copy of windows 7 ultimate 64. It was an English version, but since it is ultimate I downloaded and changed it to Danish - so far so good...
I have synch'ed between outlook and iPhone on a Vista platform without problems, but now on windows 7 when I sync - the result is, that on my iPhone the meetings, work schedules and birthdays I have in my calendar is shown a day too soon!!
I have checked that both iPhone and Outlook start the week on Mondays, so that is not an issue - I have updated my iPhone to the newest software with out any luck - so now I try and write here instead - hopefully someone can help me...
thanks in advance

yes they were set to the same timezone - which puzzled me a lot...
I lost a lot of sleep, but I can now say that I have solved the problem...
What I did was, that I un-installed microsoft office (desperate I know!) - then ran a sync with the iPhone choosing to overwrite the Calendar in the phone - as there was no calendar present - it deleted what was on the phone. Then I re-installed Microsoft office, by doing that, I didn't loose anything because the user files was still present including mail setting etc. - resynced the iPhone - and now it works...
Just can't figure out what went wrong in the first place...
thank you for your answer

ITunes could not sync calendars to iPhone because the iPhone disconnected

error message
iTunes could not sync calendars to iPhone because the iPhone disconnected
I have spoken to Apple a couple of times in the last week (approx 2hr) apple support said it could be a Microsoft issue I have spoken to Microsoft and read endless information from the net and it seems that Microsoft is not the issue.
I have uninstalled itunes and reinstalled, reset all settings in Settings\General on the phone, reset sync history on the iPhone, upgraded microsoft office 2003 to 2007 and I am still getting the error message.
I have a iPhone 3G, pc is running windows 7 and just upgraded to microsoft office Home and Student 2007 and Office Outlook 2007.
iTunes version 11.0.2.26
iPhone iOS 6.1.3
I have the same error on my wife's iPhone as well.
Any help would be great.

Thanks midwestcraft. I had this problem and your answer solved it for me.
Thought this further info may be of use to some who wants more historic dates in their calendar.
I had "do not sync events older than" unchecked and the input field set to "0". When I changed it to 180, it worked perfectly. I've found that I can increase this number to "545" - anything higher causes the error. This seems to coincide with some strange multiple-entry events in my calendar.
Don't know if this will be a clue for somebody to fix the issue.

Syncing Calendar Mac/iPhone

I'm having problems syncing my Calendar on the iPhone with my Mac, which doesn't have anything in it, using the latest version of iTunes. I have the latter set just to sync my Calendar, and I have unchecked Calendars in the Advanced settings so that the Calendar on my iPhone is not overwritten.
Having read some other contributions here I opened up the iSync settings and reset sync history. Having done that both iTunes and the iPhone show that the sync is in progress but after leaving it on for an hour it still hasn't finished. If I stop it there and look at iCal there's nothing there at all - I would have thought that it would have shown what was transferred already.
The odd thing is that although I have set MobileMe not to push up data, as soon as I start the syncing through iTunes the little icon in the menu bar showing the MobileMe status starts spinning indicating that it is syncing. If I go to the MobileMe preferences, uncheck the 'Show status in menu bar' and then check it again it stops spinning, with both iTunes and the iPhone still showing that sync is in progress.
Is this a bug or have I not correctly stopped the MobileMe syncing, and why is the iTunes sync taking so long?

If you are accessing your MobileMe account with your iPhone, do you have Calendars on for over the air syncing with your MobileMe account settings on your iPhone?
If you are syncing calendar events direct with Outlook via the iTunes sync process, you don't have over the air syncing enabled with Calendars on your iPhone. You can sync calendar events direct with a supported application on your computer, or over the air with your MM account. You can't do both at the same time.
What do you have selected below Calendars under the Info tab for your iPhone sync preferences with iTunes on your Mac?

3. Then click the button to reset sync history.
4. Now click ok to close the preferences window.
5. connect the iphone to itunes and go to the info tab.

ITunes 8.1 won't sync calendars to iPhone for me

I just installed iTunes 8.1(50) and am trying to synch my iPhone. It appears to synch everything except for calendars. After synching is completed, iTunes displays an alert saying: "iTunes could not sync calendars to iPhone 'Darrin's iPhone' because an error occurred while sending data from the iPhone." I have iPhone OS 2.2.1 installed. My console logs show this problem when the calendar sync fails:

It solved my problem. My calendars sync fine now. Try it.

