Currently, there is no direct option in New Outlook to set a default duration for new appointments to 1 hour. The default duration is typically set to 30 minutes, and while you can shorten meeting durations globally, you cannot enforce a default meeting time for all users in your M365 tenant. Meeting owners can manually adjust the duration when creating appointments, but a system-wide default setting for 1 hour is not available.
