Since upgrading to iOS7 many Outlook contacts addresses do no sync to my iPhone 4S.

Well, if it is a bug, it is not affecting my 4S, my daughter's 4S, my wife's 4, or my son's 5. Again, I'm not thinking it has to do with the phone software, since it is only a single field that is having a problem. Did you attempt anything else I posted?

That is truly strange, as the phone should be able to sync and handle more than one address and should not require this workaround. Buy, for right now if it is working and you have it figured out, I wouldn't mess with your solution. Good luck.

Just out of curiosity. Those contacts created in Outlook or something else? What happens if you delete the address, close the contact, then go back into the contact and type the address over again? Does it sync then?

Sorry, but I have run out of ideas. I wish I could do more, but I have provided you with everything I know, and then some I think. Good luck.

The exact same thing has happened to me. I have an iPhone 5 which is now running ios7. I sync my contacts using iTunes with my contacts in a Mac contacts DB. I discovered today (at the post office where I was trying to mail a package to someone - 😠) that most of my contacts have the addresses missing. The addresses are still correct on my Mac, but they are not syncing over to the phone. Phone numbers and email addresses seem to be OK. It's just the addresses. If I have both a work and a home address, only one has synced - for some it is home, for others it is work. Most of my contacts have only one address, and that is now missing on the phone.

I also have a 1st gen iPad, which is running ios5. I sync that to my Mac as well, and the contacts are syncing over just fine.

So I conclude (as did tsaainta) that this is an ios7 bug.

I would be a little more convinced to accept that if the two of you were using the same program, but you aren't. You are using a Mac database, and tsaaainta is using Outlook. I find it hard to digest that two completely different apps on different platforms would exhibit the same action. A true bug would not affect things in this fashion.

I'm surprised that you would draw that conclusion. I come to the opposite conclusion.

tsaainta syncs Outlook contacts to iPhone with no issues until upgrading to iOS7. Wendy syncs Mac contacts to iPhone with no issues until upgrading to iOS7. The common denominator is iOS7. You are correct that we use "two completely different apps on different platforms" and those apps on those platforms are NOT having the problem. The common one (the iPhone with iOS7) is where the problem occurs.

Also, remember that my iPad - which I cannot upgrade to iOS7 because it is a 1st gen platform - is still syncing properly, the way my iPhone did until the iOS 7 upgrade.

tsaainta, for what it's worth, I now have it fixed, although I'm not sure if it will work for you. I found another post about the same issue here: https://discussions.apple.com/thread/5358170?answerId=23163486022#23163486022&ac_cid=tw123456#23163486

Even though I have been syncing with iTunes, I set up iCloud to try that. Same issue with missing the addresses. So I followed the advice of the other poster and removed all the contacts from iCloud and did a re-sync. They came over correctly now, with the addresses.

Also, just because I didn't want iCloud to have my contacts, I un-did the iCloud and went back to the iTunes sync and it now works fine for me.)

Good luck.

While I agree that iOS is a common denominator, the method used for syncing is different. I'm glad to read in the other post that you got it corrected. You did not indicate that you were using iCloud (at least I don't remember that) in the earlier post, and I'm not sure if tsaainta did either. That could have been a common denominator as well.

Good to see that it works, and I'm saving the conversation to linked in case someone else reports this problem. Great find on your part.

Chris, count me in as another person who started having this problem only after upgrading to iOS7. And, like tsaainta, I am using Outlook, but with an iPhone5. New contacts created in Outlook after the upgrade will sync completely, but those created before leave the address field empty. And I believe WendyRobin had the problem before she starting attempting to solve it with iCloud, so we can't factor iCloud into causing the problem. WendyRobin, were you able to resolve the problem without using iCloud? I too am not interesting in having all my contacts into iCloud. Thanks.
