Microsoft did not enable this feature yet, however, you can follow these simple steps:
1- Go to outlook.

2- Click on Address book in the Home bar.
3- Click the first contact.
4- Click on the Shift + down arrow to select all contacts.
5- Click on File.

6- Select Add to contacts.
7- Confirm the steps above by clicking on outlook contacts to make sure if all contacts were synced. 
8- Open Teams and see the Calls/ Contacts list (it might take some time to sync).
DONE, hope this solves your issue.
