Cannot see global address list on Outlook apps

hi folks,

Good day. A quick check what when wrong here. My handphone is Vivo Y15. Android version 9.
I set up my exchange email on Outlook Apps. Connection setting was fine and able to send/receive email.

However, when replying or sending email, it not able to search or display any of global address list from server.

And i did configure same email using builtin email in hp, it works. i just type few words and it display some email accordingly.

Please advise. Thanks.

 

did that as well. i already enable contact sync in the setting. but it didnt work.