Syncing calendars to iphone

Recently my calendar will not sync to my iphone. I put it in the dock and then I get the message in itunes saying " syncing calendars with iphone" but the process never gets completed. It stays like this for hours. I have even left it overnight and it still was syncing in the morning. I don't have a large amount of calendar entries either. I tried restoring my iphone and that did not work either.
Any suggestions??

I had a similar problem a while back and someone here helped me through it. That's the good news. The bad news is I don't know who and I don't remember what they said exactly. It was something to the effect of going into iTunes and checking a box to synch calendars. This basically purged my events in the phone and forced a synch of my PC events to the phone. It worked. I believe it was under, as in scroll down, mail items. Play around with that and hopefully the person who helped me will show up again. Good Luck. I know how frustrating this can be.

How does one do a two way contacts sync between an iphone and outlook? Most of the community has answered as this to be "always so", but it does not work! Changes made on outlook get done in my iPhone, but it does not work the other way around!

Since I down loaded Mavericks I can't sync calendars with iPhone. How can I sync iPhone calendar and Mac calendar

Since I downloaded Mavericks on my Mac I can't sync calendars with iphone. How can I sync iphone calendars with Mac calendar?

Mavericks syncs Calendar via iCloud.
Make sure you have the same iCloud account set up on your mac and your iPhone.
In System Preferences > iCloud, make sure the Calendars checkbox is checked.
In System Preferences > Internet Accounts, iCloud should be an account in the box on the left, and Calendars should be checked in the box on the right. If you have other calendars, for example, from work, make sure those are enabled too.
Check the same settings on your iPhone: in Settings > iCloud, make sure the same iCloud account info is present and that the Calendars slider is on. in Settings > Mail, Contacts, Calendars, make sure the iCloud account is present, and that the Calendars slider is on.

Recent problem with syncing calendar items created on iPhone

For a couple of months I had iPhone/Outlook syncing working well, but just recently I noticed that new calendar items created on my PC sync to my iPhone, but calendar items created (or changed) on my iPhone do not appear in my Outlook calendar. I seem to still be able to create contacts on my iPhone and have them appear in Outlook, so this problem is restricted to calendar entries. Since this is recent and there were also recent iTunes/iPhones updates, I am guessing that they are related to this new problem. Has anyone seen anything similar and does anyone have a suggestion?

I am also having issues with Calendar items after the latest patch. It seems that recently added appointments to Outlook 2003 do not replicate to the iPhone. My recurring appointments are fine and I have 3 conflicts which I have reconciled 4-5 times now.
I have repaired my .pst, I have removed my sync point on the iPhone twice.. nothing works!

Problem with updating calendar in Windows 7 Outlook with calendar in iPhone.

Initially, I thought that I was able to enter events in Outlook within my Windows 7 desktop and they would appear thru iCloud in my iPhone 4S. Now the iPhone calendar will not update itself with Outlook calendar events. I have tried a hard sync with my iPhone thru my desktops' iTunes, but that does not seem to have had any effect.

Try installing the Cirrus driver from the BootCamp 4.0.4326 download:
http://support.apple.com/kb/DL1636
BootCamp/Drivers/Cirrus
I read various things saying I should install the RealTek driver, but this didn't do me any good. Two seconds after running the CirrusAudio32.exe, my speakers came to life. Now Windows is dinging, chirping, and all that.
This is on a MacBook Air A1369.

I am getting a sync error between iphone and Outlook 2007: ITunes could not sync calendars to the iphone because the sync server failed to sync the iphone. How can I fix this?

I have the "sync calendars" checked.
This happens about every three months and drives me crazy!
I have a 2G iphone on T-Mobile.

i use outlook for my work email, but my personal email is in gmail. besides work email, i do not use outlook at all.
i get my work email on my iPhone, but i do not sync calendars and contacts as i have to use an imap connection for work, and this does not allow for calendar or contact syncing.
i have seen a gmail/outlook sync tool, but i am afraid i do not use it so i can not offer any help with it.
