Using New Outlook on Windows for personal email, calendar, and contact management
Hi Andy, thanks for your question!
Right now, the (new) Outlook doesn't let you change the default reminder options like adding “2 weeks” or “1 month” before the event. But you can still set those manually, just click the reminder dropdown and choose “Custom”, then enter your preferred time like 2 weeks or 1 month before.
Hope it helps!
Warm Regards,
Arlene D.
