You have to make a choice if you happen to use Outlook. Using iCloud contacts means not using Outlook contacts. If you try to blend them, then iTunes will report Mingler errors. <br />
<br />
So I use Outlook exclusively and turn iCloud contacts OFF as you have shown.
</div>


<div>
It will merge your iPhones contacts ( contacts on your Phone ) with your saved contacts on iCloud. if you have already saved your contacts on ICloud &nbsp;then they will duplicate on ICloud.
</div>


<div>
That and the iTunes error is why I keep it turned off
</div>


<div>
I see that Natty says it will not merge, but if it will, is there any other option to delete these &quot;duplicity&quot; other than &nbsp;manually deleting one-by-one?<br />
<br />
Also, if switched ON, it will sync all Contacts, Calendars, Reminders and Safari with iCloud and in return we will have all our info sync &nbsp;with all devices that have these switches on? Correct?
</div>


<div>
When you say syncing stops, you mean if checked ON, and we modify a Contact in our iPhone, then Outlook and the other devices will not sync?
</div>


<div>
I tried the iCloud system and the Contacts stopped syncing with Outlook. You need to pick one main host system you like and sync with that.

We are assuming the &quot;yes&quot; is for the second part, <i>&quot;...it will sync all Contacts, Calendars, Reminders and Safari with iCloud and in return we will have all our info sync &nbsp;with all devices</i>&quot;. &nbsp;As for the first, is there an option to delete these &quot;duplicity&quot;, are there?

<div>
Thanks and good luck. &nbsp;Happy to help.

Chose our entry as &quot;Best&quot; because it has the actual step-by-step to assure syncing.<br />
<br />
Thanx all!

Hi,

We where checking our iPhone 7 plus iOS 10.3.1 settings and noticed that Contacts, Calendars, Reminders and Safari are checked off (see pix below)



What happens if we switched On? (in Contacts requests confirm "merge").

iCloud options Contacts, Calendars, Reminders and SafarI in iPhone 7 iOS 10.3.1

The iPhone is a smartphone made by Apple Inc. It and the iPad, along with several other mobile devices from Apple, run on the iOS operating system, which has its own topic, as does the iPad for device-specific questions. Native iOS applications are written in Objective-C or in Swift using the Cocoa Touch frameworks or HTML5 compiled with the help of a package manager such as Adobe PhoneGap; a common IDE is Xcode.

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.
