If you want to create a shared contact list that everyone in your organization can access, add the contacts in the Office 365 admin center. The contacts you create here can be seen in the global address list.
How do I add contacts in the admin center?
- On the Contacts page in the Office 365 Admin Center, choose Add a contact.
- On the New Contact page fill in details and choose Add to create a contact.
How are these contacts different from My Contacts?
My Contacts are contacts that you create for yourself and your users create for themselves but others can't see. The contacts you create in the admin center are contacts for the organization, and everyone can see them in addition to their own.
How does everyone get to the contacts I created in the admin center?
Users can go to People in Office 365, expand the Directory and click All Contacts to view the contacts and their information.
Can anyone create and edit these organizational contacts?
No, only Global and Exchange administrators can create, edit, or delete these contacts. Everyone else can only view the contacts.
