Outlook for iOS + Caller Identification

Steel Contributor

Hey folks,


i'm struggling at this for years, as you can see in my previus post from 2020.

Let me shorten this:



  • We have iOS Devices with Outlook for iOS installed.
  • The users have many contacts in their EXO Mailboxes
  • When a user gets a call from one of his contacts, the phone number is presented instead of the name (no Caller identification)


  • I already know this MS articles belonging to Contact Sync.
    • So i've learned that this leads to a running contact sync without the need of an icloud Account. The contacts could be written directly between Outlook for iOS and the native contacts app. (Better than nothing :xd: )
  • The Problem is, that if contact sync is in use ANY App could see these contacts. (Including Whatsapp, etc...)
  • Because of GDPR this is a no-brainer.
  • Many other solutions are using Apple Call-Kit, so that the incoming call is identified (name is shown) just without any need of contacts to be present in the native contact app.

I didn't found anything belonging Call-Kit or any other possible solution for this issue, yet.


There MUST be any better solutions except syncronizing all the contacts, isn't it?

ANY Answer is highly appreciated. (At least the positive ones :xd:)

I've seen that you posted in a comment in 2019 that there is no current plan to support CallKit.

There were many other threads back in the days where users were talking about caller identification. (example). I've already read the whole posts and comments on this. :sad:

Any ideas, how european customers can handle this properly?

Hi @PatrickF11 


Confirming your findings!

As you/articles explained this is a limitation, it cannot be done without dual syncing.


You have only way to achieve a workaround to the issue which creating a native app profile and then sync contacts only. (Exchange ActiveSync). 



@Moe_Kinani Thanks for your thoughts.

This approach is not acceptable, because we're using Conditonal Access Rules only allowing Exchange via Outlook (only via app protected apps). But we deliberately don't want to change that. :xd:


Are there any, more positive, solutions for me? :D

Yup, I understand. Most companies use this CA policy!

Hello Patrick,
we want the exact same feature to be implemented in Outlook. Therefore we created a feedback in Microsoft Feedback portal. Would be great if you and others could support it.
Hi Patrick, I have already prepared and just published an extensive article in parallel, based on a BYOD setup. Besides BYOD/MAM, this can of course also be used for Intune managed devices.

I also took the initiative to link your article and the one from Daniel Huttenlocher. Feel free to link as well if you like.

Hey folks, there is an app called Secure Contacts, which handles Caller Identification on iOS in an much better way then Outlook. The Secure Contacts app is also listed within the Intune Endpoint Manager as it supports intune app protection policies and conditional access as well.
