How to sync all corporate users contacts to Contacts app on managed Android mobile device

@Artem Shaturskyi , Thanks for posting in Q&A. Based as I know, to let contacts created in Outlook app to sync with native contacts app. We can create an app protection policy and an app configuration policy.

For app protection policy, we can set "Sync policy managed app data with native apps or add-ins" as allow.

For app configuration policy, we can set "Save Contacts" to Yes.

You can also set the synchronization of contact fields to the native app by the following setting.

For more detailed steps, you can refer to the following link.

@Artem Shaturskyi, Thankis for the reply. After discussing with outlook support, I find the Contacts in outlook is personal Outlook contacts list which you can add the people you want. And there's no built in option to add all GAL to contacts.

But you can add contacts you want from the Global Address List (GAL) to your Outlook contacts, follow these steps:

1. Open Outlook and go to the Home tab.
2. Click on the Address Book icon in the ribbon.
3. In the Address Book window, select Global Address List from the drop-down menu.
4. Find the contact you want to add by scrolling or using the search bar.
5. Double-click on the contact's name to open their details.
6. Click on the Add to Contacts button.

This will add the selected contact to your personal Outlook contacts list

Hope he above information can help.
