Hi @anon81325277, welcome to the Asana Community Forum! As it stands, it’s currently not possible to sync an Outlook Calendar into Asana. However, you can sync your Asana tasks to your Outlook Calendar: Sync Asana + Google Calendar, Outlook, Apple | Product guide • Asana Product Guide
I recommend you voting for this request here: Real time, two ways Calendar integration
I hope this helps! Let me know if you have any other questions.
